I guess for the reasons that I decided to use
traditional sidelocks I'd want to stay with the traditional #11 type nipple & cap.
Used to use Pyrodex RS and select, but once I switched to Goex, there's no going back...real blackpowder is so fast it's instantaneous.
So I eliminate any ignition concerns by just using real blackpowder and always start a hunt with a fresh powder charge.
To me, using a modern, unnatural ignition source would defeat my whole purpose of buying a tradtional muzzleloader in the first place.
And a #11 cap sets off Goex blackpowder so fast
it's like shooting a .30-30 as it is, so I can't imagine it going off any faster...just my opinion
based upon personal experience
