HalfaDouble,
Check again In the 360-2 1/4 and 9.3/360s group, the s indicates plural meaning all the 9.3s based on the 360 case, including 9.3X72R E, D, and Normalizert, as well as a raft of others. The 9.3X72( S&S) is often confused in writing with the 9.3X 72R Noralizert(standardized), but in use it is sometimes confused with the 9.3x74R. I have one that I bought as a 9.3X74 that as usual for the time was not clearly marked as to the cartridge it used. I had a scope mounted in claw mounts and it was sighted in as 9.3x74R. After killing several Red Deer with it, it blew a primer. I had a gas tight firing pin installed by another German gunsmith and shot more Red Deer with it. After moving back home, I started loading for a 9.3x57 and having some of the 9.3X74R cases I had shot in the Sauer BF, I just checked to see if a 9.3 250 grain bullet would enter the case. I was surprised that it wouldn't enter. After having the scope mounted, I had discovered that it wouldn't group with any bullet longer than the factory round nose jacketed bullet and I wanted to see if the 250 grain spitzer would work. Remembering the 9.3X72R was loaded with a lighter 185 grain bullet, it dawned on me after all those years that the rifle was chambered for the Sauer and Son round. After close examination of the case fired in the rifle, I discovered that where the case-mouth was crimped into the bullet the case diameter was small enough to go past the chamber into the throat. upon firing it wouldn't expand enough, thereby raising the gas pressure enough to blow the primer. Now I just shorten the cases by 2mm and load the 250 grain bullets in my 9.3x74R dies, it works like a charm. I form 6.5x58R S&S from original length 38-55 cases to avoid shortening 9.3X72R that much. A friend gave me some 9.3s already sized and I may break down and try them. The Brits might not have used cordite when the foil cases were used.

No problem, as you can see from above, we all sometimes write things that are confusing. I still think your Watson is a very nice rifle.
