I wonder why I am the first to comment on RIMFIRES! They are wonderfully cheap to shoot and with the .17 hmr you can do some decent range shooting for the fraction of the cost of some of these others.
I also think that if some of us spent some extra time learning to shoot with our rimfires, it would make us much better shots with everything else we use.
Again, rimfires....revolvers, auto handguns and rifles, bolts, levers, single shots...
