Title: 7mm mag powder?
Post by: gonehuntin68 on June 05, 2016, 10:12:34 AM
New at reloading and have done some research on powders. There is just so many of them it's hard to choose. Wanna see what you guys think. Tc venture, 24 inch barrel, 1 and 10 twist.

My Rem 7 mag loves Hodgdon H1000.  I'm sure others will have options as well.

As you said, there are so many powders available for 7RM. Which projectiles are you looking at using? H4831(sc), H1000, Retumbo, IMR 4831, RL22, to name a few, are some of the most popular. Being that you're new to the game, it is best advised to use a good reloading manual (Lyman, Hornady, etc.) and start with the beginning loads and work up. While it is very tempting to use a load that you find posted on the interweb from Billy Bob, don't. Bad things can and do happen. Have fun with it.

I like Hodgdon powders. For the 7 mag I'd go with either H1000 or H4831.

Powder is in short supply though, so you may have to go with whatever you can get.

I use imr 4831 at 60.4gr at 3000 fps.162 sst bullets.out of a savage 111.This load has proven the most accurate at 100 to 500 yrd's. My best 5 shoot group at 100 is .950.
   This load I found has mild  recoil along the line's of an .06.
   Be advised this is a max load , u should work up to it and look for pressure sign's.
   I use the 162 gr sst because of the bc at 0.550. This bullet will put them down hard!


    my bad,not 1.950 but .950.     helps to use my glass's.....

Now, is that sushi from the old "Jims's Stab-N-Grab" or a legit gas station like AM/PM?

As far as powders go, a good reloading manual will have some recommendations that worked well while they were developing data. A magnum primer and some IMR 4831 is a pretty combo to start with. Just pick a bullet and track down good data from either the powder or bullet manufacturer. Hodgdon had a great online data base that covers Hodgdon, IMR, and Winchester powders.

Which is the exact same powder as Reloader 22, so that's nice in that if you can't find one at the store you might find the other.

No, it's not. They are similar but not identical.

This is poor advice at best. Providing information like this to an admitted new reloader is dangerous and bordering on negligent. Unless you have access to the proper equipment or adequate experience to make powder substitutions, it is a poor idea to do so. The OP has neither and I suspect that you don't have the appropriate equipment or technical background to do so either.

Yorke, I would assume the OP  would use r22 with 7rm rl22 data. I may be wrong.
I don't think bobcat was saying use the 22 in place of MRP.

I also use IMR 4831 (62 gr) with 160 gr nosler partitions...not to stir up a hornet's nest as i usually don't critique other's success but if your "best" 5 shot group is just under 2" at 100 yards you may want to re-evaluate your load.  My browning A-bolt is almost 25 years old as well as the Vari X II Leo on it and it will group better than a bunch of crack heads looking for a dropped rock.  Good luck and keep your powder dry

Take a look at this thread on 24 Hour Campfire. Even John Barsness (Mule Deer) is saying they're probably the same powder, and if not they're so close that you could use the loading data interchangeably. Of course starting 10% below max and working up like always.

http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/6532901/What_s_the_scoop_with_Norma_po

And here's a quote I saved a few years ago from someone in the know:


"For our European and African friends, who may have difficulty locating the various powders, there is an authorized substitution. Reloader-22 is exactly the thing as Norma-MRP. Reloader-19 is exactly the same thing as Norma-204. Reloader 15 is exactly the same thing as Norma-203. These powders come from exactly the same plant and are made at exactly the same time. The powder from that plant is simply shipped to a different place and is put into a different consumer pack."

http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/6532901/What_s_the_scoop_with_Norma_po

Backing up internet facts with more internet facts is like referencing Wikipedia in a doctoral thesis; it shows a complete lack of first hand knowledge or meaningful research.

Unless John Barsness is a chemical engineer for a powder manufacturer he's no more qualified as a source for information than some guy over on LRH with the screen name CrazyLary'sReloadingData. I'm not very familiar with John Barsness but my understanding is that he's a journalist, albeit a successful and prolific one. But how many people have criticized journalists for providing false information over the years? How many incredibly well qualified journalists are called liars everyday by internet experts with no actual knowledge on the subject matter? So if we can't trust those journalists, why can John Barsness be trusted on this topic?
 
I've know for years that Reloader 22 and MRP are very similar but that doesn't make them "nearly the same". Hodgdon's H870 is "nearly the same" as WC 872 but that doesn't make them interchangeable. Hodgdon H110 and Win 296 are "practically the same" but that doesn't make them interchangeable. The burn rates are variable between lots of identical powders (look up the great debate over H1000 and the new-VS-old burn rates) so imagine the differences possible between different lots of different powders.

I stand by may statement that you're providing potentially dangerous information without a reputable and verifiable source for the information. While many shooters are smart enough to extract actual facts from the volumes of "internet wisdom" out there, I sure wouldn't want to assume that everyone is capable of doing so. Just because the "google box" says it, doesn't make it true. :twocents:

Google "Norma MRP and reloader 22." There's plenty of discussion to be found on all sorts of Internet forums about the similarity of the two. I don't find these discussions "dangerous" in the least. Maybe you do, but that doesn't mean I'm not going to post about it, as I find it an interesting subject to discuss. As I said, you always start below max and work your way up.

Post by: RadSav on June 05, 2016, 05:06:43 PM
Not sure about the RL22 and the MRP being the same.  I had lot to lot variance that was quite severe with 22.  My MRP load of 68 grains does fall within that variation.  So I suppose it could be.  But so far with three different lots the MRP has been stable.  Not a huge base of measure, but so far so good.

Now N203B and R-15 have both been stable and run exactly the same powder charge for velocity in my 308.  So I can believe one is just a rebrand of the same thing between those two.

We use a lot of N204 around here.  I have not gotten a 257 Roberts load of 204 to be anywhere close to the R19.  I have only used a single lot of 19 so that base measure is limited.  But I would be surprised if they were suppose to be identical.

This gives me an idea for a new thread!

Maybe you do, but that doesn't mean I'm not going to post about it, as I find it an interesting subject to discuss. As I said, you always start below max and work your way up.

Using a google search to validate a google search? That reminds me of an 8 year old asking a 9 year old to verify a mathematical proof for him. It's entirely possible that it will all work out to be correct. It's also possible that they both come to the conclusion that the correct answer is not 14, it's actually a kitten. (For the record that joke is hilarious if you're a big enough nerd)

There are a lot of fascinating subjects that are fun to debate and discuss. There are also better places to give speculative advice than in a forum topic where a new reloader is asking for advice from experienced individuals. As I sit here putting the final touches on a new chamber reamer design I would love to discuss the impact of small changes to case shoulder and leade angles as it pertains to peak pressures. I'd also love to discuss why my wildcats can be safely loaded with higher charge weights than similar designs. The problem is that not everyone can differentiate between speculative or theoretical advantages (or in the case of Reloader 22 and MRP similarities) and proven fact. Advanced reloading is best left to the realm of advanced reloaders. After all, none of us would want to be responsible for recommending that somebody use pistol powder in a 30-06 case for reduced loads An inexperienced handloader may find that information while doing a google search and hurt them self or somebody around them.

What more can I say? If you don't like what you're reading, stop reading it. I can't guarantee with 100% certainty that they are the same powder. But people who are much more knowledgeable reloaders than I am, say they are. You don't want to believe it, then don't. I'm not worried either way.

Nothing hopefully. As a forum moderator I would like to believe that the safety and integrity of the forum and it's members is a priority for you. This is not the first time I've seen bad or downright dangerous reloading advice posted by you and others on here.

Jay.sharkbait's comment was tongue in cheek, but still some of the best advice I've seen on here. Far too often reloading experience and reloading skill are confused, here and in the field. It seems to me that the person with the most experience typically isn't the person with the most skill.

The Hunting-Washington forum is no less, and no more, reliable as a source of data from any other internet source. Every reloader should have at least a couple reloading books, and even then you can't trust the data 100%.  But I think it's unfair to make it sound as if this site in particular has data posted that is dangerous or unreliable.

Wow if I can't trust my local forum for advice the why are we here. I have gotten nothing but great advice from every member on here. From hunting styles hunting spots  all very helpfull. And tasted better than gas station sushi or any sushi for that matter. I am a new reloaders and would not hesitate to take advice from a guy like bobcat. I am currently loading .308 savage model 10 and savage lrh 6.5x284  . Been studying up on the Interweb for a year before loading a round.  In that I have seen many references to the norma mrp 22 being made in the same factory/being the same powder. A smart man would double check any loading advice and start low and work up. A smart man would probably avoid sushi period.

I agree. But I see more bad info shared here than on the limited number of other forums I'm on. I also see far more questions asked by new reloaders here than on other forums. That combination is concerning. Far too often the bad information drowns out the good and goes unchecked. The rebuttal to anyone questioning the bad info is typically a cut and paste response from an Internet search. This shouldn't be a surprise, but backing up bad info with bad info doesn't actually help.

You're not the first one to accuse me not being any fun. Typically I hear that from my employees and my kids though. I get on my employees, kids and friends about unsafe behavior daily. It's my job, my responsibility and my pleasure to do so. As an advocate for the shooting sports it's your responsibility to do the same.

I'm not talking down to you, on the internet everyone is on level ground. That's the problem. Congratulations on your 32 years of reloading. I'm only at about 18 years. I double checked my records and in that time I've reloaded 67 different calibers (27 of those are wildcats and 6 of those are ones that either I designed or worked with the designer) in 142 different rifles. I think my parting comment will be a quote from myself.

Far too often reloading experience and reloading skill are confused, here and in the field. It seems to me that the person with the most experience typically isn't the person with the most skill.

Im with bobcat, if your dumb enough to take anything off the net and load it up for yourself you probably shouldn't be reloading at all. The work your way up is an obvious statement, again if you don't understand that THEN YOU HAVE NO BISNESS RELOADING!

All good and well, but new people get into reloading all the time.   We should be helping them as much as possible, in which case working your way up etc. is good advice every time.   I know I started reloading 30-06 cartridges when I was 8.  The concern isn't so much for everyone, but for new reloaders and youths.  Generally, the younger generation gets most of their information on the net.  So it is wise to include disclaimers.


Edit to add: I haven't run into that much bad advice being spread on hunt-wa specifically, but I have seen websites with some well over specified loads that would wind up with someone being hurt.  If nothing else when giving load advice reference your source I.E. Hornady reloading manual 5th edition or what have you.

I just started reloading my 7mm mag.  There are lots of powders that will work.  H1000 retumbo rl25.  What I am more worried about is seating depth. Trying to get the 168 bergers to group.  They need to be seated further than my mag will hold.
