How much pressure do primers produce?

[amlevin]

There any pressure data out there by chance?

Do your own testing. Load up a series of cases using the same bullet and COAl. Just use a different primer for each and leave out the powder.

Fire the case and then run a piece of doweling down the bore, marking it where it enters the crown. Push the bullet out of the bore and repeat.

The one that pushes the bullet farthest into the bore is the "strongest". Just keep a nice long brass rod handy to knock the bullets out of the bore should they actually get that far. Pistols have more of a problem than most rifles with large empty cases.

A Badddddd suggestion...

Keep in mind that the bullet it a metal bar that is substancially LARGER than the hole in the pipe in front of it - if you get the bullet into the barrel, and it stops... it will NOT ever come out because of the Blish effect (kinda like a bullet's version of a roach hotel).

A good friend has a classic Winchester 1894 with a bullet in the barrel, and he has used wood, and steel rods, heat, oil, and even voodoo dolls, and the bullet has not moved a millimeter!

There was probably a small amount of powder in the case for the bullet to get stuck that bad.

I've fired cases that had only primers and bullet in them, no powder, and the bullet didn't even get driven into the lands. This was with a large rifle primer in a .308 case. Yes, the primer fired as it covered the boat-tail of the bullet with soot.

In short, the larger the cartridge, the LESS likelihood the bullet will be driven into the barrel at all from JUST PRIMER energy.

No, I'm not talking about pistols were the case is smaller in volume and the primer can act on the bullet with greater energy.
