Barrel question for you all

[FROGO207]

I have a friend that has a barrel he got for a deal at an estate sale and is unsure what it is threaded for. It is a 30 inch SS bull barrel chambered in 300 WIN MAG. The threads are 16 TPI triangular type, diameter 1.030 inches. The length from threads to shoulder is 1.185. I am thinking it fits a Winchester receiver possibly. I do not have a barrel to match it up to here so asking you all. Do any of you recognize what it might fit. He would rather get a receiver it fits rather than start from scratch with it.

Does the breech have a recess? It sounds like a Remington 700 bbl, especially if it has a .700 x .150 recess. Remington's are 1.0265" 16 tpi while Winchester and Ruger are 1.000" 16 tpi but the threads are way too long for any rifle action I am familiar with. A Savage or some other action that is set up for a nut would have long threads but no shoulder so I'm stumped. A picture might help.

A Savage barrel can be set-up without the nut, using a shoulder to bear on the recoil plate/receiver as in the Remington 700 - and I've done several rifles that way. The thread pitch and diameter are not correct for the Savage, though, and the closest to the dimensions given I have a reference for is the Weatherby Mark V magnum - even that is not exactly the same, and the shank length is much too great in the barrel you have. I suspect the barrel is for one of the custom benchrest/match singleshot actions.

I have not looked at the barrel yet. I will see about that picture as well. Might well be something custom as it was from an estate sale buy.

I don't know, it doesn't match anything in the back of DeHaas, but that is not a complete listing.
Buy an action to fit a barrel, eh. I read of people buying guns to suit ammo or loading dies they got cheap, more of the same.

 

[FROGO207]

Yeah probably best off to buy an action and have the barrel fit to it and rechambered. You know how it goes when you find a deal and try to make the best of it though. I think that it is his first from scratch build if you don't count AR's so anything I can do to help will be appreciated I am sure.

Any indication of the make of barrel?
I would not go to the trouble of building a rifle around an unknown.

It sounds like a Remington 700 bbl, especially if it has a .700 x .150 recess. Remington's are 1.0265" 16 tpi while Winchester and Ruger are 1.000" 16 tpi but the threads are way too long for any rifle action I am familiar with.

I'm guessing you meant to type 1.0625.

1.030" major dia and seemingly 16 pitch sounds to me like 26x1.50mm; 26mm is 1.023", and M1.50 pitch would be 16.9 TPI. If they are truly 16 TPI, I'm not aware of any rifle that's 1-1/32" 16 TPI.

Howas are M26x1.50, but their tenon is even shorter than an M700 and the recoil lug is part of the receiver, so that's unlikely.

As stated, pictures would definitely help.

On that note, I don't know what the "deal" was, but most take off barrels are dirt cheap, so he should worry more about the rifle he wants to build. I just grabbed a new take-off .300 RUM barrel on eBay to build a test rig, cost me $60 shipped. Also understand that barrels not using a Savage style nut are fitted to specific receiver and bolt to set head space; even if you figure out and acquire the receiver, his "good deal" barrel will most likely need to have the tenon cut a little longer and then be trimmed and reamed to set headspace. Trying to build a rifle around a take off-barrel you got would be like building the car around an engine you scored on the cheap.

He didn't say what he paid for it. It is a Hart barrel and he contacted them. They had a fire and all records but recent ones have been lost. He has come up with a Mauser action and he is going to have the barrel set back, threaded, and mated to that---then reamed in 300 WIN mag again. Sounds the best option to me. Thanks again for your input guys.
