Looks like 7.62x39 would work as well as anything.
Handloader's Manual of Cartridge Conversions says 9.3x72R is a good one to make them from, but I would try x39 first.
I make .401 brass from 7.62x39 and it is the way to go. Shooting in a Win. 11910SL the cases bind slightly just above the rim. Only an issue if trying to eject a cartridge that has not been fired. I chuck the cases by the neck in a drill press and use a file to thin the lower head portion of the brass. After this they function fine. Best thing is 7.62x39 cases are cheap and easy to come by.
On page 311 of Donnelly's Handloaders Manual of Cartridge Conversions, it gives this info.
Make from: 9.3x72R. Turn rim to .457" dia. and back
chamfer. Cut case to 1.55" and taper expand to .410" dia.
Trim to length and size in .401 die With exapander removed.
I.D. neck ream. Chamfer and F/L size. Fireform in chamber.
I wonder why he didn't suggest 7.62x39? I'd think it would have been plenty common even back then.
I cut 414 Super Mag brass to length (1.495"). I do not cut an extractor groove.
Reduce the head diameter (.460") with a drill press and file
I use Accurate Mold #41-208L (206 gr bullets) .408” diameter
Or Western Bullets 250-gr. lead plain base #410426
IMR 4227: 22 grs minimum
UNIQUE – 10, 11, & 12 grs all worked. 12 grs felt like IMR4227.
Most of the cartridge conversion books were written in the 1960's or before. The 7.62x39 didn't become widely accessible in the U.S. until the late 1980'ss IIRC.Originally Posted by Bazoo
I do remember reading Bob Milek stating that he and Steve Herrett would never have made the .30 Herrett if the 7.62x39 was readily available at the time.
It is also why you get recommendations to use such weird to us now cartridges like the .30 Remington as a parent case. These days people that have working .30 Remington rifles are converting .30-30 brass to feed their guns.
