I have a Charger, and I love it! I put a long eye relief 4x scope of it, and can hit a cat's eye at 25 yards (A figure of speech!!!). Like you said, not everyone's cup of tea, but I like mine. I agree the muzzle jump is an issue, but when the kid runs a mag he doesn't worry about it, and his shots are all in a 4" circle so neither do I.
I bought it because it was different and I had some $$ burning a hole in my pocket from a 30-30 I had that I sold because I have tendenitis in both of my shoulders can not handle high power rifles. I made very good profit on the rifle too, so I have not that much in the Charger. The only issue I have is some FTF with the $40 aftermarket mag I bought that I was told would eliminate the problem. Oh well, I can live with it.
My brother likes it, but he shoots it standing like a regular pistol, mostly because he can shoot it that way just as accurate as me on a bench. Seems he enjoys outshooting me with my guns, but then agian, he did qualify for spot #3 for the Ohio State shootting team when he was in college, but he turned it down.
