RE: Addition to the battery.
Yeah,I have a .223 and that gun is very fun to shoot. Cheap and fun. A box of 20 costs less than $7 anywhere you can find them. Lots of times I find them for around $5 a box. Mild recoil, long distance, good accuracy and the capability to take down game up to about 75 pounds pretty easily. Also a pretty good range of ammo. Other than that I guess that a good shotgun would maybe be a better choice. Maybe a Remington 870 in 12 or 20 gauge.
