Crimp Start adjustment: This is an up or down adjustment. Adjusting the amount of crimp start will control the “hole” in
the center of the loaded round. Too little crimp start will leave a hole that shot may spill out of. Too much crimp start can
cause a “swirl” in the center of the crimp or cause a “buckle” near the top of the loaded round.
Crimp: This is an up or down adjustment. Adjust to your desired finished crimp depth. Adding spring pressure will flatten
out a concave crimp. Reducing spring pressure will flatten out a peaked crimp.
