Shotgun Jones,,do you have 231 data for 12 ga 2.5 or 2 3/4 I have quite a bit of 231 .Mark
I do not. My point is that we need it tested to see if it's suitable. It may or may not be.... it is however available at the present.
Pistol and shotgun powders certainly overlap. I recall Bullseye loads for light 12.
As far as who publishes loads, what matters is if they are actually pressure gun tested and the pressure listed.
Manufacturers (and others) have run a great variety of loads through a pressure gun that are in no way practical if you try i to actually build them.
