Well.....that's the ultimate "goal" of the entire experiment. I'm not planning on changing OAL, bullet type, powder type, powder charge, or primer. Even the neck tension, as measured by the OD of the neck sized brass (a bit expensive to find the right size bushing. I got it after buying 3 bushings @ $27 per bushing!!!)

And BTW, I DO turn the necks of my brass.
