I've got a reasonable outfit, more than needed for open but not for the costume categories. I'll call that good though comments when I show up will be appreciated.
I have purchased (check will go out within a couple days, then bank delays, then FFLs) a pair of revolvers. They will come with belt, holsters, and a bandoleer. Will have to see if they fit.
Separately, on speculation the above is good and works, I ordered ammo for the revolvers.
No cowboy legal rifle (partial to 1873 but willing to try others), no cowboy shotgun* (partial to hammerless SxS but willing to try others. My lady has a cheap game-legal SxS but getting it open is a real pain (needs slicking). I can bring that with me and I will have to look if my shotgun shells are legal for your range.
I do see a trio of '97s for sale (from months ago on this site). My lady got excited when I showed her the post. She shoots too. I have not shot a '97. I would love to try one.
While I took the alias John Kloehr, I am not bound to follow history exactly; I don't even look like him LOL. And for my outfit, I played with how Hollywood might have outfitted him even though I am not trying to enter a costume class. I have read John Kloehr used an 1873 octagon barreled rifle in 44-40. I have no documentation yet on any revolvers (found one reference to him at least having one) or if he even had a shotgun.
So help in any of the above areas would be great. And if no loaners work out, I'm happy to just work with what I have and have fun and learn.
