I have been playing with the Primal Rights CPS primer seating tool. Conditions where not ideal this morning but I wanted to run the test at 1k. Even though the conditions where not very good, in my opinion the results certainly tell me primer seating depth does matter. I shot this with my 6BRA with a BR4 primer. Group size was effected as well as point of impact. Each .002" increment was worth about 1.5-2" in poi. I measured the pocket depth and the primer height to determine the "crush". .004" and .006" overlapped and held 2.7" of vertical for all 6 shots. We will continue to work on this and will share more as we learn it.
