Not scientific but using common sense. The old Hercules manuals gave some 10ga 2 7/8" 1 1/4 oz loads that called for 29 gr of Red Dot with a plastic shot cup, no specified primer. Seeing the velocity was 1360 I knew it was a hot load. I considered those facts and realized I was shooting 10% lighter shot load with 1 1/8 oz and 14% less powder at 25 grains. Shooting the gun at trap targets the loads worked great but I felt a little more recoil than I do from other known loads, nothing bad, just a little more. That caused me to lower the charge weight to 22 grains and see how they work.
Bill how many grains of Red Dot are you using and with what shot weights?
As you know we have not a great deal of "data" for the short ten and powder companies and the like don't want to give us much help when we ask.
