The improved M77 entered the market in 1985. The original M77 entered the market in 1968. Had yours been a standard serial number series, it would indicate VERY early 1985.HOWEVER, the "78-" series of actions were produced in massive numbers in 1978, as a hybrid of the two action designs, with an adjustable trigger only seen on that action series (serial numbers starting with "78-").Your serial number falls roughly into the 1982-1983 date range, but it is impossible to definitively date these rifles. The 78 series actions were used from 1979 through 1991 (even after the M77 Mk II was introduced), primarily on varmint and competition models. But, the actions have been seen on other models as well.Only the Ruger Records Department can properly identify rifles in the "78-" action series (and they can only verify the configuration in which they left the factory).Contact Ruger Customer Service and ask for the phone number to their records department.
22-250, 220 Swift, 243, 6mm Rem, 25-06, 308. Other versions of the 77 were in MANY other calibers.

No, 6mm is not bigger than 9mm; it is actually smaller. Millimeters (mm) are a unit of measurement where a higher number indicates a larger size. Thus, 9mm is larger than 6mm.
