Finally, Jeff, there is a 7400 psi 2 1/2” load using your Green Dot in the spreadsheet right here (3/4 oz lead, 15.5 gr, Ched 209, PB SG-16 wad, 1177 fps). The source is noted as “fn16ga”. I’d want to know who did the pressure testing before I used it. Conventional wisdom is that Tom Armbrust and Precision Reloading’s testing and loads are far more dependable than BP’s, though some argue with that. If I couldn’t ascertain the lab that did the testing, I’d send in rounds to Tom or PR myself. It’s cheap insurance for guns you cherish.
