12 gauge 3" shell introduction.

[Researcher]

It is rather "strange" that the ad from Winchester, gives the loads with DuPont Smokeless, New E.C. Improved and New Schultze in grains. They were all bulk smokeless powders and should have been given in drams. Fanning's load with Infallible, a dense smokeless powder, was correctly given in grains. It was actually a rather light load, as the loading companies offered up to 28-grains of Infallible pushing 1 1/4 ounces of shot from 2 3/4 inch and longer 12-gauge hulls.

This is the best conversion I've come up with, but may not be exact

..............'E.C.'......DuPont…....Schultz…..... ..Ballistite....Infallible

3 dram....42...........36.5............42........... ...24.............21 grains
3 1/4…...45.5.........41...............45............. .26.............23
3 1/2…...49............43...............48............ ..28.............25
