Title: Remington 300 Ultra Mag
Post by: HoofsandWings on January 26, 2011, 04:48:32 PM
Which rifle manufactures and models work best with this cartridge?
I know there are not a lot of choices yet.
165 or 180 grain?
Any powder recommendations?
Thanks

180 grain minimum

Retumbo

Remington 700 makes a good one.

One of the Rem 700's, a BDL if your going to pack it much or a Sendero if weight isn't a problem.
That big cartridge shines with 200's.

I shoot the sendero and it is amazing with 208's, but I also load 180 accubonds for my buddies RUM and it also drives tacks. The 180 load is hot moving just over 3600 :yike: So far my gun is accurate out to 1250 yards with me shooting it

Great Caliber.... I have a Remington Sendero that shoots excellent. As someone mentioned it is heavier to carry.

Most bullets today will get the job done.

I like the Barnes bullets, you can shoot a 165 Barnes Tipped Triple Shock faster and flatter with less recoil and get more penetration than most all other bullets of heavier weight. Out of dozens of animals shot with Barnes, we are yet to recover a bullet. They go through shoulder bone and everything. If needed it's much easier to track an animal with an exit hole.

Like any bullet, you need to shoot it out of your gun, not all bullets work in all guns. I have a 300 WTBY that shoots Rem Corelocks better than anything, it will not group Barnes or any other boattail worth a darn. :twocents:

Before I buy, I am going to take a look at the Browning. I am a fan of glass bedded barrels.
I am going to have sticker shock over the dies for reloading. Also, the powder is different along with the primers.

I have a lot of load development with the 300 rum under my belt and have built or bought 4 different rifles in the cal...if you are driving a 180 to much over 3400 legitimate fps through a chronograph.....you are asking for trouble.the diff in pressure from 3300 to 3600 is enough to make you blind if you live through a case failure. There is no reason to push 80k cup.....not worth the risk.
Title: Re: Remington 300 Ultra Mag
Post by: MtnMuley on January 31, 2011, 09:38:39 AM
What's your opinion on the 175 gr. berger at just over 3450fps?   No signs of pressures and it's not a compressed load.

I am trying to figure out how Jeremiah P can get that kind of speed, I don't see the data anywhere on how to accomplish that. Rather than suggest he is wrong, I was hoping he would share his recipe. We also have a couple 30/378's and we can't get that much speed out of them with a 180 gr either.   :twocents:
Title: Re: Remington 300 Ultra Mag
Post by: high country on January 31, 2011, 09:50:33 AM
I can't give any advice on the berger as I have done my testing with scirocco, tsx, xlc, and asst sierras.  I have made 3400 using 8700 with 180's at about 110 grs, which is closer to 65 k. The problem with pressure signs in high cup cases is they are built tougher, but once you start to flow brass.....you are on the brink of disaster. When you flow a low cup case, there is a lot less chance of it going tragically wrong...but still dangerous.
Title: Re: Remington 300 Ultra Mag
Post by: bearpaw on January 31, 2011, 09:56:46 AM
We like the performance of barnes and especially the tipped tsx, I do think they will shoot a little faster and do create less pressure than other bullets, but we still can't the speed he is talking?  I don't want to discount the possibility, rather I would love to hear how he is getting 3600 from any 180.  :twocents:

Post by: MDGrand on January 31, 2011, 01:38:42 PM
I chose the Model 700 300 RUM, XCR II.

So far, I really like the rifle. It is a heavy kicker and I have to learn how to shoot it a bit more to get the accuracy I want out of it. But, I do get sub MOA groups with the following loads:

180 grain Barnes TSX Federal Factory

and

210 Berger VLD's, RL 25, 87.9 grains, CCI LRM Primer, OAL 3.54 = 2950 fps, 0.63 BC

Going to try:

200 Barnes TTSX, RL 25, 88 grains, CCI LRM Primer, OAL = 3.6 = 3000+ fps, 0.53 BC

Two thoughts with this rifle...

If getting a Rem 700 synthetic stock that is NOT a sendero line, get an aftermarket stock, I got an HS Precision. The factory stocks suck unless you go with the Sendero line, those come with B&C stocks.

I'm shooting a model 700:

federal #215 primers

3309fps @ the muzzle

Post by: haugenna on February 06, 2011, 10:18:10 PM
3600 FPS with a 180 is false info from your buddy.  If he did, the pressure is dangerous and a slight variation in the ambient air temperature could cause a world of hurt.

I will never own another 30-378 after reloading for a RUM.  I used 110 grains of retumbo and got a 180 moving 3350 fps.  I loaded 100.2 grains of Retumbo in a 300 RUM and got the same 180 moving 3480.  More efficient with less powder.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 07, 2011, 09:04:38 AM
That is a TON of charge for a 180 grain bullet. Is that even recommended max spec with Retumbo? That sounds like a compressed load to me. I have seen Retumbo used into the 90s on some bullets but 110 grains! Wow.

I think he was loading 110 gns in a 30-378 and 100 gns in the RUM.

I have an Remington XCR also.  I have been very happy with it.  I have had my best success so far with 168 grain Berger VLD and 96 grains H1000. 

I haven't chronographed it yet, but it gets me sub moa.  My am planning on trying the 185 grain Berger VLD's next.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 07, 2011, 01:32:02 PM
I am glad that you found good results with the 168 Bergers.. I have a box of them and I thought about trying them with the RUM.

For now though, I use the Berger 210 VLD with my RUM in the following receipe:

OAL = 3.54, RL 25 87.9 grains, Nosler Brass, CCI LRM Primer. 2950 FPS, 0.63 BC. I have yet to see what it will do on an animal, but I have high hopes!

My over-all length is closer to 3.65.  I wish they would make the magazine dimensions bigger on the Remingtons, because I could go longer yet if I had that option.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 07, 2011, 02:10:56 PM
Well, my OAL when measuring my bore is longer than 3.54.. what I am saying is the ammo I made with the 210 Berger has a OAL of 3.54. that is what shoots the best.

From what I hear, a short free bore is MUCH better than a long one..

Don't want to jack this but my bro bought some 110 grain V-Max for his 300 RUM, any thoughts from you guys, or anyone ever tried them??
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 07, 2011, 02:22:09 PM
110? Can you even shoot a 30 cal 110? I wouldnt do that out of a RUM if you could.. NO WAY. 130 grains move at close to 3700 FPS.. wouldnt want to see a 110. it probably would break up in the barrel or in flight.
Title: Re: Remington 300 Ultra Mag
Post by: LittleJohn on February 07, 2011, 02:24:59 PM
V-Max makes them in 30 cal. I know a few guys running them in the 30.06's. I am sure them are screaming. My bro wanted me to ask if anyone knows anything on here about running them in the RUM :dunno:

Post by: whacker1 on February 07, 2011, 02:36:45 PM
I understood what you were saying.  I don't remember the actual dimensions, but I will give it a shot for purposes of illustrating my dilemma:

OAL for the chamber is like 3.77 in my rifle.
OAL for the magazine is like 3.7
so to get the loads to move up and down in the magazine I have them at 3.65.  The closer I got to the lands the better mine shot in regards to accuracy, but I had to back the length down to be able to use the magazine

Most Remingtons I understand are plagued with the same problem of short magazine length.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 07, 2011, 02:44:19 PM
I totally see what your saying.. my OAL length I think is almost identical to yours.. 3.7.. magizine is a bit shorter. BUT.. I think this is pretty common across ALL factory rifles.. they have to live up to SAMMI specs, as making a rifle that shoots bullets well seated in the lands can cause excessive presure. Plus they need to feed properly

MAYBE.. there is an aftermarket magazine that will let you go to the full lengh?

I am thinking about gettng the HS Precision Detachable magazine.. perhaps that will come with a longer OAL?

I would ask for the specs on the magazine.  I know others that tried to change it and have had no luck in doing so.  They were going to resort to taking a dremel to a stock to make it bigger, but I haven't been willing to go that direction..

You 300 RUM owners who have a REM Sendero do you know what twist the barrel is?
Also I was wondering if someone with a Sendero has a fast accurate load for any of the following bullets they would share?

Barnes 110 gr  Tipped TSX FB
Barnes 130 gr  Tipped TSX BT
Barnes 150 gr  Tipped TSX BT
Barnes 168 gr  Tipped TSX BT
Barnes 180 gr  Tipped TSX BT

Any accurate loads for the standard TSX would be worth trying too, THANKS, Dale

3 round.  

you basically are taking out the trigger guard and hinged floor plate to put in a solid piece that allows for the detachable magazine.  I don't believe it gives you any longer options for the COAL.  It would be worth a call or e-mail to find out.  It is a $300 change by the time you ship and pay tax.

102 grains of retumbo, be careful it is a very compressed load, and my buddy says its not fun to shoot :chuckle:


I shoot the sendero and it is amazing with 208's, but I also load 180 accubonds for my buddies RUM and it also drives tacks. The 180 load is hot moving just over 3600 :yike: So far my gun is accurate out to 1250 yards with me shooting it

Hey Dale.. Here are the results from my 200 TTSX Load:
Again, the recipe: Federal Nickel plated Brass (I only have this because I went through a box) 200 Grain TTSX, OAL = 3.64 (this is seated -0.02 off the lands so this may be different for your load), RL 25, 88 grains (this is max), CCI LRM, Rem 700 XCR II, 26" barrel = 3150 FPS. BC on this bullet is 0.546 too.. so should be a super nice accurate load out to 500 yards.

If you have a sendero with a heavier barrel, you will probably get even better results. Good luck.
Title: Re: Remington 300 Ultra Mag
Post by: bearpaw on February 09, 2011, 05:40:08 PM
MDGrand, That's really good shooting, I will have to try working up to that load when the weather warms up. My gun does have the heavy barrel, but I doubt i can shoot much less than 1" groups because I am not the best shot. It's a gun I bought from a guy who needed money, it's in great shape and it shoots really good, I have seen several targets. I have not shot this gun yet myself, but I want to work up some Barnes TTSX loads for it.

Have you shot any of the lighter TTSX bullets?
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 09, 2011, 05:52:53 PM
Thanks, Dale.

In all fairness, this was done off a nice bench rest with front and rear supports, there is little I had to do. When working up the load I try to make sure I find out what the RIFLE can do with a load first, then I find out what I can do with it. There is no need to shoot MOA groups off hand or free hand in order to get a nice clean kill shot on an animal.. as they say, if you can hit a pie plate at 100 yards that is usually good enough. So I practice off hand and more field type shooting positions at the range after I find my good loads.

The Sendero though is a flat out nice rifle.. top of the line from Remington from what I understand. That should shoot 1 MOA all day!

I have not shot any lighter Barnes TTSX bullets out of my 300 RUM, albeit the TSX 180 federal factory ammunition I got the brass from. For a 300 RUM, I try to shoot the biggest bullet I can find with the best BC. If can shoot damn near or over 3000 fps with a 200 grain bullet and the bullet has a BC of over 5.. that means the bullet is gonna have a nice flat trajectory and be real wind resistent.

I have shot 3 different 300RUM's and they were all tack drivers. didn't seem to matter what bullet we tried. I would like to caution anyone trying to get excessive speed from a gun. I know from experience it is not worth ruining a gun for.

I agree with using the heavier bullets. In a conventional bullet such as the Nosler Accubond I'd go with the 200 grain and the high BC that goes with it. With a Barnes I'd go a little lighter- down to 180's but not any lighter. If you want to shoot lighter than 180's you might as well be using a standard 300 Win Mag or a 30-06. Just my opinion.

Well, If they work well for ya, more power to you! I know the Berger VLD bullet was originally designed for only target shooting as well and they found out it worked well for Hunting. So what is your experience with them as far as performance? Do they act like a ballastic tip?

Title: Re: Remington 300 Ultra Mag
Post by: Antlershed on February 10, 2011, 08:45:42 AM
I have never shot ballistic tips so I'm not really sure how they compare. The first deer I shot with the Amax's was at 585 yards, and it just clipped the offside shoulder on the way out, and there was very minimal meat damage. My deer this year was shot at about 100 yards, and I shot it in the neck and dropped him in his tracks. Wasn't a huge exit wound either. My elk this year was a neck shot at 250 yards and she dropped in her tracks and didn't have a huge exit wound either.

So are the A Max's a bonded core bullet meant for weight retention, or are they meant to blow up like a ballistic tip. I would imagine if they say they are NOT recommended on game it is due to their inability to stay together or give a delayed expansion.

If you guys are getting such great hunting results, especially in an ultra mag then I wonder what Hornady's position is on this bullet.

I would love to try it. Currently, given the low BC of Hornady bullets I am not a fan. Too many other bullets like the Barnes, Berger and Accubond that I think I superior.

It's not really correct to say that ballistic tips are "meant to blow up." The ones designed as varmint bullets, probably, but the ballistic tips designed for hunting big game are definitely not designed to blow up. I'm not saying they WON'T. It really just depends on the specific circumstances- bullet caliber/weight, velocity at impact, bones hit or not, etc.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 10, 2011, 09:36:39 AM
Well, I am going to have to disagree slightly with you. We are starting to get in the "better bullet arguement" So I will tread lightly as its all seamantics.. everyone has a favorite and a way of explaining  :)

I agree that they are not varmint type bullets, but they are meant to shed about half their weight sending shards all over and inside the animal, according to nosler ballistic tip web site, they are meant to expand "on impact." I have seen what they do on deer and they will kill it, sure. I would not want to use them on larger Muleys though or elk, bear, etc. I think they are best for White tail, black tail and even some varmints. But this is just my two cents.. some guys MUST have an entrance and exit hole.. others think that by the bullet blowing up that ALL its energy is now dumped into the animal and that is better.

Whatever the case, the common factor in all, is shot placement.. So whatever one you can shoot straiter, use it.

Yes, but the hunting VLD is still a different bullet than the match/target VLD.  That's like comparing the A-Max to the V-Max.  Just because they look alike, they're totally different.

I know they are different.. all I am saying is the Hunting VLD used to be JUST a target bullet, they FOUND OUT it was effective on game and slapped a hunting name on it. I was not comparing the two.. just saying that perhaps the A Max will soon be slapped with the Hunting designation too if guys like the ones on this board keep taking animals reliably with them.

Post by: MtnMuley on February 10, 2011, 10:29:30 AM
The target/match VLD was originated as a target bullet, not the hunting VLD.  The hunting VLD was disigned specifically for hunting.  What I am saying is that they are NOT the same.  They are totally DIFFERENT bullets, not just a swap of names.
Title: Re: Remington 300 Ultra Mag
Post by: MDGrand on February 10, 2011, 10:41:50 AM
Holy sh*t.. ok seems like we have a chicken and the egg argument here. .. from my undestanding the Hunting VLD was discovered as a good Hunting Bullet but was originally designed as JUST a target bullet first. After discovering that the VLD bullet was good on hunting, they slapped a Hunting name on the VLD logo and then set out to make another bullet meant just for target shooting.

Whatever the case, I will let you be the expert, I just shoot em.

JoshT told me of a kill that his buddy made on a bear at 575 yards with the Amax, if I remember correctly they found the bullet on the opposite shoulder and it retained 80% of original weight. So I don't think it's made to fragment out like a ballistic tip :twocents: I wish JoshT was here to weigh in on the topic

I know a few folks that have killed a bunch of deer, elk, and blackbear with A-max's and swear by them. Put the bullet in the vitals and it will kill, but don't try to reach the vitals through the rear hams. As well as A-max's shoot in some of my rifles, I save them for long range playing and use other bullets for killing.

OK.. Looks like I have come across one of those guys that takes this site WAY to seriously.. RELAX.. I am not in your living room or at your front door. Its clear you have a love affair with Berger and want to keep the truth to what you believe it is. I really dont take all this, especially what someone else says over the internet,seriously. But since it seems to be THAT important to you.. I will share one last time and then I will drop it. Reply all you want (and I too apologize to anyone else that is reading this...)

What does that have to do with anything? Well, you pretty much outwardly insulted my sponsership of Rivers West, so I was wondering what great product or service you are endorsing? You ARE a "sight sponser" are you not? Are you "too proud" to share?

As far as where my knowledge comes from regarding the Berger bullets:

1. One of the guys on the RW pro team is also sponsered by Berger.. at the SHOT show a few weeks ago, we hung out with the Berger guys.. They told me the design of the VLD was originally conceived as a "competition bullet" as Walt Berger was a competition shooter. Others at Berger and in the Industry (Best of the West TV show for example) found out that it was a very effective game bullet as well. SO, they set forth to create two lines, the "Hunting VLD" and the "Target VLD".. here is the video on Berger's site that says in the very beginning that "the VLD bullet was intoduced as a competition bullet..." The Berger VLD - Best Long Range Hunting Bullet (http://www.youtube.com/watch?v=voyw1H-0CBI#)

So how do you interpret that? I know that there are two different lines of bullets, I KNOW that there is a Target and Hunting VLD, so I don't need a lesson.. it seems to me that the inception of all of their bullets ORIGINALLY came from a need to design competition bullets first and that ran into their now Hunting VLD line... hence my original comment in this thread about perhaps the A Max being converted into a Hunting bullet as well, based on the experience of other hunters and two it seems apparent that this was the path that lead to the Berger Hunting VLD.

Regardless of all this, if I am wrong... and they misinformed me or I misunderstood.. who cares. Its lame, the argument is lame. I wasnt trying to purposely give "false" information or "lies and bullsh*t" as you said in a previous post. I didn't take any shots at your product or business (even though you wont say what that is), and I never called you liar or said you were full of "bullsh*t" .. you did..

Again.. sorry to anyone reading this thread as this is SOOO stupid :P

I've killed more than 50 deer  and antelope with Rem. Core locks and a few with Nosler Partitions.  Neither killed any better than the other.  And for what it's worth, niether of these killed any quicker than a load of OO/O buckshot at 30 yards or a round ball from my .54.  My firm belief is that all the designer bulets out there are disned for one thing, to make more sales by companies that don't produce the same bullets as other companies.   Will those kill any quicker?  Nope.  But they will kill just the same.

As to penetration, I know deer don't offer the same resistance as an elk or bear, for example.  However, I did, on accident, take two whitetails with one shot.  One standing behind the other.  The exit hole on the second deer was no larger than the entrance hole on the first.  One deer dropped like a rock.  The other left a blood trail Stevie Wonder could have followed.

Hoofsandwings, Scirroccos are the bullet he has chosen to shoot. I have a wood stock version (CDL) of the rifle and the recoil is manageable. I am a large guy though (over 300)...not sure how it would feel if you were 150lbs or so....

I reseached the 300 as much as I could before I purchased one. Finally bought it and put a 5.5 X16.5 nikon on top of it and never looked back. First it destoyed a simmons scope :chuckle: :chuckle:

I wanted one gun to hunt everyhting with. This gun has outdone any expectation I could of ever imagined. I'm not a gun PRO by any means and shoot less than alot of people. But when I pull the trigger I always feel very confident I can hit just about anything.
That is at a resonable range, People say this cartridge will go way out there but if you are shooting at anythng past 500 yards I think you have missed a step in "HUNTING" somewhere.............
