Well, I had some 10g shells several months ago, but sent them to my brother as he's the only one I know that has a 10g anymore. Wish I had one of them now. Nevertheless, what a seriously cool project. Best of luck and I can't wait to see them all put together in a display.

In that lot I also received some IMI black tip and blue tip 9mm, an aluminum .410, and a .30-30 Accelerator.
I also got a couple of weird ones, a .30-40 Krag case cut down below to bottleneck and stuffed with a .44ish bullet, and a .25-20 Single Shot necked down to .22. Any ideas?
Edit: It looks like the .22 wildcat is a predecessor to .22 Hornet, called .22 Harwood Hornet which was initially loaded with black powder.
Hey bushmaster, where is it you are located. I saw you don't have a 6.5 Grendel on the list. depending where you were I have no problem just giving one for the display. I also didn't see 9mm Makarov or .30 carbine on your list.
