Wrong bullet weights, IMO. For competition given you have a quality 1/7 twist don't make much sense not to shoot the bullets best fitted to your rifle barrel.

Why give up wind drift ya don't have to......

Suspect the 77grn SMK will be your best choice in the Krieger and Midway USA sells the BH bluebox 77 for a decent price.

YMMV, but my list is short here: there's BH which you have listed and then there's Federal Gold Medal 77grn SMKs.

What distance and type of competition? That makes a huge difference in your choices.

This is for a practical rifle competition and ranges run anywhere from cqb on one stage to 8" flashers at 250yds, possibly stretched out to 300 soon. I'm doing ok now, with about 2-3moa Q3131 and 62gr WWB but wanted to narrow it down some for to increase my hits at the LR targets.
I can shoot, there is no doubt about that, I know the rifle is capable of it as well. I'm not expecting one hole groups as it's wearing a TA31A on it now, but I would like to find a load that will cut that figure in half.



Anything under 200 - and I'd say you could use 52gr HPBT's which would be a much cheaper load. They will still cut your numbers in half from milsurp given those requirements, but the 68/69gr loads will buck the wind a bit better.

I think you are on the right track. While I agree - for your 1:7 twist barrel, the 77SMK's are nice - I dont think this is the application where they will be required. You are looking for ammo that will increase hit potential on a 8" target at 250yds. Given that's your longest shot... and 2MOA will get you there, I'd say looking at the BH in 52, 68, or 69 will do fine. 52 of course is the cheapest.

I wont shoot Ultramax... too spotty a reputation.

Georgia Arms 68's would likely be an excellent candidate for this... if economy is important.
