Chamber drawings or SAAMI Specs needed

Discussion in 'The Powder Keg' started by Aardvark Kid, Jun 30, 2002.

  1. Help!

    I'm a gunsmith and have been building Mauser based rifles on the new Wincester 300 WSM cartridge; am getting chambers that seem to be too big; cartridges seem to "wobble" 10-20 thou in the chamber. Fired brass is expanding a bunch.

    Using a name brand reamer and reaming the chambers as I do with other calibers; which turn out fine.

    Need to find chamber drawings or specs for this round so I can mic the reamer against specs. Went to the SAAMI site, can't find them there. Any other sources?

    Got two unhappy customers and have two more guns almost finished. Need help before my reputation as a rifle builder goes totally down the toilet!

    Thanks!
