I got a 22-243 on a trade it has a 1-8" twist 26in barrel so I am looking for some load info for the 75gr Amax. I have almost 8lbs of imr4350 anyone using this with good accuracy?
Ended up loading some RL22 in it over the weekend 43gr to 45gr. Groups were not bad around .75 moa speed was low 45gr gave 3420 ave and es of 27 not great but I loaded up 45.5gr to 47gr today will shoot tomorrow and get some pics up.
I shoot a 22-243Middlested, slightly less case capacity with a different 62 grain bullet and 47.X grains of H4831. I get a little over 3800fps with excellent accuracy. Just curious? BB
