Left to Right:
Factory 7.62x39 "Soviet", .311" 123 grain steel core FMJ (Barnaul) -- approx. 2300-2400 fps
***
7.5x33R handload (2.9 grains IMR Trail Boss, .314" H&N 100 grain LWC, full length 32-20 WCF Winchester brass resized in a 30 Carbine die, bullet seated with a 30 Luger die, brass rim thinned/filed) -- approx. 791-816 fps
***
7.5x33R handload (3.1 grains IMR Trail Boss, deep seated .314" H&N 100 grain LWC, full length 32-20 WCF Starline brass resized in a 30 Carbine die, bullet seated with a 30 Luger die) -- approx. 841-866 fps (max load)
Note: this is once-fired brass. All remnants of the 32-20 WCP shoulder are gone. Starline brass 32-20 rims fit without modification. This is my 'go-to' target load. It's no wimp either.

Factory 7.5mm Swiss Ordnance (10.2 grains of Swiss black powder, .319" 108 grain FMJ, thin waxed cardboard wad, Berdan primed) -- approx. 720 fps
1958 headstamp

7.5x23R handload (2.6 grains IMR Trail Boss, homemade .312" 98 grain LRNFP, cut to Swiss Ordnance spec 32-20 WCF Remington brass resized in a 7.5 Swedish Nagant die, bullet seated with a 32 S&W Long die) -- approx. 716-741 fps
***
7.5x23R handload (3.1 grains IMR Trail Boss, .311" Hornady 71 grain 32 ACP FMJ, cut to Swiss Ordnance spec 32-20 WCF Remington brass resized in a 7.5 Swedish Nagant die, bullet seated with a 30 Luger die) -- approx. 950-975 fps (max load, but not intended for the earlier "thin strap" variants... prior to serial 4301)
This is my "barrel cleaning" round. I usually end the shooting day with 6 of these screamers to get the lead out.
***
32 S&W Long handload (3.1 grains IMR Trail Boss, .311" Hornady 71 grain 32 ACP FMJ, Remington 32 S&W Long brass resized in a 30 Carbine die, bullet seated with a 30 Luger die) -- approx. 950-975 fps (max load, and not intended for top break 32 S&W revolvers!)
The rim diameter is just wide enough to fit without falling into the chamber. While not ideal, 32 S&W Long will fire, but most cases will exhibit bulging to varying degrees, and the occasional split. I DO NOT endorse firing this cartridge from a M1882 Swiss Ordnance revolver.

Factory standard velocity Winchester 40 grain 22LR
Note: All handloads use either CCI or Winchester small pistol primers, utilize a light roll crimp, are rated under 1000 fps, and provide excellent accuracy. HOWEVER, USE AT YOUR OWN RISK !
