hornady headspace gauge?

I like mine. With every new cartridge I'm buying some new bushing for the darned thing, and a "modified case". But it works as advertised.

I've had it since it was the Stoney Point Comparator, pre Hornady.

Anyone use the hornady headspace gauges?

I had issues with 223rem getting stuck in the rifling and one thing that was brought up while talking to people was I could be moving the should back too much and letting the case go deeper.

I want to make sure im doing everything right so was wondering about this tool.

what you say?

Expound upon "getting stuck in the rifling". Are you chambering a round and the bullet is being pulled out when you extract the unfired round?

You may be pushing the shoulder back too far, but that doesn't have anything to do with a round being long enough for the bullet to engage the rifling.

I use the Hornady headspace gauge and the modified case/OAL/bullet comparator thingy also. They're two different but closely related tools. If you're having issues with overall-length and the bullet hitting the rifling, you need the OAL tool and a 223 modified case. If you think you're pushing the shoulder back too far, then you need the headspace gauge. The Headspace gauge doesn't use a modified case or the slidey bullet pusher-outer thingy. (That's the official name, I think. ) It just goes off the base of the cartridge to the datum line on the shoulder of the case.

Have to agree, it works. If you measure a case before and after sizing it will indicate the difference.

I use it with religious dedication

Yes, I use Hornady "headspace gauges", which are actually headspace comparators. I use them with Forster headspace go gauges to compare with headspace dimensions of sized brass and adjust sizing dies accordingly.

All of the forums are filled with one post after another from people who don't know how to adjust their sizing dies. This tool when used properly is what allows you to do exactly that.
You can also use part of it along with a caliber specific bullet comparator insert to find the ogive to base OAL that works for your rifle and then using it to set your bullet seating depth no matter what bullet you're using.
