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.
