In my .50, and .54 sidelocks, I use 90 to 100 grains FFG Goex. I find that going over 100 grains, accuracy diminishes. In my inlines, again, 90 to 100 grains, FFG Goex, or 777, depending on the inline I am shooting. My older inlines, both .50, and .54, Firehawk, and Thunderhawk like 90 grains Goex FFG. My .50 Encore Katahdin, and .50 Omega Dream Season shoot well with 100 grains FFG 777. I have killed deer with all these ML,s except the Omega, which is new. I don't need to pound my body, with "magnum loads", and I get good results with the above loads.
