Welcome. I'm all the way up in Sandpoint, ID, but lots of stuff goes on in the southern portion of the state. I can't name any off hand, but if you search rendezvous and Idaho a bunch of stuff comes up, especially since the Oregon Trail goes through the lower portion of the state.
We have idaho free trappers rendevous monthy in cascade, they also shoot monthly in nampa at g and b ready mix gravel pit by invitation.
There's malheur trappersin vale oregon..
Both are on facebook.
We also shoot ML 12 shots, out to 100 yds on mini pepper poppers, and 100 yd gongs, BP Percussion (cival war type pistols) pistol 6 shots at pig target 10 yds, and 6 shots at pig target with BP Cartridge pistols (modern ok).
I would have to get $800 out of it. I can also include about 50 lead balls with it. It hasn’t been fired much at all so it’s in really good shape. If you’re serious about it I could make a trip up your way because it’s really not that far from me I’m in Blackfoot Idaho which is right outside of Pocatello.
