Did you add a zero? After owning several dozen different manufacturers, from hi-standard model B's through Model 41s I've never had a 22lr be able to go even 1000 rounds without being "gummy"After 1000+- rounds mine got a bit jammy with a couple of brands. Guess I should clean it.
Gotta say my Buckmark usually goes 3000 - 5000 before it need a cleaning. ;-)
My most reliable suppressor host to date only gets around 500 rounds unsurpressed and maybe half that suppressed-
