The Pedersoli is a decent gun, but if you search, an old Zoli can shoot just as well at a much lower cost.
Since I shoot minies in competition, let's review what it takes to get a minie shooting well-
1 real lead minie
2 sized to .001 under bore size you may need a sizer die
3 know ACTUAL bore size, not what you think or what somebody said, measure it
4 use real black powder, 2 or 3f, I prefer Swiss
5 use good caps- RWS or Schuetzen
6 use natural based lube like lard, tallow or crisco
It's really as simple as these steps. If you must purchase minies, the ONLY source I trust is Lodgewood. PRB places like Track and others are centered around PRB and are not minie experts. I have seen bullets from online sources that "said" they were pure, but were hard, like 8Brn hard and those will never, ever shoot well. My guess is wheel weight scrap used in those. Molds- just cuz Lee is cheap, don't assume it will shoot in your gun. I have only one Lee mold that shoots acceptably. If you're going to cast, get it hot, pour it fast and you'll have less trouble in casting. A rough bore isn't necessarily going to preclude shooting an original. You will however, have to clean and wipe it between shots. If the bore is in decent shape, a well balanced minie load can be run till you run out of ammo, shoulder or daylight.
Molds- I highly recommend that the new minie shooter not purchase a mold right off. Get an assortment of minies from Lodgewood to test first and find what bullet design shoots best following the steps I've outlined, then buy that mold. It will save you lots of headache and money.
Get it right and a minie can be very accurate-
