7 Stw

[JOSE A. MARINE]

I`m having a new custom 7STW to be delivered next week, and already own several boxes of sierras mk`s in 150 and 168 grains, but the barrel is a hart 1:10 twist, would it be worth trying bergers 180`s?

is the twist too slow for the 180`s?

i am shooting a broughton 1-9 twist in my 7mm wsm. i have shot the 180 bergers and have had no problem, but a 10 twist that might not be enough. berger recamends a 1-9 or faster. have you tried 168 bergers i shot deer at just under 900 last year. it was bang 5 steps and flop.
