this is a shooter!!i've never shot a flintlock before today,or real black powder either.this is just fun.my first 3 shots using 90gr.goex 2f under a .020 pillow tick patch lubed with lehigh valley patch lube and a .495 speer rb was a 4" horz. string centered on the bull.this was standing but resting the fore stock on a window sill at the camp.then i started shooting offhand and kept most inside the previous group.i then switched to 90gr.goex 3f and again used a front rest.this seemed to shrink delay time and the horz.stringing,this also raised poi about 1".in the pan i was using goex 4f with a little tc pan priming flask.on the lock a german agate.if i learned anything today it was rocklocks are fun and to order more round balls..........karl
