I have not shot any thing bigger then a coyote with a .223 and doubt I will as I have a 30-06 and a .338 Winny. If I lived in the "lower 48" maybe I would, maybe not as I believe there are better choices for me.

As to being big enough for deer and antelope, I think it has been proven to work, but not my first choice.

Now please don't call me a liar gents, but I know one guy in my town that took a .338 Mag. bullet through the chest, don't know the bullet type. The guy was drunk and pissed off a home owner who shot him in his drive way. Never knocked him off his feet, but he did lay down and wait for the ambulance, eventually the shooter did a small amount of time. Both of them were in a prison I worked at. The exit hole was about the size of a golf ball and all healed up by the time I got to look at it. A .223 at the same distance may of killed the guy, go figure.

I have been using a .338 Winny since 1975 and have never had to shoot any thing more then once!
