My 1st smoke pole was a CVA side lock. Haven't used it in years,but did have couple misfires using #11 caps and the factory nipple. Had somebody way back tell me put a hot shot nipple in the gun,buy a nipple pick, and always but always fire 1-2 caps after cleaning. I followed his advice and never had another misfire.Now I have a T/C using musket caps and a Knight using 209's. I always fire 1-2 caps in either of those inlines. It makes me feel warm and cozy. I sleep much better the night before a hunt knowing I fired those caps.

I don't ever need to wonder if gun might hangfire while looking thru scope at that prize buck. Seems like cheap insurance to me.
