Sammi specs went out the window once I got my guage. Trim only to uniform all my brass. With my factory chamber, I'll never reach max length anyways. I load a lot of the light and shorter stuff, so any extra brass I can safely use, is a bonus. I consider the 7 bucks for the plug, a great reassurance tool to have.
Sinclair recommends .024 from max chamber length. From the many reads I've came across on this subject, guy's are using a whole lot tighter tolerance's then that. Some up to .005. That's only the thickness of an avg. beer can. I would consider .010 to .015 as my min. To each his own.

I'm not real sure if I may be reading to much into this statement....... But, everytime I've taken this measurement, each reading was exactly the same. If you have to take an average
of your reading's, you may have another issue.
