Larry,
It says this on the back of the BH209 bottle.
"For bullet/sabot combinations up to 300 grains, DO NOT exceed 120 volumetric units of Blackhorn 209"
"For bullet/sabot combinations over 300 grains, or conical bullets over 300 grains, check the blackhorn209.com website for approved loads"
It also says this on their website.
"LOAD DATA FOR BLACKHORN 209This information is intended to be used as a reference. Each individual must determine what is the best and safest load for their equipment. The loads described on this site were generated at the ballistics test facilities of Western Powders, Inc. in accordance with SAAMI (Shooting Arms and Ammunition Institute) guidelines. All loads were fired through test barrels and individual results fired through different firearms may vary.
Shooters are cautioned to read and follow safe loading practices as indicated by your firearm manufacturer."

The rifle manufacturers are the ones saying it is safe to shoot 3 Pellet or 150 gr loose powder charges.
From the Hodgdon website.
