[QUOTE="Bullmark, post: 2132104, member: 113003"] I had a .280ai built and used a Bartlein 1/8.7 twist.....I thought it was an odd number. After 40-45 rounds it’s shooting 168 VLDs into one big hole if I do my job. But initially we tried 140s and it didn’t group nearly as well. So I’m not sure if the rifle didn’t like them or if they would have tightened up after more shots. For record I’m using 57.0 gr of H4350......which doesn’t get mentioned as much a few others as the go-to powder for .280ai. I’m getting 2950fps out of a 24” barrel with low low ES and .25” groups, and extremely light recoil....so I’m afraid to tinker with anything. [/QUOTE]
