[QUOTE="varmintH8R, post: 871983, member: 39801"] I bump shoulders 2thou every time I reload, as I don't like the idea of doing something different every "x" time I reload. Also, as per AZ's point it gives you some tolerance on a hunting rifle (you go to jack round #2 in for a follow up shot and the bolt won't close = major bummer). As far as measuring bump, research and buy a headspace gauge kit. Typically they clamp on to your caliper and give you a reading to a datum point on the shoulder. I have a Hornady kit, it isn't NASA type equipment but it gets the job done. I think Sinclair makes one too. Measure a fired case, and adjust your die down SLOWLY until you get a measurement 2 thou below that. Then you are set up. Just that easy. [/QUOTE]
