I think I may done something pretty stupid. I picked this gun up at a local pawn shop without doing any research on it before hand. I figured $500 for a Win Model 70 in what appeared to be "new" condition with a scope would be a steal. I was so wrong! The first 2 boxes of commercial Winchester ammo (100 grs) and several boxes of reloads using 90 gr. Nosler BT's over various weights of IMR 4350 and IMR 4831 have me feeling like I may have picked up my first Winchester lemon. The best I've come up with so far is a 4 inch group (all other 5 round groups had at least one round jump out to 8 inches) with 43.5 grs. of IMR 4350. If anyone has developed a decent load (2" or better groups @ 100 yds) for one of these guns I would really appreciate your help. As of right now I'm just about ready to trade this thing for an old Remington 700 in 243 or send it back to Winchester to see if they can get it to shoot straight. Thanks for your help!
