Sharps Model 1863 carbine

[Eric Johanen]

I don't know. May have something to do with placed flat against the base of the case or around the circumference of the chamber walls. With the base of the paper cartridge exposed there is a lot of powder to flash along the paper and it seems to burn it all up. I do have a question, why would the ash left in the case be a problem? It all is removed on cleaning right? (confession, I still have not got around to trying a coffee filter paper under powder wad). I'll give it a try come spring when the weather is better. I do use a under primer wad of about .004 with Federal Large Pistol primers for some loads and because the Federal's are just a bit snugger to seat then the other brands have not seen any evidence of gas leakage or breech block peening. I only use the Federal brand for this application. Beat the cold today at an indoor range and a .223 carbine. Feeling very good!
