I've cut down 357 Max cases to nominal 1.380", made the extractor groove with a tool ground to the spec with a 26 degree lead angle. Extractor groove depth is within .001 of .348 either way. Dummy shells eject normally. Cut one of the shells in half to see how it looks with regard to the shell meat. Also showed it to some local pros who believe it to be a sound shell for a reload.
Loading Data is really rough to find outside of 4227.
Grabbed some data using 2400 and have been seriously looking at Winchester 296 and 680.
I have both, gratis from a friend, neither is burning the nose yet. Repackaged in plastic containers from the metal ones.
Bullets are swaged: FMJ 147 grain by .351; JHP 180 grain by .351; JRN 180grain by .351
Loaded 2400 x 19; 2400 x 18; 2400 x16 for the 180 grain slugs
Loaded 2400 x 20.3; 2400 x 19.2; 2400 x17.1 for the 147 grain FMJ slugs
(used Powley for these lighter slug calculations)
Considering 296 (probably load today) 296 @19;18 and 16 grains for the 180 slugs
and 680 @ 19; 18 and 16 also. This seems a bit timid according to some of the information I've gathered.
For the 147 grain FMJ I'm thinking to use Powley again but I've read some things which stated Powley's formula was based on IMR powders only. Information provided me with the formula was otherwise. so the range for the 680 would be:
147 gr. FMJ w/680 x 20.28; 19.21 and 17.08 respectively.
The only other condition that vexes a little is the overall length of the bullets.
I have some loads from Buffalo Arms which measure way less than the 1.900" called for and found most of the dummy bullets I've loaded for length and crimp as magazine and ejector testers like to be about 1.860 to 1.870; the loaded bullets which came with the gun measure about 1.845 or less. Certainly would like some feedback on this.
