loading 9mm with refurbished range-brass using 121 gr Berry's hp hollow-base at COAL of 1.085 - 1.095 " which plunk-drops at the correct depth to chamber hood and started looking at COALs scratching my pointy little head at published COALs of 1.150 - 1.175 " (6.6 gr HS-6 not an issue.)
seems odd.... calipers zeroed - base to flat hp nose +/- 0.010 " attributed to nose variations (burs) and/or seating die taper-crimp mode reacting to different caseneck thickness of range brass.
Any observations from you would be appreciated - not worried about safety or function - just wanted to brag about my new sa-35 which must remain unfired until my B-day (groan).
