It depends on what you want to use the gun for. If you want to hunt squirrels and rabbits, or target shoot, size is not an issue You want one of the larger .22's Like a Buckmark are one of the Mark II Rugers. However, if you are like me and frequently go out to the barn to dispatch trapped 'coons, opossums, etc., the new Ruger SC22 looks like it would be better in that role. Or, if you carry it while hiking, or hunting but not as your primary, the SC22 may be a better choice.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill? (Exodus 22:18)
