What's the ideal trimmed length of a cartridge, relative to the actual chamber length?

[QUOTE="MagnumManiac, post: 1638389, member: 10755"] I measure my chambers and trim to .015" below that number. The only time I trim to SAAMI is when a chamber is short. Most reamers, whether SAAMI spec or not, have .030" - .040" clearance cut into them as a safety feature. I have a 25-06 chamber that is barely .020" over minimum SAAMI cartridge length, that is .010" over trim-to length. This caused me some problems prior to measuring the chamber. I would say .010" clearance is absolute minimum and .015" is absolute maximum for me. Cheers. [/QUOTE]
