I had a similar incident happen to me today using the standard velocity CCIs and a Ruger precision rifle and 1022 magazine as well. But it wasn't an outer battery detonation around in the magazine detonated while closing the bolt The round in the chamber came back out on fired and fine and there's still around in the magazine. Appears that the round detonated inside the magazine, blew the magazine apart and broke the side of the chassis.Last week at handgun league, I was marking targets when there was a loud detonation on the firing line. The RO called a cease fire and asked if the shooter was ok.
The shooter had pulled the trigger and along with the loud report, the magazine had blown out of the pistol, with powder marks on the shooters hand. When we cleared the pistol, there was a headless case stuck in the chamber, we never found the case head. The detonation actually severly dented the cases of 2 unfired cartridges in the magazine.
We wrote it off as one of those things that happen but we have had a second incident this weekend. Both shooters were using CCI Standard Velocity 22LR ammo in blue 50 round boxes. A group of us bought a batch order a couple of years ago.
One of our shooters was using his Ruger 10/22 at the range and he had a detonation that blew the magazine out of the rifle and left powder marks all over his hand. The force of the detonation blew a chunk out of the side of the rotary magazine. The case head did not separate but was cracked open around most of the base of the rim. The lot number of this ammo is H21CA10. He had fired about 100 rounds when this occurred.
Attached are pictures of the 10/22 incident and I haven't received the pictures from the handgun incident yet or the lot number of that ammo.
Trying to find out who the Canadian distributor is for CCI ammo so we can flag the issue with them, as well as CCi.
