You know we talk about the caliber we use or like and someone always has something either good or bad about that particuler caliber. But you know they are all good, within their paramiters.
I read the book about Frank Glasser, "Alaska's Wolfman". Frank was a Market Huntier, a Meat Hunter for the road commission, Guide, Wildlife Collector for the USGS, and Government Preditor Control Agent. Frank lived in the wilderness, camping most of the time. Walking or riding dog sled across much of Alaska. Frank was able to buy the latest and greatest in firearms and scopes of the day.
Only one time in the book did Frank say he was undergunned. Frank tried to kill a Grizzly with a .220 Swift. Frank was hard pressed keeping a tree between himself and said Grizzly, as he kept shooting it every chance he got.
Now thinking about what I shoot most of the time, Foxes, Lynx, Coyotes, Wolves, Caribou, Moose, and Bears. I usually carry three guns with me when I go out. .17HMR, .223, and the old 30-06.
Foxes, .17 HMR works good. Small hole in and no exit hole. Can shoot them out to 200 yards no problem. A .223 blows them in half, same for the Lynx.
Coyotes, a .17HMR just does not stop them, a .223 works good and puts them down in their tracks. A 30-06 is kind of distructive.
Wolves, the .223 is minimum, sometimes it will stop them and sometimes it won't. I have found the 30-06 is a much better choice.
Caribou Moose and bears, 30-06 is the minimum. Yes I could kill Caribou and Moose with smaller guns, but what am I going to do when I run into a Grizzly. I don't care what anybody says about this or that gun will kill a Grizzly, I will not face one with anything smaller than the old 30-06.
