Lyman (not Hornady) great plains bullet. 450grain flat nosed maxi in .54 cal, over powder wad. Very impressive.
I have both barrels for my GPR, one 1:32 twist for maxis, the other 1:66 twist for roundballs (cast 0.535) . The whole lot pulls apart and stores nicely in a short case. Perfect for travel.
