I tried the Hornady OAL gauge and bullet comparator this evening for the first time with my Savage 10 LE .308 rifle and a Sierra 175 gr SMK bullet.
Here's 10 independent measurements from the case head to the ogive:
3.279"
3.273"
3.268"
3.275"
3.275"
3.273"
3.272"
3.273"
3.274"
3.275"
3.274"
Average: 3.274" Standard deviation: 0.003" Range: 0.011"
Oh, yeah... guess I should be subtracting 1.000" off those measurements to remove the length of the comparator and bushing.
Maybe I should delete the first three measurements because I was still getting used to the device.
Given that I'm going to try seating the bullet about 0.020" off the lands, is this level of accuracy good enough? How accurately are other people measuring their bullets with this device?
Do you guys repeat the measurement with a few different bullets from the same box, so that you can see any variation due to inconsistent bullet dimensions?
