Re: USMC Mod 70
Pg 160 Complete Book of US SNiping indicates that the Unertl 10x was in fact used, IN KOREA.
to quote:
"As a result of 1000 yard shooting, during which sevral "Chi-Com" casualties were registered, the .30-06 Winchester Model 70 Bull Gun (28-inch barrel, .842-inch Diameter muzzle), mounting a Unertl 10 power, two-inch objective telescope, was considered nothing short of phenomenal.
So is it likely a few of these went to Vietnam? Possible.
Also noted that both the target stock and the standard hunting stock were used in Vietnam, one photo shows both in use at a range.
Interesting to note, pg 168 on "The complete book of US Sniping" there WERE in fact several 3x9 variable power "Marine Scopes" mfg'd in Japan used on the Model 70, and one photograph to verify.
