[QUOTE="Carey Farmer, post: 3099987, member: 122715"] You have to measure the case length at the shoulder with a "bump gauge" and a caliper. Measure before sizing, then size and lightly "bump" the shoulders, then measure again. Adjust your die (or change your shell holder) as needed and try again. Here's a source for bump gauges: [URL]https://www.precisionreloading.com/cart.php#!l=WHID&i=SBG420[/URL] Here's a video on how to set up your die for the bump you are looking for: [MEDIA=youtube]Qd583ZMYncE[/MEDIA] More bump will more reliably ensure that the case doesn't have to be compressed by the bolt to chamber, but at the expense of brass life.
