6x284 mauser

Post by LesWard » Thu Feb 19, 2009 10:27 am

I have a project Mauser, new barreled action that I am going to start
and would like to know the best & safest way to check out the chamber specs. I have had it for 35 yrs. No fire formed brass, so thats out.
I guess I could resize & fireform a few 6.5x284 rounds via reduced load, for measurements.

Any comments welcome.

Aloha, Les

Babbitt the chamber

Put a plug in the forcing cone of the chamber and pour the chamber with babbitt. Tap out the babbitt and the plug and measure it.

If you can't get babbitt, they sometimes used sulfur, but that's messy and besides it's brittle... tends to break up when you tap it out.

Actually even better than babbit is Cerrobend (available from Brownell's.) It melts in boiling water and has well known shrinkage characteristics that can be used for determining the actual dimensions very accurately.

Cerrobend has been used for many, many years.

Yes, Cerrobend, and a little modeling clay for the stopper. Melt over a light bulb.
