Re: Gun Rebarrel Wich Caliber
If you want accuracy, good bbl life and a 6.5, look at the 6.5-47 Lapua. In a 6mm try the 6 Dasher, or the 6-6.5-47 L. These calibers are really starting to shine in 600 and 1000 BR shooting heavy bullets in a 1-8 twist tube. The F class guys love the 6.5 x 47L. The best part is you can start out with QUALITY brass and they are compeditive to over 3000 rounds. Many, many more for hunting accuracy needs.
Heck, even the strait 6mm BR is raising kane in 600 and 1000 br!!! All have the punch to bring down deer sized game at 500 yards with the heavy bullets.
I also have a 6.5 WSSM, but you need to start out with a mag bolt face. Balistics are on par with the 6.5-284.
