A woods walk set up for wounded vets, with EASY TO SEE / EASY TO HEAR, reactive targets, on a finely graveled path that can be accessed by a TrackChair, motorized, tracked, wheelchair
Along with half a dozen, inexpensive, loaner, T/C Renegade rifles in .50 caliber. Have the steel buttplates removed, and install Kick-eez Magnum recoil pads. Find patched ball barrels if possible. Have some of the "Lock Meisters" here tune up 6 of the L & R replacement flintlocks for the T/C. Install those locks in the Renegade rifles, and put a White Lightnin' touch hole liner in the barrel.
Then reach out to wounded vets at the VA, American Legion, etc. that would like to shoot a muzzleloader, but otherwise do not have the means.
See if TrackChair will help with sponsorship.
I'll throw in a $100.00 to help if you can pull it off.
