Yes, I just txted the seller and it's an 8. That's exactly what I wanted. To be able to shoot the heaviest projectiles. Thanks you good bastards.

If you have an unbalanced wheel on your car you will not feel the vibration at 40 but it will be shaking the steering wheel at 100. The same with jacket runout on a projectile. You increase rpm with velocity and fast twist rates. All things being equal a 1:12 will shoot better groups with a 55 grain pill than a 1:8. This is why PPC shooters use slow twist in their barrels to shoot groups.
