Thread: Testing a conventional approach to load development

Quite surprised theres not much focus on seating depth here. Remember watching a podcast with eric cortina and jack nerry (i think his name was) one f class the other benchrest for team lapua. Talking about seating depth has a direct relation on group size, testing in 3thou increments. A example of this is when people buy factory ammo to test what there rifle likes that is the seating depth of the different ammo that determines the better groups.
I think his way of load development makes sense, first stage over chony, no target to distract you, find lowest es
Once powder charge found on to seating depth testing
