I know I had a load in my standard Roberts. Not sure I made one up for my AI. It will be maybe a week before I can get around well enough to go look (getting old sucks). But I'm using IMR 4350 in most of my AI loads. A general rule of thumb is to start with standard Roberts data and work up. I usually start with a mid range Roberts load when I'm putting a new one together for my AI.
Just an FYI from shooting that bullet in my Roberts, I can tell you it is not fur friendly if he's using it on a pelt rifle.
