I don't have a bolt in it yet, but my goto is Leverevolution in the ARC. I also stumbled on to a really good load of 27ish grains of IMR3031 AND 75 G Vmax
My personal Howa mini starts showing pressure signs at about a half grain over the Hornady gas gun maximum so proceed with caution if you use bolt gun data. Also, I only use Hodgdon extreme powders or IMR 8208-XBR. Be careful with temperature sensitive powders like Lever and CFE.
