The last .300WSM I loaded for pushes a 200.20x @ 2916 from a 22" barreled Tikka LA w. The HCA WSM mags.Do you actually own and a shoot a 300WSM? The case volume isn't enough to push heavy bullets. Anything over 180 gr. becomes horibly slow. To the poster I tried about 10 differrent powders in the 165 to 175 grain bullets. The slowest powder was reloader 23. Things like Superformance, ramshot hunter, 4000 -MR, Leverrevolution, and hybrid 100. You are never going to get speed with powders as fast as Varget. You have to chrono your rounds because load data listings are often optimistic.
I also loaded a 20" .300WSM pushing 215 Hybs @ 2800 in a true R700 SA length action as a repeater.
Would you consider these "horribly slow"?
