22's
High end: S&W mdl 41 w/ heavy brl., High Standard Citation series, anything from Jim Clark Custom Guns.
Low end: Ruger MKII (steel frame), Browning Buckmark Field Target.
Optics such as Red Dots should be kept LOW to the brl, so get a good mount like 'Jack Weigand'. JW is on the net. There are only 2 red dots IMHO: Tasco Pro Point & Ultra Dot. The Buckmark does not become off balance with a dot added due to it's alloy frame. Others become heavy and muzzle heavy without some pricey custom work. Some models are trickier than others to add a dot and keep the 'feel' right. The Norinco TT-Olympia can also be a good gun, but they are a hit or miss as far as quality. They are also difficult to find. I had one that was a dog. The one I currently own is a keeper. It will shoot on the level of my High Standard and that's saying something. Try to find a 22 Bullseye match close to you when you get set up. I think you'll find it interesting and fun. A High Master can put 10 shots in a dime at 50 feet with a one hand grip. Good luck.
