Re: Lighter Bullets, Fast Twists and Ballistic Coefficients
For Longrange hunting, the twist that is RECOMMENDED for the heavier and higher BC is the one I use.
In the big 22s --22/284---22/6mm IMP Etc. 8 twist and 80 gr match bullets.
6 mm such as 6/06--6/284--6/Ackley--8 twist and 107 gr to 115gr match bullets.
6.5/284--6.5/06--6.5 Gibbs--264 Mag --6.5/300 Weatherby--Etc---8 twist and 140 to 155 gr MK bullets.
300 win, 300 Weatherby, really any 30 cal imp with a large case design-- 10 twist with bullets up to 220 gr match. Some barrel makers say a 9 twist for the 240 gr but, the 10 twist works just fine.
My 338/416 Imp has a 10 twist and I use the 300 gr bullet.
I would hunt with the SAME bullet I would use at longrange even if a close shot presented itself.
Of course I recommend a Match King and the heavier ones in the caliber you are shooting.
The higest BC in the MK, I have found to work the best in any caliber I shoot..
Good luck and Good shooting.
