6ppc and bullet weight

[Travis C.]

Will a 6ppc with a 13/13.5 twist barrel stabilize a 75 grain vmax? Just looking repurposing a barrel and I'd like to run a heavier cheaper bullet and my choices are 13 or 13.5. Thanks

Can't go by me as I do not have enough real life experience, but I am shooting Berger 64.2 grain columns in a 13.5 twist barrel. Their target bullet page shows you should use a 13 twist for their 68 grainers and then a 9 twist for their 90s. They don't show a 75.

The 75 gr. VMax'es measure .942 long (avg). Even in a barrel twisted 1:13 @ 3300 fps, the G.S. will be under 1.0. -Al
