I worked a ladder test at 200 yds this past saturday. I only did to rounds of the ladder test. Remington brass (from corlokts) CCI LRP 4831sc 130gr NBT I believe i have a node between 58-60gr. What is the next step? Do i work another ladder with smaller increments between 58-60gr or do i do the OCW test now? or do i just shoot for groups?
