I missed the best 8 point I have ever seen night before last. I'm sure it is because of blowback fouling the firing pin, hammer and trigger. It was very cold, perhaps 10 above. I had fired the huntsman a half dozen times the week before rifle season, around the 10th or so of November to check scope, etc. I then cleaned it, ran Gun Scrubber through the frame, worked the action repeatedly, dried it, gave it a light oil spray, wiped it and put it up.
The firing pin only dimpled the primer. Of course, when I got back to the barn and emptied it, It fired just fine. I took the quick and dirty way out. I put it on a clean shotgun frame and will deal with it in 3 days when the season's over.
I still have time to hunt, and perhaps I'll get him yet.
