I should have been more clear on usage... I feel I should have a larger caliber available for zombies I guess. IF some issue came up with owning the AR15 (obama), I'd like another option available in the gun safe. It would be used for "fun" shooting really more than anything. The 223 is an option because I've already got ammo for that, so it seems logical.

I don't hunt with guns typically, other than pararie dogs or varmints, small game... (Traditional Archery is my choice for hunting elk/deer) But would be nice to have the larger caliber if things would change in the future for using the bow. (bad shoulders)

I'd probably be happy with either 223 or 308, if I got the 308, I'd sell my SKS, as it's the largest weapon I have... decisions..

thanks for the input so far... Kc.
