Awesome!! Still working on bow season here, but I'll be taking my flintlock out for the rest of rifle + muzzleloader. Got a coyote with it last year when it was 10F outside, but no deer. This was the only pic I got (the rifle did much better in the cold than the camera battery).
I haven't had any moisture problems. My frizzen makes a good tight fit over the pan though; I keep it under a greased calves knee in the rain and replace the priming every 30min if it wet out (2hrs or so if it's nice). It goes bang 9 times out of 10.
