Memphis, I shoot with the same club as Drydock. Strictly at our club level, we have added an extra class for Military. Basically anything GAF goes, I have shot a Krag, Trapdoor, Moisin Nagant, Lebel, Argentine Mauser, Swede Mauser, and a GEW88.(I think that covers it) The Trapdoor is loaded to the "carbine load", 45-55-405, and hasn't damaged any of our targets(Although it has knocked a few over) Smokeless rifle rounds are loaded to SASS specs, lead bullets at under 1300.
That being said, since you don't belong to any clubs yet, I'd just go shoot you choice of lever guns while wearing your uniform to get started.
