It let up after 20 minutes. I made a big mistake and paid for it with the scope to the nose deal My first shot was obviously 80gr Pyrodex P, next shot i held the rifle loose and holy cow, that was a hot 90gr Pyrodex P load and the scope smacked me right in the nose and left a pretty good gouge in it. I am taking 3 more shots, 1 80gr charge and 2 90gr charges to get a complete group of 6 shots total.

I'll never do that again!
