I have a Traditions Frontier 50 cal sidelock and the powder well hole in the breachplug is very small in diameter which may be unique to only my rifle. I was using CCI #11 mag caps.
When I switched from pyrodex to triple seven FFG I still had hangfires. Triple seven FFFG solved the hangfire problem maybe because it is very fine and made it down the small powder well hole.
To me the following makes no sense but may help someone who has a similar problem: I tried Remington #10 caps (they did fit much tighter)and am now able to use triple seven FFG with no ignition problems.
