VH 28 stuck shut.

[Researcher]

I've got the same problem with my 28-gauge Model 12 Skeet Gun. I shot it in competition with the early compression formed AAs from 1973 to early 1977 and it worked fine. Modern AAs and STSs are very hard to close on and then even harder to eject. I took an old box of paper Winchester Super-Speed 28-gauge loads from my ammo collection and shot a round of skeet with them with no issues. The rims on those shells were visibly thinner than the modern shells.
