When I did my small engine course at tafe a couple decDes ago - the teacher bought in a Holden red202 piston that was cracked in half. He told the class it was from a hydro lock with an estimated 50mls of water being in with some petrol at start up. He was proving to us the dangers of non compressible liquids and it has stuck with me.
How much water can fall into a barrel from rain over a couple hours on foot ? I really don’t know - but if I squirted even a minute 5mls in the barrel, left it for 10 mins, would you be happy to put you face near the breach knowing the pressures? I’m not sure thus the question.
Think I’ll try the tape grouping for piece of mind and see how it goes.

Hydraulic lock by definition involves liquids, not air.

But again im not advocating giving it a go...
No shotguns fired into pools of water here...
Marksman...its a shame there wasnt another camera pointed at all those guys faces above the water when that shotgun exploded...some serious WTF expressions along with a little leakage im sure...!!
An extreme example, but a good one none the less...
And thanks Marksman...

The receiver won't blow up unless the case fails spectacularly. The pressure is between the bolt face and the blockage in the barrel, and the barrel is almost always going to be weaker than the receiver.
I'm curious if there would be a difference between 150mm of water resting against the shell, instead of the 400mm airgap between the shot and the water. Pour the water in whith the barrel pointed upwards and I think it would just have horrendous recoil, without damaging the barrel. With the muzzle in the water, the water in the barrel has nowhere to go, so it's easier to split the barrel.

Maybe we should all pitch in for a cheap as chips but functioning rifle for you to conduct the "will it or wont it" experiment...

the biggest concern to think about is how much water went in
its no different than over oiling and not patching the oil out will cause erratic groups as well as barrel bulge or safety concerns
in a shot gun you can blow the barrel

I have watched a demonstration by belgian armourers who put fn scars in wheelie bins of water took them out gave them a shake and fired them
but that does not mean I will soak my rifle in water then shoot it
the tape idea is for litter that will stop obstructions but would work for a bit of rain
forgot to add goodonya Stix

There is some pretty good footage of an AK47 firing submerged in a swimming pool, the pressure wave precedes the bullet. The slo mo shows this clearly.
