I live in GA and hunt whitetail inside 200 yards, but I'm going to WY to hunt mule deer and want a bullet that will shoot accurately to 300 - 400 yards in my Kimber 7mm-08. I have been shooting Federal BT and Partitions, HSM vld Berger bullet and Hornady SST with some accuracy. What bullet would you recommend? Need different bullet for each location? I'm feeling lost at this point and need someone with more experience than me to weigh in. Thanks.
