While shooting sporting clays yesterday I ran out of RSTs shells for my 1882 WC Scott hammer gun. I was on the 2nd to last station so I grabbed some low recoil 1oz Herters to finish the round. To my surprise, the Herters kicked way less than the RSTs (quieter too). They also run run about 1/2 the price. So I'm thinking about using them regularly but was wondering about the PSI on these shells... The 1oz, low-recoil, 1060 fps shells. After shooting them, I would guess them to be very low. But how suitable are they for vintage guns? The gun I was shooting is a pretty stout piece. .044 thickness on 30" damascus barrels, 7 1/2 lbs, dolls head ext, etc. Chambers appear to have been opened to 2 3/4". The gun is perfect for sporting clays. Any opinions and insight would be much appreciated. Adam

I wouldn't use them in that gun, Adam, 9K is pretty high for damascus, IMO.

Adam's took a walk on the wild side...from what I can see she's a nice looking old girl. A lifted Gunsinternational photo Dreaded Damascus barrels with lengthened chambers without a reproof (with most likely a good honing er two) and 9000 psi shells ?

Wow... 9000 psi???? I sure didn't expect that from a shell that kicked so little! Oh well. What is a safe PSI to keep under for Damascus barrel? 6k?

So with a measured .044" wall thickness you guys are worried at 9K? I would not be. What is CIP for a Brit 2&1/2" shell? Very close to 9K. You have very thick walls if measured correctly.....proceed and have fun.

Herter's offers a 1 oz. Field & Target @ 1290 fps, a Select Field Dove & Quail 1 oz. at 1250 fps, and the Target LR 1 oz. @ 1060 fps. B&P Competition One 1 oz. at 1160 fps is 6530 psi. I suspect the 9000 psi is the Field & Target.
If the chambers have been lengthened, the wall thickness at the end of the chamber and forcing cone is critical.

I'm with Steve on this one. Nine thou is a bit high, but not egregiously so. If those tubes are indeed 44-thousandths then those shells will never come close to causing this gun a problem (barring a stuck wad, but that's any gun). Moreover, if felt recoil isn't bad then I'd not be too-concerned about the head of the stock either.

"IF" a shell loaded with 1oz of shot to 1060 FPS does indeed hit 9K psi it's going to hit it very quickly in the chamber & then fall off rapidly. I assume the .044" thickness is down the barrel. Pressure is going to be way down by that point. What is important here is the wall thickness over the chamber & particularly where it joins the forcing cone. With the gun weighing in at 7˝ lbs I'm betting it's not particularly thin here either. Assuming adequate wall thickness here in the chamber area I would not be at all concerned over a pressure of 9K with that light a load. In fact with that load I don't think I would be overly concerned as to what the actual pressure even is.

I would not shoot cheap shells in nice vintage European gun like that. I would not, however, have any problems putting them through: Parker Bros, Fox,.... Lefever or L.C. Smith with fluid steel barrels. All A.H. Fox guns had fluid steel barrels them rest you have to be careful with.
