mehavey said:The Hornady's reference point is off the shoulder, not the case base against the bolt face.
The Hornady tool uses a plastic push rod from the bottom of the bullet that is pretty flexible. I have wondered how much force it would take to make that rod flex enough to to then push the bullet out further when the rod was relaxed after the set screw is tightened.Looks like the red Loctite is all being applied inside the case neck, which would be OK. It only sets up in the absence of air, so in the rest of the chamber, it should be possible to wipe off spills. Loctite does sell a solvent for it if you have a contrary experience.
The thing that surprises me is how much longer the Hornady OAL gauge measurement is. Something is amiss. I've seen the OAL gauge measurements come up short because of a bullet wedging against the edge of the start of the feebore, but long? Unless your hands are strong enough to start a bullet into the rifling, I don't know how a too-long number could result. It makes me suspect the Loctite and jam numbers are actually short.

I have not watched this video yet, but I have managed to get a difference of about .020" doing this intentionally. Surprisingly, it does not take as much force as one might assume to flex that rod.
A sure recipe for disaster should you have a squib due to a faulty primer etc
But wouldn't it be nice to actually know what baseline you're measuring against ? [he asks ]....and I could care less if the whether the bullet is .015 or .013 or .018
as I can repeat the measurement ....
