Well, we DO have a black powder and muzzleloader section.
In case you were not sure, ANTIQUE has a specific legal meaning with firearms. An ANTIQUE firearm is either made prior to 1899, OR is a caplock, flintlock, matchlock etc that uses loose powder and ball, no matter when it was made. So a Winchester Model 94, MADE in 1896 is an antique. Same rifle made in 1910, NOT.
