Working on tuning the seating depth of my 73 gn Berger bullets and precision bolt loads. After finding the powder load, now even more fun. Loading 6 each .010 jamb, touching, .030 off,.070 off and .110 off per the Berger reloading manual. Looking for that .030 - .040 wide sweet spot and then more refining. This is one of the most enjoyable parts of hand loading for me. Nice part of all this is once you change any variable, it back to the beginning. Whatta Hobby!
