I'm not familiar with the New Englander.....are you shooting Patched Ball, Maxi ball or a true civil war style minnie ball?? Your post stated "mini". I too am kinda new and learning this, but I have found with my 1861 Springfield that shoots .58 caliber true "Minnie" balls with the skirt, that the lube that is on the bullet makes a pretty big influence on how many shots you can get off before fouling becomes and big issue. I "dip" lube the bullets in a mix of beeswax/lard/olive oil that's about 4 parts beeswax, 2 parts lard, and 1 part Olive oil.....I melt it in one of those cheap wax melters that the wife uses for the scented wax melts you get at Walmart-mart. then I grab each bullet by it's nose with a pair of pliers and dip it skirt first into the mix, then place it on a piece of wax paper to cool, stiffen up. The lube seems to do a good job of keeping the BP fouling soft, and each successive shot just pushes a good but of the crud down the barrel and on top of the powder charge, where its blown out on firing. I can normally fire about 25-30 rounds and don't really have issue.
