(posted for folks who have faster twist than a factory 7mag)


Nosler use 9.0" twist for their test rifle and 175 LRAB.
Barnes recommend minimum 8.0" for their mono-metal 175


What B.C. values are you using? The Nosler web site has corrected values of .546 and .616 respectively for the 150g and 168g LRAB. I used the corrected values.

Coyote Hunter - NRA Patriot Life, NRA Whittington Center Life, GOA, DAD - and I VOTE!

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
