    Start with a .264. You can later try a .263 and a .265 for experimenting with neck tension. VV133 likes lots of neck tension.

    I use a .265 with my .269 neck. So with your .268, .264 should be about right.

    My loaded rounds measure .267..

    What I like

    with a .270 NK chamber is .266 loaded round and size with a .264 bushing. This is with VV133
    Had good results with this.

    The old standby answer is a bushing .002” smaller than your loaded round diameter. That said it doesn’t hurt to try tighter than what is normally recommended. The bushing I’ve been using for the past several years is .005” smaller than my loaded round neck diameter. I am using boat tail bullets.
