I recently purchases a Hornady OAL Gauge and the appropriate modified cases to determine my COAL to touch the lands. I have previously used the old "use the rifle to seat a bullet" method. The problem I am having is this: using my new OAL gauge, my COAL's are coming in much shorter (.120") than my old method. Could I possibly be feeling the lead while I am using the Hornady OAL Gauge? I use a cleaning rod through the muzzle to push the bullet back and forth a few times, and consistantly hit a "wall" on the forward stroke. The rifles are clean with a fresh patch of hoppes weatherguard oil ran through them. Am I not pushing hard enough with my Hornady OAL Gauge?
