I've urged folks to familiarize themselves with the proof and service loads table in TPS and to follow the shot loads for the gauge provided by Parker and reproduced in TPS, and as just restated by Austin. If a person keeps the shot charge down to what Parker recommended for the gauge and pushes that charge at moderate velocities, say 1050 to 1200fps, then most all the time, they will be below the service limits. And as has been noted by Dave Noreen, dram equivalents correlate to speed.
Some of the most extreme examples of low pressure police we have had here have been when they have told people who have heavy duck 2 frame 8lb 12's with .040-.050" wall thickness that they must shoot low pressure loads. That said, I'm not a fan of these 1 1/4oz or even more 12ga loads pushed at 1300-1450 fps that the manufacturers are making and touting as premium ( and costly) pheasant loads.
And Mike, I remember when I was a kid throwing a shotshell in the fire and running the other direction. Common sense prevailed and the expected result occurred.
