I have a Cooper rifle in 8mm-06. I like it. I hope to break it in on either bear or moose pretty soon. I used a 35 Whelen for some years and shot several nice bull moose with it. I'm sure the 8mm-06 will be great for moose.
I aerial scouted last evening and counted around 50 bears (all but 3 were black) and 2 bull moose, so I may break it in on a bear!
