I dont recommend other than full bore bullets for such cartridges, it may work in BPE barrels but the snider isn't in this class. When I get a cape gun with a full rifled 28 bore a Lee 585 Minie, 480 grain mould laying around here. the 40mm long case hold 100 grain Wasag blackpowder and I get a strong cartridge with a NDFS 577 snider die set. But also with this Minie bullet it shoots not realy good. the barrel was very good with a .605 groove dia.. Make a hammer swage die and rework the minie's to groove diameter, it shoots allways better.
If you playing around with your dies you will be able to set any bullet. oversized lead bullets can be set with this die and run then a second time in the resizing die, without decaping pin. this reduce the bullet diameter inside of the case and make a "heeled bullet".
old german cartridges like 9,3x72 R or 8,15x46R hade allways have a stopring bullet. that means a oversized driving band sit 's on the top of the grease grooves. the CIP list show this for the 9,3x72R: common bullet diameter is .364 but the list have a max bullet diameter of .376" - yes this is true.
Nowbody ever load a .376 bullet in the 9,3x72R, this was the max. dia. of the driving band from lead bullets.
BTW this helps allso by loading ammo with simple handload tools because the driving band sit on the case mouth and give a uniform length of all cartridges.
