HSM has been assembling ammunition since 1968. Today they produce six brands of ammunition Hunting, Cowboy Action, Bear Load, Varmint, Pro Pistol and Self Defense. Today I will be cold weather testing Bear Load and Pro Pistol loads. I will shoot 6 rounds of this ammunition across the chronograph from two pistols Ruger Blackhawk 10mm and SR1911 10MM. The chronograph will be setup 3 yards down range. To test for accuracy these loads will be fired from a bench pistol rest at 25 yards.
I fired 6 rounds through the SR1911 and Ruger Blackhawk in 27 degree weather to find out how sensitive this ammunition is to cold weather. Part 2 will consist of firing the same loads with the same pistols in weather above 60 degree's. Stay Tuned for Part 2:

The advertised velocity of the Bear Loads were pretty much the same as the results I achieved today. Which could lead one to believe that the cold had no effect at all on this ammunition, though I still plan to test these loads in warmer weather conditions.
