R.I.P. Scout26
^^^I learn something every day, and I did not know that about 10mm being loaded to .40S&W levels.
Felt ripped off at a range in Henderson when after I rented a 10mm Witness and going through a box of 50 rounds that I thought were very soft shooting for what I had heard 10mm to be like so I looked at the box and the FPS were in the .40 range. But yet I was charged for 10mm. At another range in San Juan Capistrano I tried again and got full-house loads and that was quite the experience. My wife said it was the biggest muzzle-blast of any handgun she'd ever seen me shoot. Fun, but more oomph than I really needed.
I'd have to look it up, but I load 10mm with 180gr XTP bullets on 14.something grains of AA#9, and it's about 1300 fps out of my Glock 20. Yes, that's over the official book max.
