Re-Barreling an M1896 Mauser

BTW: For operations like this, I prefer to turn a rod and leave it chucked until I'm done. My Emco 3-jaw chucks usually stays within .001" TIR, but turning the rod right there and then will eliminate any possible runout caused by the chuck. I use a brass rod, and turn about 1/4" to a diameter that slips into the bore. Then I back off .001", turn another 1/8", back off etc so I get a stepped taper. This will usually get me dead center in the bore.
