I was given a Winchester 670 in 30-06, but without a bolt. In looking for a replacement I've determined that a complete bolt assembly is about three fourths the total value of this particular rifle. The barrel is in good condition considering it came out of an Alaskan native village(which I suspect is where the bolt may still be), but I'm trying to determine if I would be farther ahead sending it to Winchester and having a new bolt installed and headspaced, or taking my chances finding one myself online and having a gunsmith fitting it up, or third option, selling it off for parts. I hate to do that as I really wanted to keep it as a shooter. Any suggestions would be most helpful. Thanks

There are at least 2 bolt types for the 670. Both are push feed types. The early ones did NOT have the anti bind slot throught the bolt lug.

Good luck finding a bolt but occasionally one turns up. Either style will work. Grind off the anti bind slot if your rifle doesn't have it. I am surprised that Winchester, which is not the same Winchester that built the rifle, still will fit bolts to old push feeds. If you have something else to shoot in the mean time, I would try to find a cheaper bolt.

The current Winchester is not going to do that.
I would locate a proper bolt myself and by doing a serial number search, determine what year your rifle was made. That should tell you what bolt to look for.
Dont trust just any smith to do this. Not a slight on the profession at all, but not all smiths are competent. Way too many local guys hang out the shingle but can do nothing more than screw scope bases onto a receiver.

Thank you for the responses, When I call Winchester(about a month ago) they put me on with the floor manager in the action dept, I explained the situation, and he simply asked me if the serial # started with a G, which it does(G234050) and he promptly told me that they could fit it with a new bolt. Of course that was without the rifle in his hands, so he could not quote me a price until I sent it in for evaluation. I don't know for sure what the anti bind slot is, yet!

I'll take a pic of my old 670 bolt face. Does your rifle have a trigger safety or is the safety on the bolt?

Rich

No safety on the rifle itself so must be on the bolt. Some time back I bought a bolt body off of e-bay, that is supposed to be for a post 64 mod 70. It came from a gunsmith estate and is just a bare bolt body, and the bolt face must not be completely machined yet because it will not feed into the receiver as is due to a wing in the receiver that the bolt face is not slotted for. I'll try to get a pic of it on here if I can.http://flic.kr/p/hgkUtp http://flic.kr/p/hgjPhs

I just looked at the pics of your bolt; it is an anti bind bolt that has not had the slot milled into it; probably/possibly not heat treated either so do not shoot it. It would be simple to mill the slot into it and make it fit but only after you determine if it has been heat treated. Those bolt handles are brazed on, and I assume all milling would be done on the bolt face before heat treating. So, keep looking. That wing on your receiver is for the anti bind slot in the bolt; now you know which bolt you need. Here is a pic of a bolt with the anti bind slot in it. And the receiver slot. An early bolt should fit into a later receiver.

Thanks, I will keep looking. If all else fails, I'll send it ti Winchester, or make a lamp stand out of it. Perhaps I could send this bolt body in with the rifle to Winchester and get the cost of a new one defrayed a bit. I was also gonna add that heat treating would not be an issue for me as I've been a custom knife maker for 26 yrs and I hand forge all my blades and have the set up for doing the heat treating. Wes

I am sure they don't want that bolt, and I realize you have been heat treating knives, but how would you treat a bolt that you don't know the metallurgy of and don't know to what hardness to take it, and what to draw it back to. Bolts are best left to heat treating houses with controlled atmospheric furnaces. But it is your face. Actually, I think they induction hardened the lugs as the bolt handle is already brazed on.

Heat treating for 26 yrs with no returns on product means I've been studying metallurgy for that long, it also means I'm no fool when it comes to doing the research beforhand and knowing exactly what I'm doing. Did you really think I'd guess and take a stab at it??? I'm very familiar with induction heat treating and the sequences necessary for most alloy steels, or know how to find them. I'm not set up for stainless alloys however as I don't have that level of equipment if this bolt were to be of that material base, research would have confirmed this for me!

All the knife makers I know heat treat by guess and golly; I see you are different. In that case, you should mill out the slot in the bolt you have, heat treat it, and use it.

Most of the knives I build are made from ball bearings but I also use a good many different high carbon steels depending on there applications, along with my damascus steel. Each one requires there own recipe for hardening and tempering in a digitally controlled tempering oven. I don't have the needed tooling for cutting on this bolt and I'm to busy forging right now to do research on this bolts needs, so I'm going to stick with either finding one or sending it to Winchester with my fingers crossed.Thank you for your input as I did learn at least what I need to be looking for, regards,Wes

no Anti Bind

A few things to make note of.

The last place outside of the factory to receive and fit NEW factory Winchester ( USRA ) bolts closed up shop in 1995. At that time USRA would not touch the model 70's without the anit-bind device.

The s/n of this rifle having a G prefix makes it a post 1968 rifle, and the cut off for the no anti bind should be 1,050,000 acorrding to the old factory parts lists.

Now that you are no longer dealing with USRA, but Browning / Winchester, in my conversations with several Service centers they can not get hardly any restricted parts anymore.

So IF Browning / Winchester would even accept the rifle ( as they did not make it ) to install a bolt is in question as they may not have the parts needed, as many of those parts got dumped a few years back by USRA.

Any of the older model 70 LONG action bolts can be fitted, and they do show up time from time on eBay or gunbroker etc.

The correct vintage of the bolt would not have the knurling on the handle ( XTR ) but would have a smooth handle.

Used bolts can be found but it will take some searching.

Good luck.

Thank you, good to know valuable info in my search. Wes

dpcd, as more and more knife makers use high tech stainless alloys they have to be precise with time and temperature or they'll never get anything but poor results.
I've been teaching them for years now on various forums. [Mete means metallurgical engineer }

Do you know the date of manufacture of your Winchester 670. The couple I've recently looked at had safety on trigger not bolt shroud. These were 1975 and 1976 vintage. Perhaps you could post a picture of the bolt handle side of your receiver/trigger group. Let me know and I might be able to help you out. Ron
