I don't have any info on the RL-33 powder I use Retumbo in mine. You will probably not get the same speeds with the AB as you do with another bullet, this is do to the difference in the barrining surface on each bullet. Possibly some other factors as well. I get slower speeds with the matchkings than I do with the Bergers.
