Title: .300 BLK load thread
Post by: CP on May 01, 2017, 09:22:56 AM
I’m finding conflicting data on loading for 125g bullets in the BLK.  Hodgdon data gives a max load @ 21.0g of Lil’Gun.  Nolser data gives a max load of 18.0g Lil’Gun for the same bullet.  Hornady lists 19.5g max for their 125g SST.

I don’t know who to believe.

I’ve loaded the 125g Hornady SST to 18.5g Lil’Gun without any pressure signs.  It’s plenty accurate for a hunting load and shoots very flat out to 225y.  I’m not sure if I should try pushing it any further or not.

Anyone else loading the .300 BLK?

I shoot the 110gr Barnes Tac-X
20.2gr H110
CCI 400
2.250

Federal mil-spec brass.

I found once fired brass trimmed, and sized to .300 Black Out. Polished and gauged. Just load and shoot for $110.00 per 1000 Shipped.

I've run H110, with 125gr Noslers, and 130 Speer flatpoints for a while now.   130's with 17.0-17.5gr H110, work really well on deer, and have a text book mushroom at blackout speeds.

I just built a AR to try the chambering. I don't care for the cartridge at all, with the acception of subsonic loads and a suppressors.

For taking big game I would rather shoot a AR chambered in 6x45, 25x45, .243 LBC, 6.5 Grendel etc.

I've taken 2 deer with the 130gr TTSX out of a 10" contender in 30 Herrett which gives velocities about 150fps slower than the 300 blk from a 16" rifle. They were both small deer at under 100 yards but both were DRT with good shots. The 300 BLK isn't a power house but it's not terrible if you're smart about your shots.

When I had a 10" 300 whisper I ran the 125 NBT and H110 good results at around 1700 fps.

Have you tried Lil'Gun with these bullets?  Book data shows higher velocities at lower pressures than H110.  I've tried both and don't see a difference but I don't have a chronograph.   I need to breakdown and buy one.

I like the 130g Speer but I have feed issues with it.

I haven't tried Lil Gun, in my blackout, I really was chasing accuracy more than velocity, and H110 gave me everything I was looking for.  My blackout is a Rem 700, and it was hit and miss with the 130's until I got the seating depth just right, now it feeds smooth.  The same 130 flat points feed great in Ruger American Ranch rifles as well.  I was getting around 2000 fps with the 130's.  I don't have my notes on hand to tell you exactly.  Accuracy was sub moa in my gun <3/4" 100 yards. 

Completely off topic, but I'm really wanting to shoot the new ruger American ranch 450 bushmaster.   It looks like it would be a stellar brush gun.

I tried lil gun and h110. I run h110 with all my blackout loads super and sub sonics. I run the 125g ballistic tip for my super. Have shot a few coyotes with them and I would not have a problem shooting a deer with one at a reasonable range.

Do you mean a Ruger Ranch rifle? As in, a Mini-14? If so, you're doing pretty well with it, they are not a target rifle. I would think that's about as good as you could expect with one of those; it's not the caliber, it's the rifle.

Post by: CP on July 07, 2017, 09:26:24 AM
Subsonic loading:

Sierra 220g RN with 1680 powder:
10.8g – velocities: 1036, 1026, 975, 965 (fps)  - 3” spread at 75 yards
12.0g velocities:  1108, 1070, 1043, 1047, 1092 (fps) – less than 1” at 75 yards

These all stayed subsonic (Mach 1.0 = 1128 fps @70 degrees F) but I’d like to figure out how to tighten up the velocity spread.
Title: Re: .300 BLK load thread
Post by: Yondering on July 07, 2017, 11:39:25 AM
Those 12.0gr velocities are too high for subsonic use - they'll crack a little bit especially in cold weather.

Remember, there's not a hard cutoff between supersonic and subsonic. Your faster loads are in the transsonic range and will make more noise than you'd want.

Post by: Yondering on January 11, 2018, 09:39:09 AM
I'm curious why you would choose a 150gr load for hunting with this round, instead of a 125gr that works better within the velocity range of the Blackout?

I'm not 100% sure about that Hornady 150gr SP you're using, but I think it's intended for a higher velocity rifle (308, 30-06, etc), so you're probably pretty close to the minimum expansion threshold at the muzzle. With a lot of high velocity rifle bullets, you can't expect much/any expansion below ~1800 fps, which gives you a pretty narrow effective range with that bullet for good terminal performance.

If you were to use a 30/30 bullet of course, intended for lower velocity, that would be a different story, or one of the good lighter bullets started at higher velocity.

Here's a good read on the subject.

I intend to do some expansion testing to determine the max range but I don't intend to use it for long distance hunting.

Most 300blk is getting 2300 fps at muzzle , so unless your gonna stay at 50 yards or less ,your not gonna get the expansion your looking for ,think varment bullets will expand, like these

At the fps blackout put out they won't explode like it would out of a 3000 fps rifle ,i have played with the blackout for two years and learn the hard way ,barnes makes the best expanding bullets for blackout , but there's a cost factor,and lots of options. :tup:

Not with a 150gr.

CP, you really gotta think about down range velocity, not just muzzle velocity. You're not stacking the odds in your favor with those bullet choices. Why not use something more appropriate to the cartridge?

I was just saying in general with any bullet,that 2300 fps is about tops at the muzzle,and do agree lots of bullet choices,If your looking for extra wt bullets,I would look for 125 grain varment bullets good expansion ,varment bullets are not gonna fragment much with the low velocity 300 blk.

No, I'm not going to shoot a deer with a varmint bullet.  I'd rather have a no expansion pass through than blow fragments 5" under the skin.

I've done my research and have spoken with folks that take several deer and hogs a year with the 300 BLK.  My 1st choice is still a 150g bullet - 2nd choice would be the 125g SST that I posted about earlier.  Nothing lighter than that.

I have no debate that sst will work for deer 100 yards and less,anything over 100 yards I don't think you will much expansion.

Here's a artical I read awhile ago on the set for 300blk.

https://www.google.com/amp/s/www.outdoorhub.com/amp/index.php/breaking-5-different-300-blackout-loads-terminal-ballistics

This is a 300blk forum maybe your a member already but if not lots of info,and people they say it does work.

http://www.300blktalk.com/forum/index.php

This is from hornadys website which says expansion is best a higher velocity.

The Hornady® SST® is designed to deliver tremendous shock on impact while expanding quickly and reliably, particularly at higher velocities.

I'm not a Barnes bullet fan but Barnes did design their 110gr TAC-TX for .300 Blackout velocities. They shot well in mine, shot between 1/2 and 3/4 MOA with a 16",  1-8 twist Anderson Arms barrel which my cost is about $70.00 bucks, maybe less can't recall exactly.

You should do some better research then. The two best 300 Blk hunting bullets available are the 110gr Barnes "black tip" and the 125gr Nosler Ballistic Tip. Both penetrate deeply and expand well without fragmenting within the 300 Blk's velocity envelope.

I'm still curious why your first choice is a 150gr bullet for this cartridge. What is that choice based on?

Don't be so narrow minded as to just think "varmint bullet = bad". So called "varmint bullets" for high velocity rifles are built with the lighter construction needed for normal expansion at the lower velocity the 300 produces. Not all, but most of the 30 cal "varmint bullets" act like traditional hunting bullets at 300 Blk speeds and penetrate deeply. And if you rule out something like the 110gr black tip just because of the weight, you're misunderstanding a lot.

Also do not confuse the black tip Barnes bullet with the blue tipped option of the same weight; that one is designed for higher velocity and is a completely different bullet, and not really appropriate for the 300.

Look at some of Mr. Mileks load data of low velocity varmint bullets in the Herret and the TCU chamberings. Low velocities, the "varmint bullets" shine on big game!

Thanks Hunter399 - I wasn't aware of that forum.  Looks like a lot of info there.

I have read that Outdoorhub article.  His velocities are on the low side e.g. 1915 fps for the 125 SST.  I’m getting:
125 SST – 2350 fps
110 Barnes – 2410 fps
150 SP – 2010 fps

This guy has some great data on expansion if you haven't seen it:
https://thebulletterminal.weebly.com/

No doubt the Barnes bullet expands great, but if the Chuck Hawks KPS method has any credence they made in too light.  I've never been a fan of light bullets.

This is what I'm getting:

                  KPS @ 200y
150 SP          15.0
125 SST        14.9
110 Barnes    10.7


The 150g SST should come in even higher given it has a better BC.

but if the Chuck Hawks KPS method has any credence

It doesn't. It's an arbitrary number made up by someone who doesn't understand what they're calculating. For example, the calculation includes multiplying sectional density by cross sectional area. Do you know what sectional density is and how that's calculated? It already includes cross sectional area. Whoever made up that formula just put some arbitrary factors together to support what they'd seen on game, ignoring bullet expansion probably because they assume it will happen.

You're completely ignoring whether or not the bullet will expand at all, and going by someone's arbitrary meaningless calculation instead. Awesome.

So you're "not impressed" by the 110gr black tip bullet - have you actually shot anything with them? Even done any penetration testing or anything like that?

The bullet you're choosing is likely to pencil through without expanding if the range is much farther than a pistol shot. Ignoring that because you're certain that bullet weight is more important is very likely to result in a wounded animal.

You're probably right about Chuck.  And I'll do expansion testing as I stated earlier - I'll post the results when I get them.

If your really want weight with expansion I would look at these.I have shot water jugs with amax ,seemed ok.155 grain amax and its not a varment round.

https://www.hornady.com/bullets/a-max#!/

Then I think might even be better is lever ammo,140 grain and its says at bottom that it will expand down to 800 fps.

Haha, always a good time with that kind! Sorta hard to measure the penetration though... :)

CP - if you really are stuck on using a 150gr bullet for a cartridge designed around 110-125gr, then your best bet is a 30/30 bullet. The FTX as mentioned above or Core-Lokt RN work for that velocity range. The performance isn't better than a 125gr BT, but it's decent anyway.

The ones I'm talking about are the monoflex ,it's the 800 fps - 2000 fps with good expansion.

Well I got all winter, spring and summer to figure it out.  If it doesn't work I'll find out and post whatever failure or success I come up with.  I've got 11 other .308 bullets from 110g to 220g on the bench to work with or one of the other suggestions above. 

I enjoy the process otherwise I'd just buy a box of ammo and call it good.

Well this is not what I expected.  50 yard shot with the 150g  SP interlock.  Straight through 13" of gel, 2 sand bags, bullet lost somewhere in the sand trap but it's obvious there was zero expansion.  Minimal wound channel.  .30 cal exit wound.  Total failure.   :tdown:

That 110 will get the job done. I bet the 120gr Nosler Ballistic tip would perform well. Hard to beat the performance of that Barnes 110 though.👍👍 For volume shooting the Nosler would be a whole lots easier on the wallet.

If you keep checking the Nosler Seconds site. When the .30 120gr BT's come into stock, you can get them for 16.00 per 50.

http://www.shootersproshop.com/nosler-products/shopby/f/caliber/30/isAjax/1.html

They have the 220gr RN-Blackout Ballistic Tips in stock for Sub Sonic or Super sonic loads. $18.00 per 50.

Sorry, I don't believe everything that I read on the internet.  But for the record, you were completely right, I was completely wrong.

I know a manger of a ranch in South Texas who uses a .300 SBR to control hogs.  He shoots dozens a year and he swears by the 150g bullet.  So, yeah, I was determined to give it a test.  Now it's relegated to plinking steel plates, which it does very well, smacks them with authority.

Cp are you making your own gel or buying the kits? What’s your recipe if you don’t mind sharing if you are doing it DIY.

I make my own.  The base recipe is 1oz powdered gelatin to 1 1/3 cups water. 

https://www.amazon.com/Knox-Unflavored-Gelatin-1-lb/dp/B001UOW7D8/ref=sr_1_7_s_it?s=grocery&ie=UTF8&qid=1516674355&sr=1-7&keywords=gelatin


Just mix the powder into cold water.

That mixture goes into the frig for about an hour (don't worry about getting it clear at this step, just get the chucks mixed it.

then melt and warm that using a double boiler, get it hot to the touch, it will be pretty clear by then (clear enough anyway)

then pour it into a mold of your choice (I use Pam so doesn't stick)

back in the fridge over night

Remove it from the mold, done.


It's not to the FBI standard, but it works.

To re-mold cut it into chunks and back in the double boiler or put it in the oven at 200 degrees until melted.

Awesome thanks  :IBCOOL:

I have used lots of different stuff to catch bullets and test expansion but never the gel itself. Will be nice to test a couple subsonic bullet loadings, I am curious to see if there is much for expansion on.

Gel test #3 – 125g SST at a “simulated” 150 yards.  Simulated in that the round was loaded down to the 150 yard calculated velocity.   Target velocity was 2010fps and it came in just a bit hotter at 2022fps.  That would be about 1135 ft-lbs of energy at impact.

The bullet passed completely through 13” of gel and lodged in the 1st backing sand bag.  There was an exit wound in the bag where it looks like a large piece of jacket exited (unrecovered).   

Recovered bullet weight was 92.5g (74%).  No fragments were found in the gel, many were found in the sand bag.  Damage to the block was extensive, almost severed in half down the middle.  Significant permanent wound channel.

While I’m not thrilled with the weight retention, it appears that breakup occurred after passing through the gel.  Bottom line is this will get the job done with plenty of energy to spare for a bit more range.

Post by: Biggerhammer on January 24, 2018, 11:16:55 AM
Interesting! Maybe it mushroomed at that velocity, which caused the trauma to the gel and came apart on impact with the sandbag. Either way it would sure do some damage to a deer.
Title: Re: .300 BLK load thread
Post by: yorketransport on January 24, 2018, 11:47:26 AM
I bet it would have retained more weight if it hadn’t hit a sand bag. Sand will tear up a bullet.
Title: Re: .300 BLK load thread
Post by: Biggerhammer on January 24, 2018, 11:56:54 AM
Maybe a couple milk jugs full of water behind the gel block to catch the bullet?
Title: Re: .300 BLK load thread
Post by: Yondering on January 24, 2018, 12:03:23 PM
yep, more water jugs or wet paper to catch it.

That 125 SST is known to come apart a little easier than the 125gr NBT though, so that weight retention isn't too surprising and probably a good reflection of what it would do on impact with bone. That's why I recommended the Ballistic Tip or Barnes 110 black tip earlier.

I'll try a down loaded Barnes next with some water jugs as backup.

Gel test #4 – 110g Barnes TAC-TX

Target velocity was 2014fps to simulate 150yards but again I came in a bit hot at 2080fps, so more like 125 yards.  1057 Ft-Lbs of energy.
Recovered weight = 107.5g.  Text book expansion.

I ended up using newspaper as the 1st backstop and the bullet penetrated the 13” of gel and was recovered about ½” inch into the paper. 

The permanent wound cavity was quite a bit smaller both in diameter and length than the SST’s wound cavity.  Expansion started less than 2” into the gel and the major damage only went about 5”.  Considerably less overall damage than the SST produced. 

I haven’t formed any hard conclusions yet but it appears this is near the edge if not already beyond the effective range of this bullet.

I've tested that bullet down to 1600 fps with similar results to what you saw. It seems to give pretty consistent performance across a wide range, but like you saw it (and other mono bullets) aren't as explosive as a lead core. They do tend to penetrate pretty well despite the light weight. Barnes says it expands down to 1400 fps, and based on what I saw at 1600, I believe it.

Midway now has the 125 Nolser BT in stock.  I think I'll give them a try next.

125g Speer TNT @2194 fps.  This one penetrated 4 or 5 inches then, boom,  :yike: blew pieces of gel everywhere.  Found the lead core and a hunk of jacket just outside the gel block and 3 other pieces of jacket in gel bits that I picked up.  Total weight of the bullet bits was 113g so I found most of them.  Messy clean up. 


Very thin jacket on this bullet - for varmints only.

I think they're both pretty cool but the 527 would definitely be a lot more useful, that's for sure.
