I trim only as needed, have Lee cartridge specific e-zee trim and a RCBS. Trim my AR brass with the Lee everything else with the green machine. The Lee trims to minimum no adjustments. I don't trim brass for bolt guns, or custom chambered rifles with it and those are cut .005 short of the chamber cut #. I have no small base die, haven't needed it even shooting 20 practical formed from once fired LC brass. Some of the 20p brass I have sized and loaded 3 times. I have been using plain chap stick(experiment) for case lube, haven't had any issues. The chap stick rinces off case with hot water and a couple drops of Dawn. Had a SS tumbler for 2 years haven't open the box, still using a little simple green,vinegar and hot water. Swoosh a couple minutes(after decapping) rinse with hot water,dry,lube,size.
