This is number 8721 in my book of excuses for missing the target. I've fitted a 7mm drill bit on a rod to clean out the gunk in the chamber every ten shots or so. It's quite suprising how much builds up in there quite quickly, changing the size of the chamber, (number 8722). Maybe the filler helps. The bloke Tac mentioned who shoots rather well for Pedersoli uses an equal measure of filler to BP.

Added to the above, I've never had a patch burn through while using filler.
Actually, he shoots very well for the Hungarian national muzzle-loading team, using Pedersoli products.

The reduced-sized chamber of the Pedersoli pistol is called either a Patent or High Pressure breech, and is commonly found in ML target rifles of the day.
