i own both a traditions flintlock and a bpi cascade which is a magnum. i shoot 90 grains with a patched ball from the flintlock and 100 grains with a lighter (140) sabot or power belt from the inline. i would like to load magnum in the inline but im not sure of the protocall. can i use 150 of the pellets, 150 of loose, do i have to use the special "magnum" pellets? whats with the imr pellets? any info would be great

thats a 240 load
