Sounds like a hawken, more than likely a 1"48 twist. The last two digits on the barrel is the year. there should be the serial # and then 2 more numbers, those last 2 is the year. And thats a 10-4 on the beech wood stock. They turn out beautiful once you take the ugly factory finish off and stain it darter and a few coats of truoil.My brothers loves 80 grains RS and a 295 powerbelt for hunting. PRB is also deadly in the rifle.
