What is the best load for your traditional with a 1in48 twist? In a .50 Caliber side lock muzzle loader a traditional load would be a 370 grain maxi ball with 80 grains of FFG black or pyrodex powder. A modern 250 grain shock wave bullet in a sabot with the same powder charge is very accurate as well. In a .54 caliber a 430 grain maxi ball with 90 grains of the same powder would be a recommended load.
