Reloading Question
I am having to use BR-2 large rifle primers on my 22-250 reloads.
I have been putting 39.2 grains of H380 under a 53GR Barnes TSX FB.
The Barnes book says you can go over this charge a little because of the ring lands groves in the bullet.
My question is ,
Do you think I should back off a few tenths of a grain to offset the large rifle primer?

Yesterday I was playing with my 257 Roberts that I've had some accuracy problems with. I loaded up 3 rounds using 35 grains of Varget and a 115 gr Nosler B.T. The OAL was 2.920". This group of 3 averaged about 7/8" at 100 yards. I loaded up 3 more with the same powder and charge, except this time I made the OAL 2.900 and the grouping opened up to about 6". My question is, can .020" make that big of a difference in accuracy? Next question is, how good of a bullet is the Nosler B.T. on deer? I heard it said once that they have too thin a jacket to get adequate penetration, and my final question is, on bullets with a cannelure, such as the Speer Grand Slam, is it necessary to seat the bullet so the cannelure is at the rim of the case? 0 -
Red, both 30/06 and russian 7.62x54R are true 30 caliber(.308) according to my Hornady Manual. Just use the correct load data for from a 30/06 manual. I would start with the lightest powder charge listed and work up slowly from there. I don't care much for the copper plated, steel jacketed bullets that a lot of the russian cartridges use but that is just me trying to protect my bores. 0 -
They tend to run .310 in diameter (as oposed to .308 for the -06) so for liability reasions I'd say no.
Can they be used? Well some people have fired oversize bullets, and if the loads are on the mild side it would probably work.*
* before I get jumped on answer this. Why are factory 8mm Mauser loads (.323 diameter bullets) so mild? So they can be safely fired thru the origional .318 bores.
Some guys like a mag full of lead, I still prefer one round to the head.0 -
Red, after I read tailgunners answer I realized I was guility of jumping the gun a little. I have not miked any of the russian bullets, and if they do mike .310 as tailgunner says, PLEASE, dis-regard my earlier advice. By all means, mike the pulled russian bullets first, and the if they mike .310 I would NOT LOAD THEM. As tailgunner said, you might get away with shoving a larger projectical down a small diameter barrel--but then again you may not. The real question is --buying the proper bullets or taking a chance on my eye sight or worse. 0 -
Why are you wanting to do it? 0 -
From what I've read Russian 7.62 varies from .308 to .310 and may not have a problem in an old shot out 30-06 barrel.
I have a bunch of Czech corrosive ammo that I'm pulling the bullets for my 30-06 for an upcoming appliance shoot.
The Czech ammo has done nasty things to one of my M91's. I swore it was clean but apparently not neutralized as the entire barrel was rusted inside...She cleaned up though and was one of my poorer condition M91's anyways.
I like throwing things with steel in it down range, especially old lawn mowers.0 -
Regarding the shooting of larger than bore size projectiles: Why don't you read (all of you) the chapter in P.O. Ackley book, I can't remember whether #1 or #2, about his tests on shootong 8mm bullets through 30 cal barrel. I find it rather interesting.

I have read Ackley, which is why I put in the qualifier that I did. However if the peak pressure and the swedging occure at the same time, or if your seating to be tight aganst the lands, you can have troubles. Another consideration is the neck diameter of the chamber and bullet release, in a factory chamber slightly OS isn't usualy a problem but in a "tight neck" chamber bullet pinch can rear it's ugly head, Ackly had his chamber necks reamed out for his experiments. As I don't know who else might be reading this thread, and just how much of a differance in diameters they (others, not Red223)are going to try using, I left my answer somewhat generic.
Parker wrote that back in the days when people took responsability for there own actions, not like today where no matter how foolish the person is it's someone elses fault they got hurt.

Why go to all of that work?
You like to blast appliances, lawn mowers, etc. so take the rifle that already has had a bit of a problem ... blast away, clean with warm soapy water followed by regular clean and lube and be done w/ it.
More time for "blastin" that way.
If you only have time to do two things so-so, or one thing well ... do the one thing!0 -
I've both read and talked to Parker on several subjects, probably before some who are reding these statements was born. I too try to always err on the side of safety. The last two posts by Tailgunner, and Contender Man are on the button. Why even bother if the benefits "might" be outwieighed by the potential problems. 0 -
Well Contender my Remington semi with a 10 rounder is more fun than the bolt action M91 for spraying appliances.
I'd rather shove a softpoint back into the 7.62x54 and is it for Muley's and whitetail.0
