Yesterday was the 1st day of muzzleloading season here in the south. I got to take aim on nice 6 point at 30 yds. or so, and snap cap goes off no bang, put another primer on took aim and snap no bang. I was putting the 3rd primer on when he saw me move and he was gone. Got back to the truck and on the way out of the woods I am thing the nipple has to be stopped up. So I put a brand new hot shot on and primer goes off no bank. I put another primer on and snap the primer goes off then within a half a second or so the gun goes off. I have had this problem before with too much oil in the barrel. So this year before sighting in the rifle I ran a lot of patches through the barrel to make sure of no oil. Then I took some gun scrubber cleaner and sprayed down the barrel and the flash hole. More patches until clean and dry went to load gun and realized I left the balls at home. Two days latter I get back out ready to sight in I load the gun get on the bench and snap cap goes, but no bang. I put a new primer on and the gun goes off with a slight delay. So on Tuesday night I run a bunch of patches down the barrel etc.. I get ready to go in the woods last night I took some brake cleaner that remove all oily residue completely let it dry while I am changing clothes. I run another patch down the barrel snap two primer just to make sure loaded the gun and went in the woods, and no luck. I am shooting a Thompson Center Hawkens 50cal. with Hodgdon Prodex rs, cci no. 11 primers an Hot Shot Nipples. This was the first time I got to go hunting with my gun, and the thing I feared the most happened. Any suggestion in what I am doing wrong would be appreciated there are a couple real nice bucks on our place and don't want this happening again.
