[QUOTE="357Mag, post: 1525141, member: 106883"] Kobra- Howdy ! I know this is an older post, but wanted to mention... In " AI " cartridges, case capacity increase does not come via sharpening of the shoulder angle. That step in and of itself reduces case capacity ( esp when powder will not be positioned within the neck ). It's the " blowing out " of the case' shoulder diam ( for example... when part of an AI case forming process ) that provides the case capacity increase over and above the stock configuration. Combining the two steps should result in some case capacity increase, the amount of which varies w/ the differing cases involved. With regards, 357Mag [/QUOTE]
