257 Roy with zero freebore = 100g at 3850 shooting sub 3/8" groups with 100g within 30 rounds fired with R#22. Stuff is just dead, very dead on bullet impact = ZERO runners, I do not know how to stress this fact enough. Old tec rules in this case.
I actually got 1/2" groups with 100g partitions.
If you feel like a wild man, go 6.5-257 Weatherby AI. 120's at 3600 is normal. PTG has the reamer. All I care about is accuracy, and stuff not running off.
