Are there any factory 1-oz. loads in 12 gauge loaded here that have pressures less than 10,000 psi?
Yes, I'm well aware of RSTs...and so I'm really asking about low-pressure loads available from Rio, Remington, Federal, Winchester and any of the other larger commercial cartridge makers.
Same question asked another way:
For owners of British 12-bore guns with 2 3/4-inch chambers and 3 1/4-ton proofs, are there low-pressure loads currently manufactured in the U.S.? (As many already know, the 3 1/4-ton proof equates to 10,000 psi or a little less.)
Any guidance appreciated.

The Winchester “Low Noise and Recoil” rounds run less than 10,000.
8400, if memory serves.

Rios are European CIP proof marked shells. Check their web page for service pressure data. Not all will be sub 10,000 psi.
If buying American made, RSTs and Polywads are your best bets for lower pressure loads. But check the manufacturer’s data for the shells you are buying. These two companies make Saami pressure loads as well.
Many Herter’s shells are also CIP marked. Again, check the manufacturer’s data for details on the loads you are looking at before purchase.
Reloading is your best option. 12 ga handloads are easy to keep under 10000 psi with readily available reloading components.

Lots of 7/8oz loads from Kent and Fiocchi. I think NobelSport and Clever Mirage are available in 1oz low pressure loads, but my sources have dried up. Need to find some.
Years ago (2005ish?) there was a lot of chatter on various boards about Winchester Super-X (silver box) shells from Italy and Australia. Word was that they were fairly low pressure and soft shooting, and a good choice for older doubles. I have not seen any published data, but I bought an awful lot of those shells and they seem to live up to the rumors. Shot them in an 1880s Brit laminated steel hammer gun with good results.

If you try the B & P Comp Ones you'd better have loads of extra firing pin protrusion, or they will misfire. I've got lots of guns, vintage and modern, they will not shoot reliably in. Smaller diameter heads than most other shells.

Best, Ted There is the AA Light and the AA Low Noise/Recoil. I can't find where I got the idea but I thought the Low Noise was significantly less than 8400 and the 8400 sounds more like what the "Light" was. I have a couple flats of the Low Noise and can barely hear or feel them. (Exaggerating only slightly). Kent has a new load (Excel?) that's down in the 7000 psi range.

Gamebore pure gold are low pressure and work well especially in the 28gram load.

If the gun is in proof you can use any CIP cartridge of the correct length.
Recently purchased boxes of Herter and Rio 2 3/4" cartridges I have are CIP. Check the boxes of other imported ammunition and if the say "CIP M" you can use them.
My wife hates the 1 ounce 16 gauge Rio's @ 1300 fps because they kick like the proverbial mule - she much prefers the Remington 1 ounce @ 1200 fps and the Herter's 1 ounce @ 1165. I'd stay away from the Rio's because of recoil but if your gun is in proof and good condition they will be safe pressure wise.
