3095 out of battery discharge

712 Views 22 Replies 8 Participants Last post by  cicpup
I've ran about 70 rounds through my 3095. Had some feed issues, about a round per mag at this point, using Federal and Remmington 100gr fmj ammo.

Just today had an out of battery discharge... ugh.. so I guess I'll be contacting support tomorrow morning.

Judging by how far forward that case is blown out, it discharged pretty friggin' far out of battery, too. Did that happen after you pulled the trigger or as you chambered the round?
Did you by chance change anything like springs after you bought it? Aftermarket parts?

As I pulled the trigger.

No aftermarket parts at all. Still with the steel sights too.

Well that's not good.

5 possibilities come to mind.

First two are defects with the firearm.
  1. The firing pin may have been stuck forward. This happens sometimes if gunk or detritus such as lead/copper/brass shavings get caught in the firing pin channel. This seems unlikely because it usually causes a slam-fire or even runaway fire and you described this as happening when the trigger was pulled.
  2. A slight defect in the tolerances which could allow the sear to release even when out of battery; something which is not supposed to happen. This would require some other issue during the chambering cycle which left the cartridge not fully seated in the chamber and could work in conjunction with the three other possibilities.
The next three are ammunition related.
  1. An over-pressure cartridge. It might have been accidentally loaded to pressures exceeding SAAMI max for the .30SC.
  2. A defect in the brass wall of the case making it weak and susceptible to blowout. This can happen if a case is reloaded too many times but can also sometimes happen with factory new cases.
  3. The bullet may not have been set deep enough, causing the bullet to engage the rifling too early and create a pressure spike. If it is setting too proud it could theoretically prevent the cartridge from fully seating (the 30SC headspaces by the case mouth resting on the chamber shoulder same as the 9mm and 380].
    1. A variation of this is the opposite, where the bullet is seated too deep in the cartridge which leaves too little space in the cartridge for combustion, again causing a pressure spike. This is often caused by repeatedly chambering the same cartridge which pushes the bullet deeper in but can sometimes be caused by a defect in manufacturing which slips by QC.
    2. Another variation is that some tiny bit of detritus could have lodged on the chamber shoulder causing the cartridge to very slightly protrude. This could be enough to cause the out of battery condition during discharge.

The fact that the blown out cartridge also has a pierced primer makes me think this was some how an over-pressure cartrdige or had a pressure spike from a mis-seated bullet. Was this ammunition reloaded, from a questionable source, or from a sketchy manufacturer?

Your over-pressure theory is pretty sound and may be better than the out-of-battery detonation theory. The OP can test the theory by putting a spacer in front of the breach block to see if the weapon will dry fire without the action being closed all the way. If it doesn't dry fire at the first amount of opening, then the OP can progressively decrease the spacing until the weapon dry fires out of battery.

He may very well end up discovering that he won't be able to create an out-of-battery trigger brake, which would effectively prove the over-pressure theory.

The nice thing about Hi Points is that they don't seem to be affected by kabooms. Demolition ranch has had to effectively turn his Hi Point test subjects into pipe bombs by screwing bolts into the muzzles to cause permanent damage to them.

The primer isn't just a little pierced either. It looks like a rocket tried to lift into orbit through it!

Ammo.. factory ammo, Remmington UMC 100gr FMJ 1250 fps.

I think its most likely related to the extractor. What makes me think that is looking at the pic with both a spent round and the round that detonated in the ejection port.

hmm.. well that makes it less likely but still not impossible. I'm still thinking ammunition failure to be honest.

I suppose anything is possible but I really would doubt that. It still looks like ammunition to me.

The firing pin could of been stuck out.

I’m thinking firing pin too. Not sure what an extractor would do to cause that.

The reason I wouldn't blame the extractor is because the next round is still engaged under the extractor claws like it should have been. If the prior round hadn't blown up, then that bolt block would have gone the rest of the way forward and chambered the second round, with the case rim held by the extractor claws.

Interested in what HP says. Probably want to take it back for repair. Could be chamber depth?

Probably not since he has had 70 happy bangs.................

Called them on Tuesday.. sent emails upon request. I was told I'd need to talk to their manager and that he'd call me back.
Well, never did did get that call back...

And....Twice now I've called in the afternoon only to have their "we're-gone" message on--hours earlier than their own stated hours. Geesh.. .

Since they're closed on Fridays and no doubt not there Monday for the Holiday, it'll be Tuesday until I can get ahold of someone again.
Any news?
