Hello Guys, got a question!!!!!!! Today I was looking in walmart at their 209 muzzle loading primers and was wandering whats the difference between those primers and the primers for shotshell? They had winchester triple 7's an remington klean bore I think was the name, they said for muzzle loading only. Why? are they hotter and create to much barrel pressure. Could I use the klean bore in the place of the remington sts?
