Having difficulty shooting my T/C High Plains Sporter sidelock. What a great little gun if I could get it to shoot consistantly. I can fire two or three shots before I have a hang-fire/mis-fire then have to pull the bullet with the dreaded ball puller. I keep it real clean, have gone to the larger musket caps thinking it was a primer problem, used both 777 pellets and loose powder, all with the same problems. Any suggestions? Should I send it back to T/C?
