    Spritzed with a little lube and the boat tail survived.

    You converted them to flat base slicks. What's your next trick?

    Very cool. Way to stick at it.

    I was surprised they survived without ripping the plating off. This was going from .316" down to .309" in one shot.

    My camera must be really **** good too. If you were looking at these with the naked eye, the sized area looks like glass copper. Camera sure does bring out the minor defects.

    I went ahead and sized 3 more without lube, 5 total and 9 others were lubed. I loaded them all up and will test sometime this weekend if not before if the weather cooperates.

    How thick of a coating were you applying, lefty o? The way I see, and lack of better way to describe it, is I am only putting a condom on these bullets and hoping it doesn't break. I really think the better way to go, if feasible is to start with a .277" bullet and find a way to get .035" coating on it and then size it down to .309". Figuring out how to do that is going to be the problem. I guess I should ask too is how long did you leave the barrels in your bath?
    it all depends we had stuff that was thin, and stuff that was thick all depending on the application. we plated anything from 1hr up to 16hrs. curious what you are using as your copper source?

    I don't do plating but looking into wet PC. It appears that a minimum current is needed to activate, above that current is dependent on surface area of plated items. The actual plating voltage requirred is ~ 1.5 VDC but higher is needed to overcome the resitance of electrodes and solution. Kinda sounds like the TSP is providing a coating over the lead which is more conducive to plating.
    from Wiki - "The flux(sic TSP) is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing. Residues are water-soluble".
    Whatever!

    A roll of 1/4" copper tubing I picked up from Lowes. I have it sitting directly below the bowl. It is still wound in a circle with one end sticking up out of the bath that the positive wire is hooked to.
