6 mm Remington -The Hodgdon site shows 47.5 gr. as MAX for 7828 with a 100 gr. bullet and a compressed load at that. Be careful trying to work up to 49 gr.357mag, thanks for the info. My Hornady load book lists 49.0 gr as max load @ 3000FPS. A friend of mine has a few pounds and is going to let me try some to see how it shoots in my rifle. If it works out I’ll buy the rest from him.
