as per the title, I got a 1858 remmy NMA stainless with target sights etc, worked a really nice load for it and worked the trigger now, its a beauty to shoot, but only ever put .454 balls through it, I know that everyone tells me that its supposed to run balls, but being the curious person that I am, I wondered about conicals, anyone tried them, whats the difference in performance if any??

or is there a very good reason for only using balls?
