When I've looked online to see what's available for .36 caliber and .44 caliber lead free balls, nothing really shows up. Does anything exist for cap and ball? I've been thinking after doing my rifle build that I may get a Uberti cap and ball 1851 Navy .36 caliber just to have one to shoot every once in a while. Been a cartridge shooter my whole life, so cap and ball is new to me. It seems like finding lead is getting harder and harder. Just wondering if anything exists that doesn't harm the pistol at all.
