It is the voluntary stamp on the sides of the tube. Captain Edward Schultze devised the powder: http://books.google.com/books?id=scFMAAA...der&f=falseService load would be the typical/average central-fire cartridge loading.  Kind Regards, Raimey rse

Raimey,
I believe the paragraph you posted applied to nitro proof for rifle barrels, not shotgun.Since the gun was proofed pre 1912, it would have gone by the old rules, regarding whether the proof load or duty load was shown for the shot tubes.Are you comming to B'ham next weekend?
Barkey, you should be able to shoot the drilling with appropriate loads.You seem to have a "leg up" on loading for it because you have some brass.From the age your ammo boxes seem to be, I suspect the brass is berdan primed.It can still be hand loaded, you just must use different process for depriming and use different primers.To be sure, shine a light into the case;if boxer primed, there will be a central flash hole, if berdan primed, there will likely be two offset flash holes.
Mike

Der Ami,
The load information was stamped on the side of both shotgun barrels.
What is the difference between Proof load and Duty load?

You are correct Ford, but I have not seen another reference for the 1893 addition for semi-smokeless proof for the scattergun voluntary proof. Not sure the pressure would approach 4k atm but the stamp type is the same. Proof load can be 2 or 3 times the service load. So 2 times service/duty load = proof load depending on pass but the multiplier is not linear across the load. Say the powder charge will be tripled while the shot load will be double, etc.
Ford, thanks for reminding me on the event. Um, are you going to make the effort?
Kind Regards,
Raimey

Again Ford, you are correct as I grabbed the wrong paragraph:  Flintenläuf - Reichsgesetzblatt v. 23. Juli 1893  Troisdorfer Flintenpulver by the Frankfurt on the Oder proof facility Kind Regards, Raimey rse

The gun is tight on face with some shallow pitting in the bores 2-3" from the chambers. So, I am assuming I can shoot it using 2-1/2 "low pressure" shells.
Any idea how old the rifle cartridges might be?

Raimey,
I think we will on Sat. I'm still getting over my operation and might have to come with my walker but hope to be able to just use a walking stick.

BarkeyVA,
Depending on the condition of your drilling, you should be able to use the 2 1/2"low pressure shells.The 9.3X72 was made in different versions and came fron the earlier British 360 drawn case.It is very hard to say precisely when the 9.3X72R was "born", but the earliest German use of the 360 case seems to be about 1878, with the 72mm case length showing up around 1892.
