I git the 6 1/4" barrel in from Numrich today...I'm somewhat disappointed...
It may not be readily apparent, but the taper is quite 'fat' up where the shoulder is...More so than a 9mm or 7.65mm [100mm/98mm] barrel [first pic comparing 98mm/7.65 barrel to Numrich]...
The Numrich barrel measures .710" at a point 5/16" forward of the receiver flange surface...The Luger 7.65 barrel measues .620" at the same point...
I tapered a home-made 9mm barrel using 7.65 dimension at the barrel band and the point 5/16" from the receiver flange surface (IOW, a stretched 7.65mm taper)...That's it [second pic] compared to the Numrich barrel...
While my homemade tapered & stretched barrel is no show winner, IMHO the profile is much more esthetic than the Numrich barrel...
I don't see why the Numrich barrel was made so 'fat' at the rear...
The 7.65 Numrich chamber is 'sloppier' than my Clymer-reamed barrels...Lot more 'wiggle'...Thread stub is right-on in length and diameter...Bore looks OK...
Flange/shoulder is artillery thickness; not 98/100mm thickness...Numrich front sight band diameter is .008" greater; flange dia is .020" greater; end of taper in front is .018" less...
The dimensions on the Numrich barrel don't equate to anything I have here...In 7.65 or 9mm...Even the 6 1/4" OAL length is odd...
I suspect I'll probably end up re-tapering it...So that it has a 'stretched 7.65 barrel' taper, like my barrel in 2nd pic...
Another Numrich mystery...
