I'll toss in my 2 cents as well to stay with the .243 Win. Great cartridge! I have several and have always loved the cal...and it's also what I chose for my daughters first cal.

That being said...AI's are cool and having a wildcat in the cabinet it always cool. If you are looking for a reason to buy an AI...then do it. Just be aware the limited benefits will come at a hefty price, one I say isn't worth it just for a 'yote gun. But again..I secretly want an AI in my safe as well (257 Bob AI maybe...or maybe even a 243 AI??) just because.

I would also recommend what someone else did as well...consider the 243 WSSM. Pretty dang close stats with the 243 AI and at a reduced cost over the AI. I have a 25 WSSM and am thoroughly impressed...and the supper short action is very nice when cycling the bolt on the field (especially over a long action).
