How much variation in seating pressure have you found to be acceptable without negativity effecting the group?Not to change the story, but instead of weighing primers, try measuring your bullet seating pressures.... this will definitely tighten those groups up.

I try to keep them sorted by 5psi, With about 10 psi differences I see no difference in group sizes. Now when you start talking 15-20 psi differences you will see your groups open up. This is just my experiences.How much variation in seating pressure have you found to be acceptable without negativity effecting the group?
