So good news/bad news! The bad news is that i may have to do more machining. The good news is that the thing works, all i did tonight was add a thin film of oil to the sheet and it formed a cup, i did not even increase the radius or buff the cone yet! So...its getting there. Problem is that cups walls are way to high and uneven. Is it stretching? I think so. Am i off in my calculations of the disk diameter? Is .180 id + 2(.119) not .418? The copper punctured disk is without the oil the brass cup is with the oil, they are next to a used commercial primer.

I will obviously work on the radius and buff it to a mirror finish before thinking about more machining, but its encouraging.
So for the fun of it, i quickly trimmed down the cup to the approximate height and loaded it, the anvil fits nicely. I then primed a 45 case and the fit felt EXACTLY like a new primer, smooth, even and snug. It fired perfectly. View attachment 836084 View attachment 836085 View attachment 836086
hey that's pretty nice! You can certainly make quick trims with that! What do you think aweshoot? Do you prefer the idea of using spent 22.lr casings or stamping from brass sheets? There is a give and a take for both.
i will have to test the .22lr material before going any further though. it cant show signs of failure like the other stuff. I got into designing a whole new die that would both form and trim in one stroke but there is no use in going further with it if the material is incapable of handling pressure.
I built a 6 inch long slide 1911 to shoot the 460. Its one of my favorite calibers, it recoils like a mid range 357 but puts out about 1100 ftlbs with the load i used. I just loaded a 500 magnum with 41 grains of enforcer under a 300 grain pill and one of the test primers, will try it out tomorrow.
This is the 460, the 460 is basically a 45 acp magnum.

I only have one strikerfire, it a 9mm. You have a point there...when i get to making spp ill test it.
I dont think i can wait to make the dies, the other stuff will have to wait...
