Been thinking a lot for the last few years about a 221 fireball rifle, something light and easy to carry for a stalking varmint gun and a general plinking rifle. The question is, what platform? A contender carbine comes to mind, and Remington made one on a 700 you can still find. CZ made one on the 527 action, although these are rather rare, and i have seen a few xp 100s converted to rifles. Anyway, what would be the best platform for a 221 fireball as a ligh rifle? Anything I'm not aware of out there?
