I am hoping to be able to hit the paper at 800-1000 yds with the Hornady 75gr A-Max. and would appreciate any recommendations on primer / powder. The 10FP has a 1 in 9 twist and 24 in barrel. I have been doing OK with a 69 gr Sierra HPBT Varget powder and the CCI BR4's but the load will not stay supersonic beyond 6-700yds.......
Thanks
