BTW, no supersonic rounds yet. Still using the Wally Mart Crosmans. It's just quite a bit louder than my 10/22 with a Thompson Zephyr prototype. And I'm spoiled by it. And my Trail is just the NP, not the NP II. I did that on purpose, to avoid going supersonic. The whole idea was to try to shoot like a suppressed .22 powderburner, but with less expensive ammo, and to try to duplicate the accuracy.
