OK, how about some myth busting.
Does anyone have a force gauge/measuring equipment to measure the difference in resizing force between unlubed and lubed 9mm cases using Lee carbide resizing die and Lee progressive press (PM sent to OP to ask whether press in question is Pro 1000 vs Load Master).
I would do the testing but lack the proper equipment to do the measuring. And to ensure consistency, verified once-fired brass from the same factory box would need to be used.
Since I made the claim residual polymer on brass surface from tumbling with NuFinish polish decreased the amount of resizing force, it would be nice to add NuFinish tumbled brass in addition to bare and lubed cases.
Anyone up for this challenge?
I am curious what the actual numbers would be.
I've been thinking about trying exactly what you suggest. What got me thinking about it was that just last night I resized and primed a bunch of brass, some of it was brass that I had wet tumbled with Armor All Wash-n-wax, the rest was wet tumbled with Dawn. I could definitely tell a difference. I was thinking of a way to measure, I may just try to use a spring fish scale.
