[QUOTE="VinceMule, post: 3074414, member: 122164"] Hunting Hard, I hope you read Phil Rizzo's response, much insight for you there. I would bump the shoulder back on the tight brass, not sweat it at all. You maybe over reacting to what you think is a bad thing, when it is actually a blessing. I would much rather have a chamber that is a tad short vs one that is long where the brass headspace is going to expand .006-.012 upon firing(belted mags), The reason is case stretch. I like my cases to have minumum stretch in the chamber, which can leade to longer case life, especially when firing warm loads near the top of the pressure curve. Whether it is the brass Headspace that is longer or a chamber headspace that is shorter, does not matter, you can make a "custom" fit easily which is to your GREAT advantage. When I am forming wild cats, I set the headspace where I have slight resistance in closing the bolt, and I keep the bolt lugs greased every 25 rounds so they do not gaul. So, by setting the headspace on the wild cat chamber so it will have minimal case stretch, the brass lasts many, many firings, if I keep the necks annealed. Best of luck! [/QUOTE]
