Had on blow up on me in 2001-2002'ish, one of the first of the $700 batch that came into Canada. I was at a friends place who let shoot a couple mags through his gun, trouble was my former buddy liked to drink and drink heavily while he reloaded. So after the smoke cleared, literally, and I stopped swearing and got the bleeding stopped (never seen a barrel fly that far) I took some rounds home to pull apart. Hmmm, all three were loaded with 45 grs of what appeared to be Unique! Yup a quick trip to my friends loading bench showed the powder dump to be half full of Unique, he had been drinking and loading for his .38 special, and forgot to dump the Unique out before topping up with the IMR-4895!
My left hand still hurts in cold weather
