I,m a newbe ,bout 10yrs,major problems when i started,now have 4 flinters,because of this forum problems are almost gone,touch hole ,min. .062",my tulle is .072",pan polished mirror smooth,i,ll repolish once in a while,frizzen cleaned with alcohol ,not your thumb, bevel down on flints seem to work better for me,flints wrapped in lead or leather,leadseems to work better,but a couple guys here kinda scared me so only one of my guns uses lead,tap barrel when pouring powder down,a couple kernels should go into pan,if not clean touch hole, i over sharpen my flints,as i mostly hunt i use a brand new flint every time,half cock flint should almost touch frizzen, oh yeh,i,ll wet an dry patch every couple shots then pick touch hole ,target shooting ,sorry darryl can,t seem to go multiply shots without cleaning,i hope this helps
