In the spirit of scientic inquiry, my two colleagues are going go help me convert some loose vintage 351 ammo into brass. An important part of the process will be testing the Caldwell Brass Trap. 

We've got Skeet to shoot and at least two Model 50 shotguns and the aforesaid Model 25 to pattern. 

And a 1931 Savage 99F .303 to sight in. 

All before 11AM when Satan finds Hell is too cool for him and rents space in North Texas.

Bert,
That rifle shows the perfect blending of form and function, the melding of art and engineering.  Can you tell me what it is chambered for? (and when you will be dropping it by my house.)

The SSSR in the pictures I posted is s/n 75874 and it is a 32-40.

The majority of the SSSRs were chambered for the 32-40 or 38-55, but they were made in small numbers in numerous other cartridges.  The SSSR was Winchester's first dedicated Target rifle.  They were available as early as 1886 (the Schuetzen Rifle did not make its appearance until March 1896.   

Unfortunately, I do not own it , nor would I ever just drop it off at your house!

This is a typical SSSR

Gentlemen,  
The question I raised was about the material used to make the buffer washer, not the buffer.
Henwood described the buffer itself as being made of some Vulcanized fibrous material. I believe a  popular modern material used to make them is HDPE - High Density Polyethylene -  the cloudy-looking, flexible plastic that milk jugs are made from.
The buffer washer i unwrapped I expected to be metallic but it isn't. I got it twenty years ago, sealed in plastic film, from GPC.  I'm pretty sure it was a Winchester factory part.
  

Bill,

Or Nylon!

In the words of T. C. Johnson in his June 29, 1903 patent application he described the buffer as "compressed fiber or other equivalent material". Patent 768665 was issued August 30, 1904. Rather vague but consistent with the above photo.

That makes sense Mike, as it does look like compressed fiber, and with Adam's suggestion, like a pressed Masonite, or some sort of fiber, as you've explained from the patent information, I would guess possibly a better upgraded material of today could be used and fasioned to get more use and life out of it! IMO!

It would be nice to find specifications indicating what this was made of.

Are you sure this is original to the rifle?
