Semi auto loads and bolt action loads are very different in my Sierra manual. Max for H335 for semi is 25.7gr.@3000fps for 55gr.
Max for H335 for bolt is 27.5gr.@3300fps for 55gr. The test rifle for the semi is a colt AR with 20'' HBAR. The test rifle for the bolt gun is Remongton 600 with 24'' barrel. My manual doesnt list v-max bullets. I dont know why those other manuals list such low powder charges. If anything I thought my sierra manual is very conservative.
