Yeah RockFish, mine is a Zoli too. I shot some Minnie ballsout of mine once but they were too small for the bore and not very accurate. Mine shoots round ballswell enough that I never bothered to search for the right Minnie. Balls are a heck of a lot cheaper, and as sabotloader will tell you - I'm cheap.

You got an excellent buy with that gun Rafsob. Your load is a little on the light side but obviously great for 50 yard targets. The service load for a 400 grainMinnie ball in the Zouave was 60 grains FFg and a muzzle velocity around 750 fps. My chart doesn't go down to 40 grains, butshows a 50 grain load of FFg yields 680 fps under a 400 grain Minnie.

The twist rate in mine is 1:62.
