I've used SR7625 in '24gram' shot loads in 12ga with AA cases.
24gram is .85 where 7/8oz is .875,,I think I got that right.
Plenty of loads on the IMR site with CB1100 wads or Winchester brand wads and Win209 primers.
Just search for '24gram' shot weight & 7625 powder.
I've been using Cheddites and a standard 7/8 loading bar in my MEC,,but that's my decision,,and not on the chart.
Pressures run from 3500 to 5000psi with velocity at 1150 to 1325fps.
I don't think any combination of components on the charts gets a rating over 6400psi. Most in the 4000/5000psi range.
Not the clean burning propertys of Clays and some others, but it's not BP either.
Reminds me of RedDot in what's left behind in the bore from shooting.
