Care to fill us in on the "big changes" you speak of ?? Other than the KDF&WR's survey awhile back that reaked of "trophy buck" mentality ... I haven't heard of anything of any certainty. Generally speaking on the 223 subject ... can't see it being specific just for this one caliber. There's a whole slew of like centerfires and smaller that are legal under the no minimum "any centerfire" regs at present. Which personally I have no issue with 223. The AR platform alone is such an adaptable platform for anyone especially kids. Now would it be my choice to use for deer... probably not... I've got better choices. Which in the bigger picture I'm doubtful that the 223 accounts for any more wounded deer than any other caliber or method. Just boils down to a piss poor shot is a piss poor shot. Unfortunately you can't regulate common sense & ethics no matter what restrictions / rules in place.
