As a 16ga shooter, I remember being really excited to hear that Federal had come out with a factory 7/8 oz 16ga load. But I wasn't thinking clearly. Federal wasn't looking at the niche market of the relatively small number of people who seek out light loads to shoot in vintage/foreign guns. They were looking at dove hunters. And those shells had a velocity of somewhere north of 1300 fps IIRC.
The Winchester low noise/low recoil shells are one way to go. But shooting skeet on days when it's well below freezing, I've heard quite a few "poofy" reports. Might work OK in more moderate climates.
Going with CIP proof ammo will reduce pressure somewhat, their average service pressure for "standard" loads being several hundred psi below our SAAMI standard. But they're still close to 11,000 psi as we measure it.
The solution has always been to reload. Except you need the right components to turn out low pressure loads. And you may very well have difficulty finding those.
