Yesterday I shot my new Remington New Model Army for the first time (See my other post http://www.thehighroad.us/showthread.php?t=414225 here.). My previous cap and ball experience was with my 1860 Colt clone, and I observed that, with a Pyrodex-P load equivalent to 25 grains of BP, the balls were seated WAY DEEPER in the chambers. I normally don't bother with an over-bullet grease, as I often shoot alone in my back yard. But yesterday it was kind of crowded at my club, and if I had a chain-fire I was concerned with hitting the guy at the next bench maybe. So after charging the chambers I filled the remaining space to the top with Crisco.
I noticed when shooting that there were large and visible sparks visible sparks and a substantial cloud of smoke!
Can we call that the "Crisco Effect"?
