The threads on the r type dies are 7/8-14 and will fit a standard press. But they are expencive 380.00

Yes thay are VERY.! and Darth Dave Corbin is the only one still making them.

So there a good deal if you don't mind waiting 6 months atleast to get your reloading press swage set from him

For the same price you can buy a WallNut hill's Old style- 200.00 Richard corbin's tooling>>
Die's to crunch a .22 emptly into a bullet jacket to fit into the wallnut hill 60.00

And a 3 die set to form the bullet's 350.00
--------
somtime's richard has supply in stock sales and the price of the die's drop down to about 200.00
richard can have the die set and the jacklet maker and the press to your door in about 3 month's.

Both Corbin's do a very good job although only one of them make's the die's and tooling the other one has other people
make the tooling and die's
