I used to hunt in Maryland and was talking to an older hunter that had a .30 carbine. He said it worked for him. I would not want to use a .30 carbine but don't think twice about my .223 0r 22 Hi-power. I did not stand in the woods and argue with him about his favorite rifle because I never used one. When I was a kid I was convinced a .243 was too light for deer. That was from listening to older guys that never used one. I have used all kinds of calibers over the years and now I can barely remember the time I had to blood trail one. When I was younger I listened to the same nonsense about shooting deer in the "vitals" from older guys. I now use mostly lighter calibers and hit them in the neck,shoulder or head. Yes, I said head.
Of all the different rounds I have used to shoot them in the so called "vitals", the 7-30 Waters is probably the one that made me track the farthest. I would definitely take a .22 center fire over that. I hunt public land, and usually in two states. My buddies and I have dropped a lot of deer that were already hit near the vitals(Within a 16" radius). Some are hit in such weird places we can't figure out what was being aimed at. Some of my friends are magnum fans, but I don't preach to them, as they seem to do O.K.
