What Happened

[tusker]

Picked up my cartridges after a drive. i noticed these 2 . Any idea,s what happened. I didnt notice anything when shooting there were at least 20 shots fired on this peg.

Shot stuck together? I saw something similar when a mate was using steel that had got a bit damp

 

[Liveonce]

not uncommon in .410 and 28gauge especially if fibre wads, the friction of the wad against the case wall is likely the reason, being sufficient to stretch the plastic breaking part of it away.

what cartridges was you using.

 

[Smellydog]

Too fast a powder.

 

[ashray]

the age of the case ,plastic used becomes brittle after a few years

 

[andyk]

How old are they? I’ve not seen Eley doing a RTO on their cartridges, other than some really old ones I got given. All the new ones I’ve bought since 2019 have been crimped.

Mouse in the barrel?

I used to find Hull High Pheasant in .410 would remove a good portion of the end of the case, almost every cartridge xxx

Please pardon the very elementary question - the gun presumably has 70mm chambers? I ask because the inside of the case at the mouth looks as though it might have been in a forcing-cone. I see something like this this when using 67.5mm in 2.5" chambers - but the bit which looks abraded is shorter, reflecting the very slight over-length of the case.

I see something like this (not the lumps of case missing, I mean!) this when using 67.5mm in 2.5" chambers - but in that case the bit which looks abraded is shorter, reflecting the very slight over-length of the case.

I thought the same

 

[Liveonce]

The .410 may look small, puny compared to a 12gauge but they operate at a much higher pressure than a non magnum 12ga cartridge, 850bar vs 640 for a 12gauge.

I had that donkeys years ago.........some ancient .410 carts where inspection (after the event....) showed the shot appearing to be stuck together into a whitish solid lump.
The bunny was almost in two bits...

2 years old

Chambers and cartridge 70 mm

Eley high game fibre and they are crimped

Eley high game fibre and they are crimped

Just a thought, I had some VIP in 20b a couple of years back where the cases were uneven in length (when fired, one side of the cartridge was longer than the other, as if the plastic was cut at an angle). It didn’t seem to matter in my gun (70mm cases but 75mm chamber).

Perhaps these are the same and the ‘long’ side has taken the length over 70mm, causing some of the crimp to end up in the forcing cone and so has been torn off.

What gauge, I assumed 28 gauge as 24gm and not it a yellow case. ?? but may have it all wrong.

 

[enfieldspares]

Nothing happend that is the fault of the gun. I had the same with a box of Hull Cartridge Company 3" .410. Fired in a 76mm chambered AYA No4 .410". As others say the wad is stretching the case and that, plus likely a "hot" (in temperature) powder has given you what you see. The annoying thing of course is that the cases then are useless for reloading. Contact the shop where you got them and Eley. I am assuming that the OP's cartridges are 28 bore as they are marked 70mm.

Let us know on SD, please, what the reply was.
