There is a good amount of AI brass available but there are a number of superior case designs which bring the efficiency of AI into play without being AI. An example is the 30TC, it will give you 30-06 velocity in a short action and is a very accurate round, wish I'd never sold mine. All of the Sherman's are great, as much as folks love to rag on the 6.5 Creedmoor, no one can honestly deny its capability in any "practical" application for that bullet size. As heavier for caliber bullets continue to emerge, the Sherman's capability will allow one to make full use of those bullets. Someone will likely make a 200 gr. .264 with a crazy b.c. that will only be practical in a single shot short action or a modified long action large capacity case to achieve velocities necessary to stabilize such a long bullet. For me, I believe in practical simplicity, my grandfather killed everything in north america from moose to bear and deer with a 30-30 he bought new in 1900 and never thought twice about it not being enough gun. I've been reloading since the mid 70's and I do it because I like little groups. Bullet placement means more than any other factor, nothing else matters as much.
