I'll be honest, I'm not sure where the best place to put this is, but I'm thinking about looking for a rifle chambered in .221fireball. The way I found out about this round other then on the Internet? I was at a friends place shooting and he pulled out the XP-100 that's chambered in it. Because its a rifle round I was waiting to pull the trigger and have the gun nearly hit me in the face.....it barely moved and I even hit my target. Sadly there was only one round and that was all. So here's my question(s) to you guys, I'm unable to find a box around so and was wondering, what's the range of cost per box(20)? Another question is, do you know of any good rifles chambered for it? All it would be used for is gophers, coyote and of course, paper punching.
