[QUOTE="J E Custom, post: 1422647, member: 2736"] I dont single anyone out when we have a discussion if at all possible. I was just commenting on what I know after chambering many AIs in all calibers. I have always followed PO Ackley's recommendations and have never looked back. The results have always been steller. When nosler first came out with the "New" 280 AI SAMME cartridge, I was still chambering the Ackley method. and was perplexed by the changes they had made in the original 280 AI cartridge so I talked to dave kiff about it and he explained the hole deal. (There is a post on this site that he did on this subject that explains it in his words) He built the reamers for Nosler and discovered that the reamer drawings had been altered after some of his clients started having trouble with case head separation. I don't know if it was his fault or nosler had it changed for their own reasons (I don't care) but i was glad to learn about the difference before I used the new AI headspace gauge. I have since done both chamber and haven't had problems as long as the correct brass is used for ether. This picture posted by another member shows the difference between the original 243 and the 243 AI case and clearly shows the recommended .004 thousandths crush fit of the AI chamber. [/QUOTE]
