338 1:10 twist

Will a 1:10 twist stabilize the 300gr smk and why is everyone using 1:9.3 twist?

    I've had two different edges w/10 twist barrels they both shot them good. I'd imagine everyones going to the faster twist for the wildcat bullets.

    Re: 338 1:10 twist

    The 1 in 10 twist is the best all round twist for 200 gr to 300 grain bullets, But if you are
    only going to shoot 300 grain bullets then the 1 in 9.2 ,9.25 or 9.5 would 'probably" be
    better. (No proof of that just a hunch)>

    If you are planning to build a monster 338 (Excalibur or bigger the fast twist is not nessary).

    With a .338 Edge or similar I think you will have no problems out to 1500 yards with a 1 : 10 twist and the 300gn SMK.

    We use a 1:10 on a 338 Lapua using 300grn SMK's. No problems with stabilization so far. I know it is not a far shot, but I picked an empty shotgun shell off of a backstop this past weekend at 100yrds through the middle dead center with the described rifle and bullet above.

    This is only my opinion so take it with a grain of salt but I wonder how much of this 9.2, 9.3, 9.whatever stuff comes from some of these computer software programs that you input the information and it calculates "the perfect" twist rate.

    I am always open for something better but when you have guys like Shawn Carlock, Kirby Allen and Dan Lilja all saying 1-10, well, that's good enough for me.
