Hi:
Loading with Berry's 9mm 124gr HBFP Thick Plate Bullets.
Per Berry's COL Data Chart the correct COL for this type bullet is 1.060. That's what I am seating to meet their spec, but it seems rather deep and close to the SAAMI min of 1.000. Granted it's a Flat Nose, but concerned about excessive pressure using a fast powder; I am compensating by using the minimum published load for some test rounds.
Anyone else seat at that depth or lower?
Thanks !
