First off, I just wanted to thank the moderators and admin for providing such a wonderful site. I have been shooting to 1,000 with a surgeon .308 for a couple of years now fairly heavily and have been competing with said rifle for a while also. I have had great results on whitetail to about 400yds, but want to go further. A new hunting area has opened up 1,000 yard whitetail possibilities. I am going to get a new barrel or barrel/bolt in the near future to get a more competitive edge as well as increase my hunting range, but want to retain the action for a switchbarrel setup. When looking for a replacement for tactical comps I was set on the 6.5x47L running 139s with the promising new RL17 or Norma URP powders. Now that the new hunting grounds have appeared, I am looking at the 7WSM and 162AMAX. The 7WSM has everything that I would ever want ballistically, but at the expense of barrel life, magazine capacity, and powder cost. So now I get to my question: What short action calibers would you consider for wimpy southeastern whitetails up to 1,000yds (providing that good shot placement is neccessary)? Would you feel comfortable with any of the .308 derivatives, or would you step on up to the 7WSM?
