[QUOTE="cantfixstupid, post: 2523117, member: 115328"] I have 257BEE 7.5 twist Bartlein 26" built specifically for the 131 Gr BlackJack Ace. I have shot some 100 Gr factory ammo out of it and does very good, shoots about .75 group at 100. I have some 87 grain factories I am going to try before breaking them down for the brass, I think both 100 Gr and 87 Gr are Nosler bullets. I would go with a 7.5 or an 8 Twist because, if you ever reload for it and want to shoot the heavy Hammer or Berger .257's it will make it possible. I have about 250 rounds down mine now and it just keeps getting better. Went from .325 group at load development to an amazing .210 group and an additional 75 FPS +/- gain and I bet it gets better.
