Thread: 260 Rem, AI & Imp

Just that wee bit more capacity without getting up to a 284 case. Although it does need a med length action. Would probably send you 140's out at 3000fps

Yep had one on a Turkish Mauser build, thumbhole stock and 28 inch barrel got it shortened to 24" then had to fire form cases a lot of fluffing around for no real world gain. @Tahr's 6.5x55 with 20" barrel was quicker. I was getting around 3000fps with 130 grain projectiles. A 6.5x284 would be a better build idea.

My barrel is 21" and velocity is 2830fps with 140 Amax. N560 powder.
