My first muzzleloader is the lyman great plains rifle . 32 inch barrel 1:60 twist . . Just got a traditions mountain rifle . 32 inch barrel 1:48 twist . Goex ffg powder , paper patch ball . Any magic number on the powder ? I been told from 90 to 120 grains . I will play with it on the range but just curious what is popular preference . Would triple f be better ?
