Am a huge fan of the good ol' 30-06, seem to have four of 'em lurking inside my gunsafe these days. Mostly I hunt with the 30-06, and wow - with today's powders and bullets it can do great either on targets or on big game. I've taken grizzly, black bear, elk, mule deer, pronghorn and likely something I'm forgetting with mine. 400 yards on elk? Not a problem.
So it's a 1969 vintage Winchester? A push feed action I'd think. Those actions did great work for high power match rifles, long range or across the course. I used a Cloward built .308 match rifle based on the push-feed Model 70 for quite a while. What a shooter it was!
