I bought the the exact gun from my 6th grade teacher for 50 bucks. Put a 4x weaver on it and refinished the stock in shop class. It still shoots under an inch to this day.
I had a B in 270 just like yours. I hunted most of the eighties with it. It was an inch and a half gun with factory ammo. I killed three bull elk several mule deer and a black bear with it. The gun had beautiful wood and it’s definitely one I wished I had back!
I killed one at white sands NM back in the 80’s with a Remington Mohawk in 243 One shot. It wasn’t the best choice but my only rifle since the fifth grade.
