Anyone ever heard of an HK barrel bulging in the middle? Muzzle and chamber ends measure .447" roughly the middle is roughly .452". (I say roughly because we don't have cool guy measuring tools)

Did someone fire a squib load through it?
Don't they use cannon steel for their barrels?
How are you measuring down to .001 inch without cool measuring tools?? You're talking about resolving a .005 differential.Originally Posted by wmu12071
Realistically, they aren't supposed to bulge. Will put a micrometer on mine when I get home and see how it measures along the lengths.
I don't think it was squibed. I was at the range with him and was loading mags at the time and everything sounded normal.
Measured with calipers. Micrometers etc. Were not available when the barrel was available. I only said that because I have read a few post from Bill Riehl my tools are like drawing prints with crayon by comparison.
