[QUOTE="reformedcitykid, post: 3070986, member: 127649"] Fellas, thanks for the input! To clarify, I measured CBTO using the Hornady OAL gauge, then removed the comparator from the calipers and measured COAL while still attached to the OAL gauge, so I'm not confusing the 2 numbers. Yes, I am trying to find the lands. And yes, I understand that book COAL is an estimation and every rifle is different, which is why I’m trying to find my rifles’ measurements to go off of. However it is a good basic reference number and being .3 off raised some flags. However, after fiddling with it a bit more and using a few different types of bullets, I think the issue lies with the modified case. It seems there is too much neck tension causing the bullet to meet what feels to be the lands. The bullets are not able to fall freely from the OAL if I turn it upside down. I'm going to sand/polish the inside of the neck to see if that works and will report back. Thanks! [/QUOTE]
