Have you tested it with anything as of yet?  Most of those should work, but you will need to see just how much chamber support you have for the Underwood, Buffalo Bore and Double Tap.   if the chamber is well supported you should be fine with those as well.

What magazines are you using with your AR?  Converted? or Olympic Arms molded?

I recently purchased the rifle on Gunbroker, it came with 3 Olympic Arms Magazine AR-15 10mm Auto 18-Round Polymer Black. I ordered 3 more from Midway USA. Right that are on backorder. The only rounds I have shot are Remington UMC Ammunition 10mm Auto 180 Grain Full Metal Jacket cycled thru without any jams or misfires.  I am planning to use it hunting hogs!

Thanks for your input, I'll repost when I get a chance to try some different types of ammo.
