Anyone know anything about this?
There was a thread on the Bullseye list about barrels blowing up - and someone mentioned this "This same problem has recently appeared in Kimber 45's with the Chip McCormick barrels that are made in the Philippines. They too are starting
to blow. Not all Kimber's, just the ones I just mentioned. It seems that
those chambers were also cut short and throated too deep and the same
problem is present. The problem is, you cannot tell, unless you take the
time to check out your barrel, whether on not that you have one."
I asked how you can determine if you might have one of these barrels and got the following reply "Thanks, and here is the answer to your question.
Disassemble your Kimber. Make sure the magazine is removed and check to
make sure that the gun is not loaded (my liability speech). Remove the
barrel from the gun. Drop a sized or new case into the chamber. View the
amount of exposed case at the base of the chamber. Pull the case out of the
chamber until it is flush or slightly (.001-.002") beyond the hood. Now,
with a felt tip or fine black marking pen, trace the chambers mouth at the
bottom.
Remove the case, is the side wall of the case exposed? How much side wall
is exposed above the web?
The more exposure, the greater the risk and the better the chance that you
will have a blown case, eventually. No one knows when!
I suggest that you purchase one of those Bruce Martindale [email protected] brass gauges. Check both new and 1F cases. Note the bulge."
