what would happen if a 50cal rendered safe is filled with water then frozen/ heated?

I've always wondered what would happen.

I am referring to those souvenior 50cal bullets sold in some shops especially in europe. most have a hole drilled in the primer cap.

What if the cartridge is filled with water, then the hole is thread and a large bolt is used to seal it, the cartridge is then heated with a flame or placed in a regular home freezer.

assuming no air inside

Speaking theoretically, the bullet would pop out if it was heated enough to generate sufficient steam force. Theoretically again, freezing causes water to expand (increase in volume which, given no other room for expansion, should push the bullet out.

Haven't you ever made the mistake of heating a sealed tin of beans over a camp fire, or put a can or bottle of soda in the freezer and forgotten it? Trust me, doing either is a lasting memory.

I thought so too some forums think the walls bursting open.

How much pressure is required to seat the projectile anyway?

The easy, not trying to be funny, answer to how much pressure is required to seat the projectile is 'not that much'. .50BMG cartridges can be hand reloaded.

MY apologies. I posted a link for an 11 minute long .50 BMG reloading video on You Tube. Try googling '.50 bmg reloading'. You should get it.

No worries!


'any rough idea of the pressure required?'
I could only guess that it would be about the same as seating a .308 bullet.
