I'm shooting Kyle's bullets out of mine it's a savage model 10 action that Jeff at Hankins Custom Rifles barreled the action for me and put in his breech plug.These guns are awesome I'm pushing a 325 gr right at 2900fps.
After i burn this one I'll order a 7 exit twist from rock creek of I like the way it does.My brother is shooting a 257 stw we put together and we've had good luck with it.He just hunts with it so barrel life it's to much of a concern for him I will shoot mine more.
I'm thinking about having a 30" 1 in 8 twist 6.5 barrel I have rechambered in 6.5 stw to try some of the heavier bullets coming out.Anybody shooting one?
