Default A small experiment

12 gauge shell after firing with scope mounting holes drilled through into chamber. As you can see it barely shows where the holes were and ejected normally.

Years ago I had a .32 rimfire that had a bolt hole into the chamber for the bolt that held the trigger mechanism to the barrel. I put a very lightly greased cartridge in the chamber and then pushed some "plastic steel" in the hole and screwed the screw it. That eliminated the problem of the case pushing into the hole. I doubt it would work well for a high pressure round, but for a shotgun shell it ought to work well.

If I intended to use the original chamber I would do something similar Gene. A little dab of JB Weld in the hole from the chamber side and you would never know the difference. This one has a very rough bore and will be used for a glue in stub job.

I have often wondered about the integrity of the metal if a hole was drilled too deeply . Guess this puts that to rest!

I think it is related to the size of the hole. I feel pretty sure that a 3/8th or 1/2 inch hole would blow the case out at least.
