Winchester 670a 30-06

[RNE228]

I have been shooting one that was reamed out to 30-06 Ackley Improved. Nice shooter. Has taken deer and elk.

I would place rings on your rifle scope that allow for the minimum necessary bolt clearance.

I would place rings on your rifle scope that allow for the minimum necessary bolt clearance.

Excellent advice. I started out with low rings on my Model 54. Looked great. And the bolt handle did barely clear the scope if I worked the bolt slowly and carefully. But I found that if I worked the bolt quickly there was enough wiggle in it to scrape the bolt along the Redfield occular's knurled rings. Didn't like that at all, so I had to swap to medium-height rings.

Just for illustration, here is what I was talking about regarding the ring height I had to go with on my Model 54. A low-ring setup was ideal for shooting ergonomics, but I had to swap to these Med rings for comfortable bolt clearance. Probably wouldn't have been and issue except that those trademark knurled rings are like having a big rat-tailed file back there. It cleared just barely if I worked the bolt slowly, but I put some scratches on my bolt handle just from working it quickly a couple of times. If I'd used a Leupold maybe, or something else with a smoother finish on the ocular bell it might not have been an issue.

FWIW, the Vortex scopes I've seen and owned have kind of a fat ocular for their sizes. That would also require taller rings.

Can anyone tell me how old this is serial number is G203xxx

Anyone able to help him out? I searched but couldn't find a listing of W670a serial numbers. And I was looking on Winchester's "When was your Winchester made" page. I searched for Model 70 with SN "203111" and it came up as 1951. Can't be correct of course, since the 670a wasn't being built until 1966.

Unless the 670s were made from old inventory? Is that even possible?

As Ki6vsm states, there does not seem to be a record of 670 serial numbers. What I did find though is that the "G" serial numbers are from the last model update and had the superior action and it was a much sought after action by builders. You made a good deal, now go out and shoot it and enjoy it.

2010 quote from a post on HuntingNet.com:

"The original version had feeding problems, the bolt would hang up, sometimes. Look for a Win.670 with the "G" serial number. This was the final 670 version. It is smooth. The right hand locking lug has a groove in it that follows a rail on the inside of the action, so it does not and can not do anything but be buttery smooth in action. Many Bench Rest competition custom rifle builders buy this rifle for just the action. It is that smooth."

Not sure whether my 670 is an A model or not but the serial is G1113175 if that's any help. Probably built in the early 1980s.
