Saw a deal on another forum that had a link to Winchesters new 2013 rimfire. A .17 Win Super Magnum. Shoots a 20 or 25 grain bullet at over 3000 fps. They say it will be comparable to a centerfire! Anyways, a round like this will sure open up more hunting on areas that are open to rimfire only. Sure wish they would hurry up and let out what rifle it will be on and it browning will be making a rifle for that caliber as well.
