I found a Remington CDL SF 260 Rem New in Box. I am a fan of 6.5mm. This is a limited edition rifle. My question is the quality of this gun as I have read some not so great reviews on Remington lately. The second question is the twist rate of the barrel. All the other 6.5mm guns I own have a 1/8 twist but this gun has 1/9. Will the 1/9 stabilize a 140 grain bullet?
