Check out the data for Retumbo and see how it matches


quick load says , 69.0 grains of Retumbo gives 2930FPS 104.5% case fill but a very low psi load . this load gives 47923 psi PMAX and the 7 WSM is rated at 64542 psi PMAX . Retumbo does look like it's close to the AR2225 velocity wise . Jim

    yea i think that will have to be the answer chaps. thanks. im going to fone some people and try get a few mag primers and some ar2217 (h1000)
    on a side not i tried some ar2225 in the .308 and .223. 165 in 308 44 grn 2225 1770fps .223 80vld 18grs 225 1290fps
    could be fun to work up sub loads.
    ps. i have a silencer for .223

    I don't have AR2217 listed either .

    H1000 shows a max load of 71.0 grains 109.3 % case fill ( 63965 psi PMAX) and the velocity is 3121 FPS . hope this helps . Jim
