I am hearing a TON of good stuff about the new .204 caliber. I'd like to get some more info on it. Does anybody know what gun makers sell a .204?

At BassPro the other day I saw a nice one, I believe it was made by Browning, but not sure. The bolt felt real good, and it was relatively small size gave it a great overall feel. It was selling for about $565, anybody know?

Thanks!
