The 8 mm with multiple lube grooves is a loverrin,(SP?). style. They work too. I just finished sizing some 45/70 420 bullets that use wide, shallow lube grooves. Lubing both grooves uses 1.9 grains of lube!
That should be plenty to let the bullet slide down the bore. Modern lube works better with less than the old bear tallow used on the black powder bullets.

They're going to get their butts kicked over there this election. How come people can't spell and use words correctly?
