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.
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 (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.

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

Eley high game fibre and they are crimped
What gauge, I assumed 28 gauge as 24gm and not it a yellow case. ?? but may have it all wrong.Eley high game fibre and they are crimped
