The T/C renagade is a fine rifle, nothing wrong with the 54cal either. Around here they sell for well above $80.00 even with the drilled and tapped barrels.
With a hot shot nipple they will shoot real black, proydex, and T 7 with some care to lay it nipple side down and tap the stock near the tang.
It will handle round ball, conicals and saboted bullets equally well with the right load of powder.
