I have a few flats of Federal Gold Metals that are pretty recent, that have the CIP emblem on the bottom of the box, with an enigmatic “M” next to it. But, last years Gold Metals, and some recent Top Guns do not have the emblem. Seems a bit hit or miss, to me. I wouldn’t actually be in a hurry to run the 2 3/4” Federal paper loads in a 2 1/2” English gun, either. A poke here and there at a grouse or pheasant, maybe, but, not 100 rounds on a Sunday afternoon at the club.
I like really light loads in light guns, same reason as you.
Best,
Ted
