A handloader blew one up last Friday at the range I frequent.
I had just left and my LEO friend showed up. It appears the handloader had double charged/overcharged one round and it blew the gun up like a hand grenade.
My bud got hit by a piece of shrapnel and the owner got bloody fingers and the guy on his right got peppered in the face.
The majority of the force was directed downward.
The barrel was not bulged so it does not look like a round failed to clear the muzzle.
The case was separated at the base but the primer did not appear flattened.
It is possibly bad brass but in any event a $1400 handgun was turned into small pieces.
Fortunately, the RO's turned to and bandaged up two people and cleaned the mess up.
This is not meant to rain on your parade, but if ammunition for this particular gun is really expensive and you decide to handload, you really need to be careful.
I was over at my friend's house last night to celebrate his birthday and he showed me the piece that hit him. It was less than .5X.75 inch.
It was NOT a happy day for the gun owner.
