I have a set of .30 Herrett dies you’re welcome to have if you continue with that chambering.
The box is marked Thompson Center but are actually Pacific Durachrome. Lord knows I’ll never use them! PM your addy and I’ll mail out if you want them.

PS I’ve got .357 Herrett too… same deal if anyone needs them.

There are many ways to do that, broaching, filing in using "file fixtures" similar to methods used in the 1800's by gun makers*, casting and wire cutting/EDM.
This projects receiver started life as a Rodney casting then I have modified it. Also to insure the mortise was true I did take a skim cut using a Wire EDM. So you can see many ways to skin the kitty. On the floor plate which has a much more complicated mortised thru slot I have milled and filed it to shape and will also use broaching to complete the final work required on it.

* a task generally reserved for the apprentices as it was hard physical work.


Thats what I was afraid you would say. I attempted several different ways, Filling, using a corner broach in the mill, yelling at it, cussing at it, etc... I eventually got smart and figured out CAD enough no make a print and sent it out to one of the online machining companies. I was able to get 4 made at a very reasonable price. Mind you these where just the mortise cut into a block of 4140 and not other work done to the block.

That project was coming along nicely until i got side tracked on new projects.

Time for an update and the news isn’t good. In fact, I am putting this project on an indefinite hold due to a discovered issue with the receiver casting. As stated earlier it began life as a casting of an 1897 WR. I informed Rodney of the issue and he quickly moved to replace it. However, when the new casting was delivered, I discovered a dimensional difference between the original casting and the newly received casting that makes the new one unusable for this project. The as cast breech block mortise is wider than the breech blocks and that is before the casting is cleaned up and smoothed, which would only make the difference worst. A very unacceptable fit. The new casting would not even work with the “original casting kits” of parts, so Rodney has replaced them as well. I want to say Rodney has been a real stand-up fellow concerning this issue.

So, to continue with the project plan, using the new receiver casting, I would need to scrap the breech block and the floor plate I have made. A lot of work for naught. (Not even mentioning all the work I did on the receiver.) The other alternative is to table the use of the casting and the “casting kit” parts and make the receiver part out of bar stock from scratch. That would be a fairly significant leap but not impossible. Time and noodling on the subject will determine the path forward...

After watching your work for awhile, I have come to the conclusion that very few things are impossible for you.
