I have four sidelocks, all Hawken types. One of these is a .58 fullstock, 36" barrelled flintlock of the pattern " thought" to have been made by Jake Hawken before he and Sam moved to St. Louis MO, and started making caplocks for the fur trade. There is certainly nothing wrong with the round ball, and in .58, it should be a real elk stomper!!

Contrary to what a lot of people seem to think, a sidelock type rifle can be made to do anything a " modern" inline design can do, including shooting magnum charges, if one were so inclined. I think a .58 RB at 2000 FPS is magnum enough for anyone.
