[QUOTE="MagnumManiac, post: 2458236, member: 10755"] I know this for sure when using fast twist barrels….the smaller the bore, the less number of grooves and the smoothness of those lands/grooves will show up a bullet that is either, too fragile, or has voids or other imperfections like an unevenly thick/thin jacket. I had serious problems with a 3 groove 22 cal barrel with a 7” twist…it was NOT the barrel causing the issue per se’, but the entire package, the barrel, number of grooves and the bullet used. Switching bullets cured the issue…so, the choice is yours, run a fast twist but choose components that are compatible with each other. I have seen very few issues with twist rate once you get in 6.5mm territory, but it does still happen with CERTAIN fragile bullets. Cheers. [/QUOTE]
