Just don't care for pellets.
I've found that all three of my rifle's that shoot the PB's like 90grns. loose powder or 75grns. Triple Seven. My choice of hunting load is the 250grn. PB bullet with 90grns. American Pioneer Powder(APP). APP burns fairly clean.
I've not tried the Blackhorn 209 powder but have read nothing but positive things about it(except it's price
)... and understand it requires a hotter primer compared to some of the other powders.
