[QUOTE="ATH, post: 1023909, member: 1656"] Thanks for the PM. I've read from a couple sources that an AI chamber should be set 0.006" shorter than a standard chamber, which is why standard cases end up "crush fit". I have standard 243 cases and a standard 243 GO gauge. I read of a few gunsmiths using standard gauge then setting back 0.006". I have no idea how to do this with my equipment, which is why I was hoping to add a formed AI case into the mix of tools to use in confirming headspace. They sell 243AI headspace gauges...figure there is a reason?? Don't know, just learning. I can see how, theoretically, changing the shoulder angle would change how the gauge fit by a few thousandths.
