Time to get back to work after a long Winter! First barrel cut and beginning to turn down. I cut through the cartridge neck about half of its length. I plan to drill the monoblock out to 3/4" and turn the barrel down accordingly. I had a cheap set of drills and quickly dulled the next drill up from the 5/8th's I started with. Due to its limited capacity of my 7 x 10 lathe, I used the 3 jaw with the chamber threads to start with, and now have my 4 jaw chuck installed for final facing, fine turning and will 'short chamber' leaving .005+ for final reaming.......at least that's the plan for today! This should leave a final barrel length of 23 1/2".
