i think your gun is about 15 years old or so.i have one called a plainshunter that is similar with the exception of double set triggers.i am positive you will be fine with a 60-80 grain powder charge.i shoot my patched round balls using 80 grains of 777.normally you never charge a caplock with any more than 100 grains of powder unless stated on firearm.i do know that any more it is hard to burn all powder.if you have never shot black powder cap locks b-4 you might want to ask the procedure. old semperfi
