I used Unique in 38 Specials and 45 ACP’s when I shot indoor pistol league. I found Unique to be a good powder that produced accurate loads. I’m still using powder from a keg I bought quite a while ago. Since the indoor ranges at the high school armories have been shut down, there’s not much indoor shooting as there once was.
I haven’t used Unique in any hunting loads that I recall other than cotton tails and squirrels.
