A few years ago, I bought a very interesting used rifle. Short action Model 70, with original factory carbine stamped barrel and what appears to be original walnut stock, and what appears to be the original factory engraved bolt with the matching last 4. the interesting part, chabered .257 Kimber (.257-.222 Rem Mag A.I.) and it came with dies. There was never a factory cartridge on that head size in 25 caliber, at least from what I can find. My problem has been that it is a 1-12 twist, so i have been shying away from heavier bullets and working in the 75-90 grain range with zero favorable results, best group being around 2 1/2 inches at 100. I figured before I sell it I would try something a little heavier, so I loaded up some 100 grain NBT's over IMR 4895, and took it out for what I thought would be my last time shooting it before I decided to sell it. the WORST group with this combination was about like the BEST groups had been before. best group with that combo was 1 1/4 at 100, and the rungs of my ladder were pretty far apart, so I think I can get it to do better. This rifle may just belong to my neice for her first deer hunt if I dont get greedy with it!
