I have obtained a Winchester 92 that was rebarreled to 357 magnum in the past. It has a bulge in the barrel aboutI 2" ahead of the forearm seen in right light but more readily felt. I have access to two 92 Barrels one in 25-20 other in 38-40. Question is can I go to an octagon barrel its round now. And Since its 357 maybe I should go with the 38-40. Of course I’ll need to find someone to do the swap then.
Thanks for any advice/help.

John,
There is a difference in the receiver frame for a 25-20 or 32 WCF, and one in 38 WCF or 44 WCF. Specifically, the magazine tube is larger in diameter for the larger calibers, and the hole milled in the receiver for it is larger. You can not install a 38 WCF barrel and magazine tube on a rifle that was originally a 25-20 or 32 WCF. I suspect that your Model 92 was originally the smaller caliber.

If the opening/inlet in the receiver where the magazine tube goes is 9/16" to 5/8" in diameter (I dont have a receiver in hand, just a mag tube and follower), then it would be a large caliber 38-40 or 44-40 receiver. If the inlet for the magazine tube is smaller than that above, your receiver is for a small caliber. As for the barrel, if it is round now, your forearm fits a round barrel. To change it to octagon you would have to find forearm milled to accommodate an octagon barrel.
I havent had the opportunity to look at a 92 chambered in 357 but there may have been some alterations made to the receiver ejector, carrier, or guides to allow that cartridge to cycle through the rifle. Others on the forum may have a better idea if the receiver parts would need to be changed or modified from the original. If you could post photos of the receiver, the end of the bolt face, each side on the interior of the receiver, and the end of the receiver where the magazine tube goes, we may be able to come up with some better answers.
Also, on the small caliber vs large caliber, the bolt face, ejector, carrier, guides, and lever are not interchangeable (well maybe the lever if you dont have any problems with the lever spur that engages the carrier dragging on the receiver frame).

Thanks Chris
This is a potential project turning out to be more than I thought/anticipated but that’s why I posted my question.
And finding a barrel forearm etc. would be an interesting search. I’m beginning to lean
toward parting out. It shoots well but accuracy suffers with that bulge. Anyway thanks to all for the comments/help.

Hello, about your post from 4 years ago. I have several antique 1892 winchester, and I would put a 357mag barrel on one of it. Which frame should I take, small or large caliber. And that they are parts modified or inter-exchange frame. Thank you for answering and inform me. 🙂
I have a 92′ that was rebored to .357. I have had it for 40 years, it is very fun to shoot, and fairly accurate. Bert is correct, the majority of these were rebored original barrels and if that is the case it will be a small caliber frame..Chris is also correct in that the guides, and carrier on mine were modified to facilitate feeding. I did further modifications to both in the past to help it feed more reliably, so believe you would have to replace one or both. I too contemplated a new barrel to bring it back to .32 WCF but decided that since it would never be original again why not just enjoy it for what it is and use that money to get an honest .32.. with the 24″ barrel I get well over 1500 fps on even mild loads, which is quite a different beast than the same load through a 6″ barrel… since collector value is lost on that gun, and you will never get it back enjoy it for what it is..40 years ago I picked up mine for $150 and have certainly gotten that out of it in fun…Brian

briango,
Was wondering if you would like to sell the 92 in .357 mentioned above.
Thank you

Grizz, I don’t think I am ready to part with it quite yet, of all the guns I own for some reason my grown kids, spouses and grandkids get more kick out of shooting that one than most anything else….It may only come out to play once a year, but its worth it to watch them shoot it, and I am not burning up lots of obsolete, hard to find ammo like I would with many of my original winchesters..Thanks for the offer though..Brian
