That Gunblast writeup was pretty good. 1150 rounds in 3 hours without cleaning! Heck, I've owned 2- .22 LR revolvers, a S&W 617 and a Rossi 511, neither would go more than a couple hundred rounds before they got so dirty you couldn't even chamber a round. Maybe the .22 Mag burns hotter/cleaner.
Pretty interesting visual on the video of Jeff shooting 3 LCR's in: .22 LR, .22 Mag, and .38 Special. Didn't realize a .38 bucks like that in comparison!
