Home Forums Reloading Big Game Rifles Need a good deer load for 300 WBY

Mine is 24 as well. I seem to get 100fps faster using IMR4350 rather than IMR 7828 in the 24" barrel. Max loads with lighter bullets seem to be with in 50 to 25 fps of the book. (there using 26") and almost 100fps less with 180's

With max loads od IMR7828 it is almost 200fps slower with the 180's
