Sorry if this perennial problem bores you folks....but maybe someone can clear me up on this..
I have a rifle supposedly chambered for 7.62 NATO....and of course I want to shoot commercial .308 Winchester in it....
I had the head space checked with .308 SAAMI guages and the bolt closes on the GO guage...and won't QUITE close on the Field Reject.....1.0030 and 1.0038.
I don't intend to shoot reloads in it so it should be fine as is..but...the rifle has that Savage barrel lock head spacing system..
I was thinking of having a gunsmith tighten the thing up a bit to get it more in line with SAAMI .308 specs...That is ...shorten the chamber a bit...
As I understand it...the Nato 7.62 chamber is made purposefully a bit large to accomodate variations in military ammo...so they all will at least chamber...they get away with this because the brass is thicker and can take the extra expansion..but I probably wouldn't be firing mil surp ammo anyway.
Is my thinking correct on this....would the head space adjustment do what I want ?....How much is involved in this...
Thnx...
Oh...the action is considerably strengthened and their should be no problems with pressures...
