Re: 300wby loads for 230 hybrids
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 *****!
