These are being used in a P80 G20, but with a G40 length threaded barrel from KKM, and a 12.5" DI AR15 upper.

The .45ACP was traveling at about 852fps.

I need to try a heavier recoil spring in my 10mm.  It slings brass into the next county.

I bought the largest tarp Home Depot sold:


And I still had to adjust where I stood to get the 10mm brass to stay on the tarp.

Good news for me… https://www.ar15.com/media/mediaFiles/369122/C5AE3E3D-7985-4F65-A000-C9DFF06F1764_jpe-3239164.JPG

I have plenty of Blue Dot, Long Shot, Power Pistol, and some Acurrate #whatever powder.

My one 650 is set up for .40 right now (and small primers) .  My other 650 is set up for .223 right  now (and also small primers).  Decisions….decisions….

There's a lot of weak 10mm factory ammo out there as you found. You just have to know what you are buying. It's the same for 45 acp though. A lot of it is to the old 1911 standard of 230gr at 830 fps. But if you look it's not that hard to find different stuff. For 10mm the Federal 200gr HST load is pretty solid. The Underwood 220gr FN round is about as powerful as it gets. For 45 acp, the Hornady 230gr XTP +p is pretty strong. The Buffalo bore 255gr FN aint playing around at nearly 1000 fps.
