Interesting 7.65mm measurements

[Hugh]

As requested by Unspellable, I took measurements of some of my 30 Luger bbls.


Looks like 32 cal (.312) bullets might be the ticket afterall! Here are the results of my measurements. All measurements were taken by driving a cast 32 cal bullet thru the barrel, then measuring with a micrometer.


.309= New Numrich; Bulgarian arsenal rework

.310= New Swiss bbl; unmarked old 6" bbl

.3105= Browning HP

.311= 1970's Mauser Luger; Ruger P89

.312= Colt Commander; 1923 Commercial Luger; 1906 DWM Commercial, 1900 American Eagle DWM; new "Made in Germany" bbl.

I've seen some so so military shooters do very well after measuring the bore and getting the bullets to match. Buddy of mine a few years back loaded his own for a Portugese mod 98 and used to win high power competitions over high dollar guns with it using open sights at 500 yds. Granted, he could shoot but the gun was excellent. Really used to upset some folks.
