300wby loads for 230 hybrids

[Danny1788]

Anyone have any load data for 300wby and 230 hybrids? I'm gonna try them in a factory wby vanguard at max mag coal see if I can get anything good out of them. They are gonna be way in the case but maybe the hybrid ogive will work out.

I doubt you will have much luck with a saami max oal. You could do it like I do my 208amax load, 3.810" 1 in the mag and 1 in the chamber. At that length I settled with 89.2grns of H1000 in wby brass with fed215ms, right at 3k fps from a vanguard. With the hybrid 230s I would start with about 80grns of Retumbo or 78grns of H1000 and work up a half grain at a time, I think 2850fps is doable with Retumbo, I hope you have a muzzle break cause its gonna stomp your ***!
