For hunting rifles using less than 40 grs powder I test in 0.2 gr increments. I load up 3-6 start load charge weights and zero with them, than shoot the target 1 each incremental charge weight. I plumb the target, and usually use a 20x scope with .25 moa dot. I'm seating all bullets 0.020 off the lands,or the suggested coal for the specific bullet. Depends on mag length restrictions or previous data for the rifle. I'm measuring the target for minimum vertical dispersion. I like less than 1 bullet diameter vertical in a 0.5 gr range. Than work seating depth. If twist/bullet/powder are working together, sub 1" groups are pretty easy with good barrels. Chronograph is after load development and confirmation testing. I usually can be done in 50 rds. I let barrel cool between shots. 2 shot groups to confirm loads in hunting rifles(because or component availability and cost).[ATTACH=full]8569[/ATTACH]
