Have any of you seen old published .357 Magnum reloading data for large quantities of Blue Dot with a 180 grain bullet?

5 or more years ago, a member of the Canadian forum gave me 50 rounds of 357 he didn't need The label on the box says 357 180 14BD. The only "BD" powder I can think of is Blue Dot. I looked up reloading info for Blu Dot and I didn't see any14gr loads for 357 magnum.

I broke one round down and weighed the powder and bullet.

Powder: 14.7 gr
Bullet: 186.4 gr

The case is almost full. Looks like it would be a slightly compressed load.

Reloads of unknown origin = discard.

It’s not worth worrying about their details.

Yep...Components excluding powder will canibalized and reused.

Just curious if anyone has seen data for a "BD" powder for 357 like this with a heavy bullet. Blue Dot does list 11.5 and 16 gr loads but with much lighter bullets.
