I tried some 7828 in mine and it loved it. It also shoots several other powders ok.
Speer data would indicate you're leaving a few hundred fps on the table with that one.
Did you clock it?

I wonder why the low velocity with 7828??? Most pf the data I've seen for other cartridge show it close to RL-22. In fact, when I was looking for RL-22 for my .280, none was on the shelf at the LGS. Checking in a couple of manuals showed velocity to be very close to RL-22 so I used that. My .280 didn't like it. I got the speed but no accuracy. Strange that Speer has it so low over the velocity lever. I wonder why????
