well, i started to consider the .223, just for the fact that there is a ton of ammo for them, and every rifle company makes a rifle chambered in it. but, that is almost to much rifle, and i don't handload, i wanna start it, but it might be a while till i do. so i thought about the .221 fireball, and the .222, but, there are few rifles chambered in it. and the ammo is kinda pricy. i kinda like the .221 fireball, but the only rifle i could find chambered in it is a remington, which is fine, but it is kinda expensive. i didn't check NEF yet to see if they have any rifles in that caliber, but i was kinda hoping for a bolt action repeater. i dunno, i might be to picky, but i will look around for a while, i ain't in a big hurry to get one yet. thanks for the help tho.
