Hey guys, Just curious if the 30cal, 240gr Matchking is twist specific. I think Sierra says it needs a different twist than a 1 in 10. Any info or advice would be appreciated.

It depends on the MV. A program I have, Load From a Disk says at 2940 fps and up it needs a 10 twist, 3528 (rev/sec). 2930 fps and below needs a 9 twist, 3906 (rev/sec). That is what this program sayes, but if I remember correctly some have found the 10 twist at even lower MV to still work for them.

I have a friend that lives up your way in Palmer. Haven't talked to her in a while but I assume she is still there.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
