"Water can be compressed? that's news to me."
There is a reason when you bring fish up from very deep water they all turn inside out.
they have to be kept in a high pressure container to survive.
Steel compresses also.
it is all about how much pressure you want to apply.
Water behaves very differently at 60,000 PSI than you would think.
The steel in a rifle receiver stretches enough on firing to use strain gauges to determine chamber pressure.
ETA:
Electrical tape works well for covering barrels.
Just shoot through it.
The air in the barrel in front of the bullet is probably going to make a hole in it before the bullet even gets there.
I have done this with even .22-250 rifles with sporter weight barrels with no problem.
