I'm reloading for a Winchester model 70 featherweight in 270 Win with Norma brass and Federal 210 primers. The rifle has had the lugs lapped, the barrel hand lapped and the action trued. The barrel is free floating and I've played with the torque on the receiver screws. I've double checked the scope base screws and the scope ring screws. I've heard a few times that the factory barrel on a featherweight doesn't shoot very well. I've found that the barrel shoots A LOT BETTER warm than cold. I've tried Barnes 130 grain TTSX, Nosler 130 grain Partitions and Nosler 130 grain Accubonds. I've tried H4831SC, H4350 and IMR 4350 powders. The groups are usually 1" to 1 3/4", sometimes as small as 5/8", but not consistently. Any suggestions on which bullets to try next??? I want to use the rifle for whitetail hunting, so terminal performance is important along with accuracy. I'd like to find something that would shoot 3/4" or less at 100 yards.
