In my quick search on the subject it would seem that it is legal to hunt in Texas with any centerfire caliber (no rimfire).
As to the ak, I have two sons who would probably agree with you (Damn black ops) but, not really interested. I was thinking of a Mini 30 tactical but, Im not even sure they make them anymore (cant find one anywhere).
So no one for the Ruger Gunsite? Im thinking for the money a DPMS ar10 (I know thats not the real name but, it should be) or maybe a FNAR would be money better spent?
I like the 308 round (from what Ive read) and can buy the reloads from freedom muntions pretty cheap.
Oh well, Im going to the Pasadena Gun show this weekend. So I have no doubt Ill forget most of the advice and make an impulse buy.
Seriously though I appreciate all the advice.
