Does anyone know what thread the Hornady OAL Gauge and Modified Cases use? I’m wanting to make a 284 modified case but finding the thread and a tap is proving difficult.

Make Your Own Modified Case for Hornady O.A.L. Gauge « Daily Bulletin
"After drilling the hole comes the tricky part — you need to tap the case with the precise 5/16″ x 36 threads per inch (tpi) right-hand thread that matches the male thread on the O.A.L. Gauge. This 5/16″ x 36 tpi tap is pretty uncommon, but you can order it from Amazon.com if you can’t source it locally."
I would also try aliexpress, US$4.60 with free shipping. Have used them a few times, usually takes 1-2 weeks. PM me if you don't know how/can't be fucked setting up an account and I will get it for you on my account

you can also get them from Tradetools.
@stagstalker I have a friend that has one, send me a couple of cases fired in your rifle and I will get them threaded up. If you put them in aself adressed envelope (prepaid ) that would be good.
Yep I've got a tap, as well, forget what brass I was fiddling with, when I had to made up a modified case 6x45 or .17 fireball perhaps.
Pmd you mate. Will get them in the post tomorrow, legend.Quote:
