wildcat 6mm-257 weatherby mag

I shoot a 25/300 Wby Mag with a 1 - 8 twist 26 inch barrel and have shot Hornady Vmax 75 gr and Sierra 100 gr Spitzer. The 75 gr over 4100 fps but don't shoot worth a crap. The 100 gr at 3800 fps and shoot really good.

My brother used to have a 6-284 with a 1-8 twist barrel and it would make any J-4 jacketed bullet blow up over about 3300 fps.
He had to use Sierras to go over that speed because they have a tougher jacket that holds up better.
This was before Lapuas were available here, they are supposed to be a strong design as well.
You will most likely need to slow down velocity, or switch bullets to make your setup work

I shoot 55gr Sierra Blitzking out of my 6MM AI and 50gr Sierra Blitzking out of my 22-6MM AI. And they hold together great. They are really good Coyote bullets. And have shot the 50gr over 4400 fps.
