Snag all three basic Mosins, the M38 carbine, the M44 carbine with attachted pigsticker, and the 91/30 rifle. They are still dirt cheap for excellent examples, and a lot of fun. As gas prices drive everything up, now is the time, well, actually, last week was the time, but get them while you can, and a couple of cases of cheap ammo.
Fun, accurate, and a "blast"!
