I've narrowed it down to 2 calibers, the 30-06 or the 7 mm rem mag. Need some input from expierenced shooters. This rifle will be used as a all around gun to hunt all north american non dangerous game, mainly mule deer, elk, black bear, whitetail, and caribou. What is the barrel life between the calibers? How does the trajectery work for actual shooting? How about shooting groups between the 2? On game performance on actual kills, does one out weigh the other as far as harder hitting? I've checked the ballisic tables, I would like to here from someone with hands on info. Any and all info is welcomed.
