Bruce: In the words of Will Rogers "All I know is just what I read in the papers (and on the internet), and that's an alibi for my ignorance."
I'm a bit stunned regarding the .075" recommendation just past the forcing cones
My NON-EXPERT opinion: It's a lot easier to give
pressure recommendations since that information is what shell makers give, when we all know,
when using shells for which the gun was originally intended, IN UNALTERED AND INTACT barrels, the primary issue is
recoil and the effect thereof on both lock up and the 100 year old wood.
Since the mid-1890s the guns were designed to be used with Nitro Powder
Remington Model 1889 "For Nitro Powder"
And we know the old boys were using some real boomers

Charles Grimm defeats Doc Carver in Chicago for the “Cast Iron Metal”
Grimm used a 12-bore L.C. Smith gun, 7 3/4 pounds,
3 3/4 drams Schultze, 1 1/4 ounce No. 7 shot, in U.M.C. Trap shell.
Carver used a 12-bore Cashmore gun, 8 pounds weight,
4 drams of Carver powder, 1 1/4 No. 7 shot, in U.M.C. Trap shell.
However, very few of us can know what sort of abuse our vintage guns have been subjected to over the last 100 years, the wood is now 100 years old and may well be oil soaked, so prudence might suggest using a Benelli SBE for 3" 1 3/4 oz Fiocchi Golden Pheasant loads like most of the low life philistines with whom I hunt S. Dakota & Kansas pheasants
