Hello, I'm new to muzzleloading. I just got a T/C Triumph. I ordered some Thor bullets, so I could use the same bullets for whitetail that I use in Colorado someday for elk. I went to the range for the first time yesterday. They first two shots went well, but then after that I had 3 misfires. The primer went off. The bullet went 10 yards and the Blackhorn 209 barely sprayed out of the barrel. I swapped between shots. I also cleaned out the breach plug after the first misfire. I got the sample size kit from Thor last year. The .500 was loose, but the .501 was tight. The .501 was so tight that it was hard to get in and out, so I went with the .500. I'm wondering if it is too loose??? I'm pretty sure that I was getting the bullet seated all the way down by the firmness and the length of the ramrod. It did got in easy though. The power was brand new and I just broke the seal on it yesterday. I'm using CCI 209 mag primers. I was trying to shoot 110 by volume blackhorn. The Thor bullet was 247 grain hollow point. What am I missing here??? If it is the loose bullet, can anyone recomend another bullet for this gun? Thanks for helping a newbie!
