I have a 20+ year-old Win M70 HB/synthetic that I've mainly used as a hunting rifle. I bought it from a guy in 1994 that bought it to shoot bench but didn't like the recoil and was going to something smaller like a .223 or .243. I would say the round count on my part is 300-500 and it was almost NIB when I got it. It shoots well, probably better than me, but I would like to know whether or not this rifle is worth investing more dollars in, such as cutting/threading the barrel, cerakoting, upgrading the stock/scope, etc. and turning it into something that will go 600-1000 yards with consistent accuracy. I have a place to shoot so that isn't a problem-I will be shooting it and will be handloading for it and others eventually. Am I better off starting over and mothballing/selling this one? What can a gunsmith tell me about its measurements and what would that cost me? TIA.
