Who makes modified cases now?

Sadly no, he retired the shop.


Your size die can be used as a holding tool. If you have a drill press, the job is trivial and easy to run with a drill and tap. If you are used to work like this, a hand drill and vise are enough, along with the drill and tap.

Will the size die keep it from spinning when you drill and tap?

 

[Heavy Metal 1]

I made a modified case with my drill press and by hand threading. Instead of using the die as the case holder I used a piece of wood. I drilled a hole in the wood very close to the size of the brass then cut a through kerf lengthwise in the wood from one end to the hole (envision what a tuning fork looks like) so after I set the brass in the hole I clamped the "legs" closed and this held the brass securley without scratching or deforming it. That held it in place to be drilled then tapped. I took my time and it turned out prefectly.

Sorry if this has been answered many times but is someone offering homemade modified case out there?
Thanks

If your not certain you can pull it off with the 20 TAC case, send 2 fired pieces of brass to Hornady and they will take care of it. Ypu will hey both pieces returned to you. Had to do this back-when, when there was nothing available for 6x47 Lapua.

This is as simple as it gets but I do them in collets, in a lathe. Center drill, drill, then tap. The tap size is 5/16-36.

I'll ask for a lathe under the tree.

Lol! Your op was asking if someone offered this service. I answered that and after reading several posts suggesting ways to improvise, just thought I'd mention the correct way to do it. Sorry, I didn't realize you were looking for a way to do it yourself. Good luck and happy Thanksgiving.

Single point it in your lathe. That tool uses a weird thread. Dont think a tap was readily available.

Yes it is readily available.

I have used a barrel vise and tighten a piece of brass under the top crossmember on the brass head so it won’t bend the case because I don’t have a real vise. I hit it with a drill that looked about right and then ran the Amazon tap in there. If I did it, it’s not really difficult. I’ve got really limited machining knowledge. The first stuff I ever drilled and tapped has been within the last year or so.

Had issues with Hornady and "modified cases". Forgot what caliber but got the case back and the bullet wouldn't slide in the case neck. (???)
The object of the bullet sliding in the neck is so you can find the lands and adjust the OAL of your ammo accordingly!!!
Tried calling and explaining to the "Gal" what the issue was but it fell on deaf ears.
Drilling and tapping are fine till you crush a case "or two" trying to get the job done.
Got modified cases for every caliber I shoot/load for, all from Hornady till the last issue. Someone didn't know what they were doing.

Here’s what you need…

 

[AlNyhus]

I make them with a case fired in the chamber and then full length sized. After drilling and tapping in the lathe, I ream the neck to .001 over the bullet diameter for a light slip fit. If the bullet fit in the neck is too loose, you'll get wonky inconsistent readings.

Good shootin' -Al

I have a ton of modified cases from standard cartridges to wildcats. All the brass was fired in my rifles and then shipped to Hornady (un-resized). They drill and tap them, which I can't do, and return cases rather quickly.

There are guys on various forums that offer to provide the same service for free, but I've always used Hornady.

OP follow up
Well once again I tried to make my own. drilled and tapped fine but I damaged the case just enough holding it so it would not chamber. Cant size it because there is so little rim left.
Solution...Im sending some fired cases to gunsandgunsmithing. thanks in advance!
Meanwhile to get the BTO measurements I needed, I took the f pin assembly and the ejector out of the Cooper bolt and used the closing bolt method. Its probably more acurate than the Hornady (stoney point) tool anyway. Thanks to you all!
