[Rule 303]

Bod, it was with freshly annealed cases and the one of rounds had been in the bottom of the mag for a bit of time while pig shooting. The projectile had worked their way forward and stuck in the lands when I unloaded. So I am thinking too much powder trying to achieve your velocities with ADI powder.

That is the way I have heard of people doing it. Me, being a bit ham-fisted would get a gunsmith/toolmaker/mech engineer to do it.

Gee, rule 303 reducing the expander ball dia is easy spin it in a cordless drill & use 400 grit & finish with 800 or 1000 they are hard but it easy to reduce dia by .001 to .002 inch .

Interesting. I bet one could simply clamp the ball in drill press chuck and take it down a thousandths with fine emery cloth?

That is basically the same way I would do it, but I would put it in the lathe. To take such small amounts of material off and maintian surface finish you cannot use a cutting tool. When I made up the pilots for my Gritter's rod, I turned them within a couple of thou, then hardened them. And got them to final diameter by just running 1000grit emery cloth between my fingers (WD40 lubrication).

rdog you greatly over estimate my abilities. You could give me an A Bomb to play with and when it went Bang a rod with a flag with the word Bang on it would pop out
