Question using the Hornady OAL gauge

Re: Question using the Hornady OAL gauge
Chamber and bore are clean.
Using the OAL tool with the modified .308 case and a 178g amax. Pushing the bullet by the plastic rod with my finger, expecting that the bullet will stop against the lans. Is it possible that the bullet could stop in the free bore never touching the lans?
Thanks for your input, Rob

I don't see how that is possible. I have been using my OAL gauge for almost 3 years now, never saw that.

Are you asking if the bullet can move completely out of the casemouth before touching the lands, yes. But it would have to be a short bullet and a long throat.
If that's <span style="font-style: italic">not</span> what you're asking, I don't know what you'd have in there to "stop" it.....

Re: Question using the Hornady OAL gauge
Using mine, occasionally the bullet does want to stick a little, and this results in a grossly under length case. I saw another post on here about picking up a $1 36 inch 1/4 inch diameter wooden dowel at the local hardware store. This is inserted into the front of the barrel and the Oal gauge from the rear. (Minds outta tha gutter). You then "balance" the bullet between them, playing with it until you get the feel of the bullet just barely touching the lands. That being said, my 175 SMKs have triple the deviation from average length as the 178 Amax, so I measure 10 and average them, then use the average to deter ing COAL and seating depth. Works pretty well from my limited experience.

Re: Question using the Hornady OAL gauge
You might want to consider adding the bullet comparator, and measuring to the ogive instead of taking an "average" of ten and using OAL to seat the bullet. Since I started using the comparator, I never load to OAL...
