BigBear -- I have your event on my calendar and am planning on supporting. NRA-certified as rifle instructor and CRSO although I prefer instruction to RSO.

As said in another thread, I have a number of target quality bolt-action .22s we can use for this including one with a scope zeroed for 100 yards -- but only have a couple mats. All of them have aperture rear sights, most of them have aperture front sights (some of the Mossbergs have front blades). The one catch is that I don't want just any ammo run through these. CCI or Federal are okay but I have plenty of Aguila ammo that we can use if that's an issue. I've already had one instance of having to replace a bolt due to Remington Thunderbolt ammo and it's hard to find parts for these.

Will try to give you an exact inventory and maybe even some pictures tonight.
