I have been out of shooting for about 10 years and am getting back in.
I had a 'groundhog gun' made back then in 6mm Ackley Improved, Rem 700 action, 26.5 inch, 1:14 twist Rob McLellan barrel with a .266 neck in a HS precision stock.

My loads back then were 52.0 gr of IMR4831 under a 70 gr Nosler BT or Berger, which gave 3850 fps and 1/2" @ 200 yds on a good day.

I have all my reloading equipment and wondered if someone would be good enough to give me some advice on what improvements have been made in the last 10 years and what I should try as far as bullets and/or powder, any help would be appreciated.

Thanks,
Dan
 
Dan, if you haven't already check out Forums on 6mmBR.com. There's a lot of variations
on the 6mm, powders and bullets nowadays and there's a lot of good info there.
 
I am using R22 with a Berger 88 grain VLD flat base (varmint).
I shoot them around 3450 ish and have been able to shoot sub MOA groups out to 1200. Yards.

P.m. Me for the charge weights etc.
Its a great caliber! But the throats errode faster than I would like.
 
I agree with DT. Nothing wrong with what the 4831 gives you but if you want to experiment I'd look at RL22. I shoot a 6-284 which is a little bit different case but it and
the 6AI are pretty equal in velocity and I use RL22. I'd also look at some of the 4350 powders.
 
Thanks much for the help, I'll try the RL22 and 4350 and see if 75gr VMAx bullets will stabilize.

No real need for improvement like Jeff270 says, but it gives me something to do.
