[QUOTE="Barrelnut, post: 2496273, member: 74902"] Well, one thing a RUM is kinda know for is extraction issues..... I have a Sako extractor and it always pulls the fired case out but it can get real tuff sometimes. The main issue is that the specs for the RUM chamber are tight. If you have a tight spec chamber, after three or 4 firings and resizing of the brass the case web has expanded to where it gets hard to chamber and extract. It's really a situation where you need a small base die to get the web back down. You can measure the web area with a micrometer and see the issue. Different brass effects it too. Nosler brass has a larger diameter at the web than some others and will stick on me after 2 firings. [/QUOTE]
