Is anyone making OAL modified cases?

[GrayMcBride]

Hi there!

Looking for some assistance.

I am a reloader and I use the Hornady lock n load OAL gauge. I would like to thread one of my fired cases for use in the gauge. Has anyone done this before? I've read some DIY posts on this before but I don't have a lathe or a drill press.

If there's anyone that has the equipment and has done this before could I possibly mail you a few cases? I will pay what is fair for the service or pay with brass if you're interested. Any help would be appreciated.

Thanks!

If you have many different cartridges, it's often easier to use a metal drill rod, and a collar designed to slide over the rod. Measure from the muzzle to bolt face, then the difference to a bullet in the lands.

A friend of mine bought a reverse tap and was using fired cases but that is more time consuming then doing it from the muzzlefrom what I can tell

Look for a local machine shop or gunsmith.

I had ATRS do several for me. Wildcats that Hornady doesn't offer. Take in a fired but NOT sized casing and they do the rest.

This is easy and free.

I have the drill and the tap to do this. Bought them because some wildcats are unique.
If you are desperate, I would be happy to do a case for you. I would want 2 cases
fired in your rifle, and NOT resized. Dave.

Yea, I have the tap for it... Send me a PM. No payment needed, just cover the shipping...

To fit the Hornady OAL gauge, what is the tap size...metric?

I've made them for myself, the tap size is 5/16-36 IIRC. When I do it, I take the decapping rod assembly out of a full length die, lube the case and run it into the die. I then pop the shellholder out of the Rockchucker and remove the die from the press. This gives 360 degree grip on the tapered case without scoring it, and I can chuck it into the lathe and it will run true. Drill and tap, then put the die back in the press and slide the shellholder back into the ram and pull the case out. You then need to used an expander to open up the neck slightly over a bullet diameter so the bullet slides in and out freely. I wouldn't recommend using a fired case as the case most likely won't fit into the chamber properly and give you a proper reading. Ideally you are using a die that you tweaked to a .002" or so bump so it inserts and headspaces correctly, instead of getting stopped by the taper of the case.
