I like the Berger method for rough tuning COAL. You can load the depth test bullets, pressure test bullets, and charge test bullets at home just leave those at maximum length and use a Lee handloader to seat the pre loaded charge test bullets to the best COAL at the range. Saves the hassle of powder measuring at the range
I sometimes do a second tune on COAL working my way in and out from the best in .003 incs to fine tune. You can tune groups horizontally and vertically with practice
