[QUOTE="brian11, post: 1895413, member: 112031"] I'm using 270 brass for my AI chamber. Not only is 30-06 brass more work & trouble, it also comes out a tad short after the shoulder gets puffed out. I size the neck diameter, then trim to 2.522 length, which will barely fit in the chamber. When I fireform it, I lose about 10 thou in length, which ends up being perfect for what I want. If you're not using AI, 30-06 or 25-06 would be fine. Of the three cases, I believe 25-06 is generally the least commonly available and most expensive, although not by a lot. So, to answer the OP, AI is a bit more work, and probably should be done with 270 cases only, while the non-AI is a bit less work and can use any of the 3 cases, probably 25-06 being the easiest, as no length trimming needed. Thus far in my load development, I'm not even filling non-AI cases, so being AI is not a gain for me, at least not yet. I've only just begun my load development, although I now have 100 fully formed cases. I found that, even during fireforming, accuracy is excellent. [/QUOTE]
