Mosin-Nagant Mishap

The Provo City Shooting Sports Park gun range in the local canyon recently had a mishap with a Mosin-Nagant. I haven’t volunteered as a Range Safety Officer on the city managed range in close to a year, so I wasn’t there at the time of the incident. I don’t have enough information to speculate seriously but maybe someone else recognizes the state of the cartridge in the photo.

We had a gun/ammunition accident at the range Saturday. A 7.62x54R cartridge exploded, causing damaging a shooters hand. This is the second time I’ve seen this problem. However I can’t find anyone on the internet that has had this problem. Attached is a picture of the cartridge in question. The primer had not been hit. Most of the bullet was still in the case, part of it did hit the 25 yard berm. The shooter is having metal taken out of his hand, wrist, chest and throat today.

If anyone has any knowledge of this kind of problem, please let me know. If you have any contacts that may have seen this problem let me know. I am taking suggestions on what to say in a training script, so we can work the problem before it happens again.

  1. What are your thoughts on it being from Rim lock? Did the cartridge get smashed hard? I was up there that day after it had happened. “G” had mention they were putting lots of pressure on it. My Guess: Gun was loaded incorrectly causing rim lock. rather than opening up the magazine and letting the cartridge fall out they smashed causing the round to go off. Thoughts?

  2. There is no controlled feed on the Mosin-Nagant rifle. What the shooter did, was push the bolt forward, picking up the top cartridge from the magazine, and chambering it. Then, the shooter got distracted somehow. Assuming the rifle was unloaded, the firer pulled back the bolt, without having locked it first, which would have forced the extractor to snap over the rim of the chambered cartridge. The shooter then introduced another cartridge into the magazine, or the bolt raceway, shoved the bolt forward, and had the cartridge in hand above detonate the chambered cartridge. The chambered cartridge exploded, probably sent the bullet down range, and produced all of the metal fragments from the steel case. The cartridge pictured is the second one, that detonated the first, hence no obvious shrapnel pieces missing. The telescoping of the bullet and case was caused by the explosion of the chambered cartridge against the forward pressure exerted on the bolt.

    There are legions of North American shooters that literally have only ever fired self-loading/semi-auto firearms. The bolt action causes these folks problems, much like the injury sustained by the firer in the photo.

  3. Internal primer compaction, its the reason we dont use berdan prime anymore. the chamber had a piece of case from the previous round breaking a piece off in it, they tried forcing another in causing bullet setback into the cartridge compacting the powder and setting the nitro off in the berdan primer, no strike but spent, seen it happen mostly on MG’s where case sep happens more often. saw and afghan Army Soldier showing off and the same thing happened. he was trying to keep up with an American running a Remington m24, watch it come apart as he reached for the round to clear the jam.
