Re: Bryan Litz joins Berger Bullets
Jon,
1:10" is actually pretty fast for a .338.
Consider the twist required to stabilize the heaviest bullets for smaller calibers.
(These are approximate numbers)
.224" caliber 80-90 grain bullets: 1:7.5"
.244" caliber 115 grain bullets: 1:8.0"
.264" caliber 140 grain bullets: 1:8.5"
.284" caliber 180 grain bullets: 1:9.0"
.308" caliber 240 grain bullets: 1:10"
.338" caliber 300 grain bullets: ;)
See the trend? 1:10" is pretty quick for .338; you can stabilize a lot of bullet.
Good luck with your new build,
-Bryan
