I've only had my XCR to the range a couple of times, but when I get it there I find myself pulling the trigger pretty quick. Well, I maybe even fill the air with lead. Pelicans, seagulls and small aircraft scatter for cover. Hell, if I had wanted a single shot, I would have bought one. I've also learned, the hard way, that the barrel can get real hot. Even a klutz like me can lay down effective fire 50-100yds at a rate of 40-50rds per minute. Somebody who knows what they're doing is, I'm sure, much faster. Question: How fast, how long, can you fire one of these things before the barrel does the viagra droop?
