So seeing as your sure the bolt was locked can you explain how it showered you with debris? The case, it's head and all the cartridge components would have been secure within the chamber, it's possible if the two separated that some gas may escape backwards but not for debris to do so, are there any remains of the head?

 

I agree your message to wear eye protection is valid, but so is my message that what you have is most unlikely to be a fault of the cartridge, and no I don't have any affiliation with Gamebore or any other cartridge manufacturer.

I have a varied engineering background and a good understanding of the workings of most firearms, in my opinion both the cases reported here the cartridge was at fault. The firing pin cannot go forwards once the bolt has started to retract so that only leaves a hangfire as the cause. I myself have had my first hangfire this year after tens of years of shooting so perhaps there is a clue in the fact several people all of a sudden are having them.

 

Anyhow in the case of a hangfire with a semi if you are pulling the bolt to clear the chamber when the primer finally does its job then you will get what the OP had happen to him. If you have a hangfire with a break barrel gun and open it to expose the brass and it goes off you could end up with the brass in your face .

 

This issue should be dealt with by the cartridge maker giving fair compensation, I would expect to be able to return the whole remaining quantity to the place of purchase and be compensated for my travel and reasonable time costs along with the purchase costs involved. If they give you 4 boxes for one returned you have been ripped off as your travel and reasonable time costs way exceed the cost of 3 boxes.

 

The sale of goods act covers compensation so it is Law and not opinion.

I'd agree, but......

 

I see what your saying, but it went off before i touched the bolt.

 

 

And that being the case this still stands

My opinion would be the bolt failed to lock up properly, that being so also answers other questions ... debris ....stuck wad..... jammed cartridge Edited by Paul223

The plastic case is only there to hold all the components together for ease of use there is non or very little structural need for it.

 

So to blame the case for the problem is a no go.

 

So if you did not touch the bolt even after a hang fire the cart is still locked in the chamber of the gun as there was no gas presher going down the gas port near the end of the barrel to unlock and cycle the action to extract the cart and reload the next cart but for some reason the bolt has came undone after you tilting the gun over and just prior to it giving a full ignition thus giving a rupture Of the case and loss of gasses out of the chamber.

 

There is only 2 answers hear

1 it happen as you pulled the bolt to remove the cart.there is nothing to be embarrassed about as it needs to be made safe..

 

2 there is a falt on the guns action which allows it to be shot without it fully locking up or it don't lock up at all.

Sorry I missed that post re not touching the bolt so we seem to have a hangfire and a not fully locked bolt ? .With the bolt partialy retracted the hammer cant hit the rear of the pin so also there is a possibility the powder did not burn at the correct rate causing the bolt to be pushed back slowly and the increase in pressure with a partialy extracted cartridge caused the incident. Either way I still think it is a cartidge issue.

I think fruity is on the money when he said turning the gun over, it's a rotary locking bolt, maybe turning the gun on it's side ~ released / free'd / allowed to line up ~ something on the ~ bolt / hammer / pin ~ whilst the bolt was not fully locked, may be something as simple as some dirt / debris stopping the rotation of the bolt head? Which now would no longer show as a problem.

I could go with that one, I did not know it used a rotary bolt.

yep, its a rotary bolt head...

 

i think that may well be a viable reason to be fair guys, and in all honesty that hadnt even occured to me!

 

feeling a little sheepish now as the rotary bolt scenario wasnt something i had thought of.

 

i'll go home and have a look this eve and see if when i flip the gun over the bolt moves at all.

 

:good:

My Benelli M2 has a rotary bolt, and in all fairness it's very easy to get the bolt out of battery. The slightest knock will do it. Common across all of them, however its something they have fixed with the new Raffello Black and wouldn't ordinarily be a problem.

 

Combined with a light strike though .... :/

 

I agree it's the most plusable senecio

Listen to fruitloop guys he's talking sense, Brett yours is most likely a gun related issue, posting pics to Gamebore's Facebook isn't really going to get you anywhere, it's quite obvious that ignition was happening/happened outside of the chamber and that the bolt was not closed / locked.

Weeneebs yours is a cartridge failure, it's very unlikely the cartridge fail would have resulted in the case being pushed down the barrel too, pressure from the gasses expanding within the cartridge would seal and effectively grip the chamber walls, When you think about how many cartridges are used each year it really is a miricle we don't hear of more defective cartridges / cases.

as i said i was using my auto next cart rammed faulty cart up barrel yours weeneebs /phil
