I haven't had a chance to try out my lee 310 PC and GC 44 mag loads out in my 77/44 yet and am working on PCing lee .452 300g for m Ruger American bushmaster. I have been weighing the bullets to match them within 1 grain before loading.
From some one of the posts I've read under 2000-2350fps?
If my rifle can shoot sub MOA to MOA with Jwords can I expect to do the same if I find the correct velocity? From what I've read pushing CB fast opens up grouping?
