I just looked at the Lyman Muzzle Loader book from 2001. They recorded velocities that are close to what I've been getting with similar but not exact loads Most of the industry books dealing with caplock loads indicate maximum charges of 55 grains for the Walker and 45 Grains for the Dragoon models. Others- chiefly magazine writers claim that the Walker will hold 60 grains of Black powder and the Dragoon will hold " a full 50 grains." I'm curious to know if anybody here has a Walker that will actually allow loading 60 grains of black powder (not pyrodex or other substitute) over a ball or a Dragoon that will hold 50 grains and a ball. The ones I handle top out at 55 and 45 respectively and any attempt to load heavier leave ball sticking out of the cylinder-even under maximum crunch. Unless somebody tells me different, I will believe that the gunwriters in question have not actually shot the guns.
