Thanks for your input. I have however, decided to use new Nosler 25-06 brass. There's quite a few people who feel this is the easiest route to go based on them having this catridge. One of the most notable I talked to about this was Travis, the owner of RBros rifles. He's built many 6.5-06 AI's and he also felt using 25-06 brass was the easiest. I do have several hundred 270 cases though so if needed I can neck turn them and try them as well. One of the primary factors for me choosing this cartidge over a PRC was the fact I have alot of brass that will work as well as an old 700 30-06 action.
