Default Headspacing - doesn’t close on go

I rented some “go and no go gauges” from a place called reamerrentals.com. I followed some videos I saw on YouTube on doing it on Garands. I took out the op rod spring, unlatched the op rod. Both the go and no go gauges keep the bolt from closing. I tried it on my other Garand I know is in spec. Same story. I assume the gauges are the cause. Here is a picture. Can any explain this to me?

Did you disassemble the bolt?

Did you position the gauge's rim under the extractor?? Looks like "no" to me. Stripping the bolt will take care of that, but you don't really have to. Good Shooting. ...

Clean the chamber with a chamber brush. As mentioned remove the bolt parts and clean the bolt face. Bolt lug should touch receiver. I like to hear it click when dropped or pushed down. No force should be required. Checking headspace or gaging TE,and ME are two finger tasks.

Disassemble the bolt. It's really the only way to accurately test headspace.

BTW, YouTube can often get you in more trouble than it's worth. If you believe everything and every procedure you see there you'll eventually find out the hard way.

I'd be very careful with the idea of reaming the chamber based on a youtube video. try everything suggested here, and if it's stiff tight, lap the bolt face. bolts are cheaper than barrels if you screw it up...
what's the history of that rifle? it looks like it's 1/16'' out of battery

Thanks for the feedback. I’ll take the extractor out. I wasn’t a bull in a china shop with it. I’ll circle back

I keep an M14 med weight NM barrel, that I sawed in half, hanging in my shop as a reminder because I got in a rush with one rifle and didn't strip the bolt. I was barreling 6 that day and just missed stripping one bolt. Luckily I had a bunch of extra barrels.
