T/C Hawkins and Renegades, in both .50 and .54 caliber were designed to shoot Maxi-Ball projectiles. I have a Renegade in .54 and it shoots fantastic with 100 grains loose Pyrodex RS and T/C Maxi-Hunter bullets over a wonder wad. I have killed too many deer to count with this combo. It shoots patched round balls just as well and I killed a double one day with full penetration through both deer standing broadside. The T/C Hawkin and Renegade are some of the best black powder rifles ever sold.
