Re: Lost in the woods re: GA, WY bullet selection
What you need is a bullet that will shoot one inch groups at one hundred yards and has a weight over 140 grains. The higher the BC the better but at ranges of 400 yards it is not so critical as the accuracy. A bullet in the 150-160 range is adequate for mule deer.
If you are buying factory ammo your only choice is to test different ones and see which ones are accurate.
