I agree with this...The fact is, the .308 and 30-06 are very close in performance. If you are confident with your 30-06 for your hunting needs, then you'll likely be just fine with the .308 too.Bowie said:A .308 will be fine for moose at any distance a sane person should be shooting at them from. While gunnuts like to debate specific cartridge choices, consider that most opinions are formed from one or two examples (if you are lucky) and contain many variables.
This said, it is my opinion that there is little practical difference between common hunting rounds, providing a properly constructed bullet is used, and shot placement is there.
BTW, most 300 yard shots I have witnessed have paced out at more like 180.
