John, I'm sure a number in this group would be willing to share low pressure "secret recipes" that have actually been sent to testing labs, myself included. Your biggest problem is that components is a whack-a-mole deal right now. Stuff appears and disappears in hours. With shotshells a seemingly minor substitution can make big differences in pressure, especially wads, so caution advised! My best advice is to start with published or borrowed loads you can find components for, back off the powder to the 1150 to 1200 FPS range, and spend some time and $$ having them tested. Tune to your needs. This is a bit time consuming but time and money well spent.
Some of my Bismuth duck loads that have been tested. I substitute lead and bismuth in loads, cannot tell the difference in pressure. I shoot these in fluid steel barrels NOT Damascus (AGAIN, REDUCED POWDER TYPICALLY REDUCES VELOCITY AND PRESSURE). MODIFY AND USE AT YOUR OWN RISK!
