I'm not new to muzzleloaders always used flintlocks. So I'm now getting into percussion. 3 times now with 2 different rifles I've had a problem. I will snap a cap before I load and then load. I will go to fire and nothing happens. 2 or 3 caps later still nothing. Usually ends up with me pulling the nipple and dribbling a little powder in and it goes off. After it shoots I have no issues with firing. What am I doing wrong? I'm thinking I have to much oil in the barrel but I don't use a lot.
