Odd things that can go wrong 3

With your 1911.

What happens:
When they made the barrel, the did a horrible job on the head spacing.  It head spaces on the cartridge rim, so if you bore that chamber and extra eighth of an inch...  Not in spec.  But you find barrels like this.  Old ones, especially.


What this causes:
Often?  Nothing.  The extractor hold the case against the breech face and the firing pin can get to the the primer and do it's thing.  The pistol appears to function fine...  It's still not good, per se.

    If it's a .38 Super, it plays Hell with accuracy; and the Super was supposed to headspace off the rim.

    That's changed to the case mouth now.

You can always offend hippies in the comment section. Chances are, those will be held up as a proper example...
