Just dialed-in my brand new Winchester M70 FWT in .30-06. So far I've determined that it doesn't like two things: (1) Federal Fusion ammo (165 gr. Hornady SST seems to have worked the best so far) and (2) a hot barrel. No kidding guys, if that thing's even remotely warm, you're probably going to get a stray round (by about 1-2 MOA).
Has anyone shot better groups (i.e. sub 0.65") with 150 gr. rounds? If so, what type?
