I'm about to buy a AUSTRIAN-made Cape-gun in 16 gauge X 9.3x72R rifle with hammers, with an extra pair of 16 gauge barrels in a "luggage case".
(YES, it is NITRO-PROOFED & was "factory rebuilt"/re-proofed in OCT 1943 in Berlin, Germany.)

Do any of you have a suitable "NEAR-MAXIMUM" load for that old-school caliber that is fully-suitable for BIG game, that use JSP/GCCB, BOXER primers & COMMON in the USA powders?? - For example TRAIL BOSS, Reloder 15 or IMR 4895?? = In Europe, the old-school 9.3x72R is considered to be SUITABLE for hunting MOOSE, RED DEER, REINDEER, etc out to 200M.
(Like so many old-school calibers, 8x57mm Mauser for one such, the USA's handloading manuals is obviously "down-loaded" to Black Power ballistics = about 1450FPS.)

NOTE: The European handloading manuals, which have velocities over 2000FPS, ONLY list "NOT available in the USA" powders & Berdan primers.

The 9th editor of the Hornady manual has loads for the 9.3 x 74R. Sure you have the right case length? Hornady shows 2300 f/s with the 286 gr loads, A couple of loads at 2300 f/s with 300 gr. Just noticed I have the same velocities for both loads, not right and data book now back downstairs. Maybe 2200 with 300 gr.

If there's a shorter round, I'm guessing it was black powder and they lengthened the case to keep someone from dropping a smokeless load into a weaker gun. The oldest load manual I've got skips that bore entirely (but has loads for .451 & 401 Winchester).

William R. Moore,

YES, the 9.3x72R is a MUCH LESS powerful round than the 9.3x74mm round, which has a good reputation in Africa on Cape Buffalo, rhino, hippo, lion & even elephant.
(The 9.3x74mm is considered to be about the same power as the .375 H&H.)

The 9.3x72R is currently factory loaded by S&B to about the ballistic equivalent of the .35 Remington at about 2000FPS,with 200 grain JSP. - I'm told that the 9.3x72R "won its spurs" as an adequate woods caliber in Europe for RED DEER & WILD BOAR but that it was POORLY regarded in Africa as unsuitable for "dangerous game" .
(I'm looking for a similar handload using a 200-220 grain GCCB.)

Btw, the 9.3x72 was ONCE factory-loaded with a 250 grain GCLFP at about 1700 FPS, to be the "twin" of .35 WCF.
Note: The 9.3x62mmMauser is BETWEEN the 9.3x72 & the 9.3x74 in power.

FYI 9.3 x 74R

My old Speer manual show 53.0 grains of IMR 4898 for a 270 grain .368 dia Speer spritzer. Lists some other American powders for the same bullet. I'll post it if interested.

I found this info from a guy who loaded for a drilling:

I have some info from when I was looking at drillings. This is not first hand I just saved it. Be careful. The 9.3 is a low ppressure round about as powerfull as a 35 Rem. The 9.3x74 is much more powerfull. If interested PM me a email and I'll send more. I know they aren't for your cast bullet but might be helpful. I don't think you can go wrong with 3031.

These are from "The Accurate Rifle" magazine, issue vol6 #9, Oct. 2003.

Just a couple of notes... Don't worry about the Nitro Proof thing, unless there's something obviously wrong with the gun, most doubles or triples are just fine.

Also, many of the cape guns were built with the shotgun barrels regulated for slugs. So check a slug load on paper, you may be pleasantly surprised.
