I acquired an old Winchester semi auto in .351. I shot it a year or so ago and it functioned fine. Plan to take it apart and clean it up.
Been reading up on it and most say to replace the buffer which is no longer available. Can maybe make one out of something. Suggestions? LINK to parts. Buffer is #5. Would like to find some bullets and dies to try and reload. Some folks have used 556 cases which see like the least amount of labor to get to fit. It came with some ammo, little bit of brass, and a few mags. Anyone have any experience with one? Tips for finding parts or reloading components?  Attached File Attached File Attached File |

Do you know what the buffer is/was made of? Considering the time frame, I am going to assume leather or felt.
Gorgeous gun, by the way!!!! |

No idea. Will get it apart next week and look but doubt I'll be able to tell.

I looked around quite bit... sounds like one would need to be made.
I also posted at your thread at the "Hide". |

I have had one for decades, i love showing it to uninformed leftys, who think mag fed, semi auto intermediate caliber rifles are a modern invention. When i point out it was manufactured in 1907, the expression on their faces is priceless.
I have no issues with the buffer, but i guess one could be made easy enough, I would purchase one of those buffers made for the AK's & cut it fit, or cut one from a thick piece of leather or try to make one out of an automotive suspension bushing. |

Relevant to my interests. I’ve got a 1905 that’s got a chip in the buffer so it probably needs a new one. I also couldn’t manage to get the spring guide loose so that’s a problem too.

When I owned one, I replaced the buffer (I picked one up at Numrich when they had them) It appeared to be a composite leather - almost like a cross between cork and leather. I replaced it following a YouTube video as it wasn't real easy to do but got it done.
I'm fairly certain one could make one from a urethane rubber of similar thickness - it is going to prevent hammering of the bolt carrier - amazing its just a simple weighted carrier "blowback" gun (no locked breach). Many of these will have cracked stocks and fore-ends because someone didn't swap out the buffer and it cracked with the force. |

You could guy hard cast .355s or .357s and size them down

Once I get the buffer removed I may try and find something locally.
I was unaware you could size bullets until last week. |

Finally got it apart and it took some doing. Probably hasn't been apart on 50 years :)
The rod was not letting loose even with Kroil and heat. Screwdriver would just slip out of the groove. Stuffed some wood in the action to keep the rod out of the end of the bolt and used a big set of vice grips to turn the rod. It'll be a real chore getting it back in! Before disassembly you can see no gap where the buffer should be providing a gap to prevent metal on metal during cycling.  Attached File'Smif' tools:  Attached File Attached FileBuffer looked decent until I dug it out of there, then it came apart. Will try and find some delrin to replace it.

Thank you for posting, hopefully your measurement can help another owner.
How stiff is the buffer ? What material would be suitable , as a replacement ? I would hate to see a fine rifle banged apart from to hard of a material... and vice versa. And I don't know enough about shock absorbing ... but Sorbothane keeps coming to my mental midget mind. So I will throw this out there.... I do know, Sorbothane wants to absorb the shock "sideways" , or expand outward when compressed. Or maybe a combination of various materials... IE a softer part in the bottom of the cup , with a more durable part where it impacts. I don't know if it is "easily" cut or drilled readily https://www.sorbothane.com/technical-data/articles/what-types-of-materials-are-best-for-shock-absorption/ Sorbothane Catalog... maybe you can find something helpful. ( PDF ) https://www.sorbothane.com/wp-content/uploads/Sorbothane-SPG.pdf About the 1:50 point.... ignore the late '70s video, the company is still around.... the stuff does work at absorbing impact. And please note every video shows a wide impact area ( the flat wooden mallet face )  Sorbothane - That's Incredible1 Anyway... hopefully others with more technical knowledge can add input. |

And... maybe one of these could be made to work ( ? ) Unsure of the longevity of those.

Unsure what would be ideal for a replacment.
Guy who I got it from found what look like a buffer in the bottom of his safe and is sending it to me. Says it's 'slightly magnetic' which may be it from the info in this video:  Winchester Self Loader recoil spring reinstall. If not delrin should be fine. |

I'm thinking that an automotive "anti-sway bar end link bushing", made from either rubber or polyurethane, could be used for this buffer. The O.D. of the bushing might need to be reduced, unless you find one for a very small vehicle.

Made a crude buffer out of delrin. Took a couple hours and 3 attempts to get it all together (using the video posted above) trying different tricks and tools. Not a fun job.
Now I am having issues getting the for end on. Will work on it more another time.  Attached File Attached File Attached File Attached File |

I wonder how long a TPU printed buffer would last.

Was having issues getting the front cocking lever on due to the spring wanting to bind. Finally dawned on me to use a paperclip to hold it back.
She's together and we will see if I die tomorrow.  Attached File Attached File Attached File351 Win, 556, 300BO  Attached File |

I wouldn't personally buy one but it is fun to shoot. Put 10 rounds through it with no issues.
Recoil is pretty light probably due to the huge bolt. It's fun for sure! Rear sight is loose but the screw holding it on is tight. The front cocking rod is supposed to be able to be twisted (when compressed) to lock the bolt open but I'm not able to twist it with my fingers.  Attached File Attached File |
