Cap locks are a pita.
Will shoot mine tomorrow, but look forward to a good flint rifle Bob Elka is building. Saw it Saturday at MAAC, complete enough to hold & pull the trigger. Small Siler with brass plate Frederick Sell style, 38" .45 cal swamped Green Mountain barrel. Light enough for even my decrepit old body to hold.
No more fumbling for & dropping those @!*% little caps!
Remove that d--- overhung drum & replace with a stainless, or Ampco 45, vent. Get a real fire lock.
And no, I am NOT opinionated.
Yeah, I used to build rifles but let my skills fade. Built one Sell w a 14" barrel.
