[QUOTE="Mikecr, post: 2636676, member: 1521"] For basic reloaders to consider: If you're trimming to book value (arbitrary to chamber), or visual (go/no-go), then that's one part of your reloading that's weak. It is basic, and safe, but it's stronger to tie [U]all[/U] your methods to measure. All actions to plan. That's just a suggestion. There is another way to watch for a trim length problem. I do it by habit, as my trim length provides very low clearance. When a case mouth hits chamber end, that mouth is shiny where contact occurred. I can also feel it. As I eject each round (I pick them from single shot actions, with eject-delete), I automatically feel the case mouth, and the primer. If I feel anything I look close. There have been occasions where I ran out of clearance, and when I see a shiny spot on a case mouth I STOP. No more shooting until I've put calipers on those cases to find out what I have. Maybe I had just annealed the batch, or maybe I'm getting too lazy on the bench. Something has changed. Of course this is not something to rely on to tell you it's time to trim. But it's one of the things you can be watching about your brass -while firing. [/QUOTE]
