Jeez, just because the guy asked about HSM bear loads doesn't mean he's planning to go after bears.
I'll spare him any lectures about caliber choice or question his sanity.
Maybe he doesn't have a 10mm and wants ammo for the gun he does have.
I bought a box at Sportsman's Warehouse before I got the components together to load rounds like that.
Now I load a 180 grain WFN "Pugnose" from MBC that is similar to the HSM round but is coated.
I shot the load out of a 6 inch 686 and a 4 5/8 Blackhawk.
The HSM Bear load out of the 686 clocked 1300 fps. The Ruger was 1260 I think.
The spread was low too, only 15-20 fps. variation.
They were more accurate than the 3 or 4 factory loads I had on hand at the time, and the price in 2018 was $35 for 50.
I'll bet they sell for more than that now !
