[QUOTE="Lefty7mmstw, post: 1107575, member: 48043"] do what my brother is doing and hang an 8" twist pipe (he's going Brux) on your 280ai.... that way you can shoot whatever bullet you want, including the heavy barnes mono and 190-195 grain bullets as they get more common... I put a 8" twist (Shilen Select Match) on my recent 7stw build and I'm still working on heavy bullet loads, but she shoots to 1/4- 1/2 moa with a couple of bullets so far. It seems I've got to go mild with 180's; she won't break below 1/2 moa unless I drop her to 2900 fps or so with what I've tried so far... By the way, a 8" twist seems to work very well with 140's too; the 140 nos bt with rl25 is shooting lights out in the stw... the last 200 yard group I fired (with a egg frying hot barrel) measured .52" ctc... p.s. there was zero load development for the 140 bt load; I had around 400 of them loaded from my old Sendero 7stw. I ditched that rifle 3 years ago... [/QUOTE]
