[QUOTE="Greyfox, post: 1260290, member: 10291"] Question; when you measure the case/bullet after taking a seating depth with the guage are you measuring to the tip of the bullet, or to the bullets ogive using a comparator? Bullets can have variation in OAL(as much as .010") but the base of the bullet to ogive is generally very consistent. This is particularly the case with match style hollow tip bullets from Berger, Sierra, and JLK. Also, the important measurement is from the bolt face(bottom of the case) to the bullets ogive. It's important that the test case be in contact with the bolt face when the action is closed and a measurement is taken. Too much headspace will also give erroneous readings. IMO. [/QUOTE]
