The Henry Big Boy is allowed for most SASS classes, only exception I can think of is Classic Cowboy, wich requires an 1873 or earlier design. Main problem is, they often don't work that well when you try to work them fast. If you have an NCOWS club nearby, then they won't work for that, since they aren't a copy of anything from the pre-1900 time period. I'd say, since you have it, and like it, head on out to yuour local SASS club and proceed to have some fun with it, before deciding to rush out and buy another rifle. While you're there, you can look at, and maybe try out, other guns and see what you really like best!
