Just looking at John Alexander's post on no bullet lube shooting without leading. My coating using the tumble lube method is undetectable and seems to work well. I would be interested if John progresses to GC bullet velocities and what the results might be. Just wondering if there is much difference in the friction of an un lubed bullet versus a epoxy coated bullet? I just may try some un lubed bullets in a rifle or two.
