No, I don't recall ever firing one. I didn't even know Husqvarna made firearms until I came across a 648 owned by a friend, which was later stolen along with that American Arms Double ten I have an eye out for. The only rifles I have ever had much interest in are pre-ban "varmint" guns, lol. I suppose I get that from my military days. I am however hoping to fire one of these long range 50 cal's that a good handfull of makers are selling. I've looked into those quite a bit. They're a bit pricy but I could really get into sitting on a peak on the Montana/Idaho border blasting coyotes from outer space. I know, terrible. But fun no less. Other than that i'm pretty much a shotgun and pistol man. Currently I am watching for a close serial match to my Anaconda .44 mag. I could shoot that thing all day long and never get tired of it. I just love making big holes. I am certainly no gun expert, other than my own guns or guns i've owned. Like yourself however, I have many resources.
