Can't be certain, tut, but I'm thinking that's not a 1200 bar gun given that date, and especially if there's no indication it was made specifically for the US market. There's the US importer's stamp, but that could well be as a used gun rather than as new. In fact, if there's no importer's name on the outside of the barrels, I'd say that tips the odds farther in the direction of having been brought in used.

I'd say with no markings on the barrel, that your most likely right. Wonder if one could contact the importer and if they might have any old records on it? Probably not, but I might give them a buzz just out of curiosity. One thing is for sure. It's got some damn tight chokes. PS. I'm assuming this gun would be fine for modern normal non-moose loads.

With the 1950's date and a single proof, I'd say with CIP pressures or, better yet, low pressure handloads. I'd not shoot SAAMI loads until sure of the proof.

The superior proof, instituted in 1962, was 17,600 psi. Could be that the Italian proofhouse rules have changed since 1972, but if Tut's gun was made earlier than that--and there should be a Roman numeral date code--then I'd say the lower figure applies.


Ok. Now even I'm confused. It does indeed have the following proofs.

The star with PSF under it. The star with FINITO under it and the star with the shield under it.

Wouldn't the PSF with the star provide a standard proof of PSA 12,000 and make this suitable for standard loads? BTW, it has German barrels Boehler, if that matters and tons of wall thickness.

star PSF Smokeless proof at 12,000 psi
star FINITO final proof of a gun in the completed state
star Shield mark of the Gardone Val Trompia Proof house.

The origin or composition of the barrels has nothing to do with proof pressure.

Tut, SAAMI service pressure for 12ga loads is 11,500 psi. Assuming we're correct that your gun was proofed at 12,000 psi, that's scarcely higher than the service pressure ceiling for American loads. I would not shoot standard American factory loads in that gun.

I'd stick to CIP rated ammo.

tut, the CIP service pressure is in the 8000 - 9000 psi range for the 12,000 psi proof firing.

Blowing the barrels is one of the less likely issues with high pressure. The more likely issues have to do with overstressing the action bar, the jointing, the locking, and/or the wood bedding. Pounding a gun prematurely off-face is the most likely issue.

I was thinking this particular gun would be interesting for turkey or waterfowling as its a hammer gun. However, both of those games lend themselves to more powerful loads then 8,000 - 9,000 PSI as a rule. I did some checking and loading my own can get some loads in the right pressure range, but loading up niceshot is expensive and factory loads in lower pressure non tox loads is ungodly expensive. On top of that this gun has a bit of fixing required to make it right and there's no point in spending additional money on something I have to baby anyway. All my questions were being put out there in an attempt to get smarter. Seems like I am and that's why this particular forum is a good place to get the right answers.
