The thing is, I think one should save one's money for "the best" rifle that IS NOT a semiautomatic .22. I suppose that's why I've never ponied up for the Browning.
"The best" .22 is not a semiautomatic .22. It's also thousands of dollars and it's built, not bought, but be that as it may, semi's are always touchier than manual actions with that little tiny cartridge.
Yeah, the Volquartsen is a DAMN NICE .22! It's very expensive, and it's still a tad clunky. For less money, you can shoot smaller groups at 50 yards with a good bolt gun and you can have a gun that's a helluva lot prettier, or you can have a lot of classy yet down-home style fun with a classic 9422 or 39 lever gun. Anschutz makes some good .22 rifles, too.
A .22LR AR is a really fun, expensive toy, also. The Weatherby Mark XXII is another cool "retro" option, with a classic Weatherby stock in gloss checkered walnut, rosewood, with spacers, and an Anschutz barreled action. Not cheap, but still less than the Volquartsen.
But dollar for dollar, if you want a semiauto that you can let kids use but you'll still enjoy shooting as a grownup, the 60 is hard to beat. Frankly, I wouldn't give a kid the Browning, especially an upgraded variant. Let him/her learn about scratches and dents on something cheaper!
I guess what I'm saying is, tell us how much you want to spend, and what you REALLY want. "The BEST" is just not enough information.
And do you REALLY want a semiauto, when many of us do believe that the most fun, best quality, best accuracy, and best fondling, are found in other types of actions?
