Home Forums Hunting & Shooting Ask The Gunwriters Help me understand the relationship between velocity and seating depth

Fifty feet per second difference is within the realm of shot to shot variation for a typical (not great) load. A fouled bore can increase velocity 50 fps. Need to test the load more to see what it averages out to be. Any change in components can do this as well, like a different lot of primers, bullets, powder, cases, etc.
