SFM 40-60-260 Winchester


#1

Here is a box (heavy paper) labeled as 40-60-260 Winchester. It came with the single round pictured. Bases on bullet weight (260 gr) and case length (2.12") it is actually a 40-60 Marlin or 40-65 Winchester.

Were the three cartridges interchangeable? Any idea of it’s age?

Thanks
Paul

Can’t find my copy of the SFM drawing for this cartridge but I think it should exist. It is not shown in the SFM 1900 catalog but it does in the 1912 edition.

This is the same case type as the .40-60-260 Marlin and .40-65-260 Winchester.

The “.40-60-260 Winchester” is in fact a mixed designation only adopted by SFM. I was never used by Marlin or Winchester.

Rimfire & Fede–The .40-60 Marlin and the .40-60 Winchester are not the same and will not interchange. The Marlin (and the .40-60 C.L.M.R.) uses a 2 1/10 inch case with a 260gr. bullet. The .40-60 Winchester has a 1 7/8 inch case and a 210gr. bullet.

The .40-60 Marlin and the .40-[color=#0000FF]65[/color] Winchester are interchangeable and both use the 260gr. bullet.

Ron,

 I agree with you but this ".40-60-260 Winchester" by SFM has a 2.1" case so it's not a .40-60 Winchester.

#5

Fede–Strange designation with the 2.1 inch case. I wonder if S.F.M. made the true .40-60 Winchester with the 1 7/8 inch case as well. If so, what did they call that?


#6

Ron,

  This is one of those cases in which an almost evident catalog mistake turns out to be true. I'm not aware of a .40-60 Winchester (1 7/8" case) produced by SFM.

Thanks, I thought the 40-60 Marlin and 40-65 Winchester were basically the same case but wasn’t sure if the shorter 40-60 Winchester was interchangeable.

Thanks again,
Paul

Paul,

Great box and cartridge!

For the sake of comparison, here is a .40-60 WCF on the left next to a .40-60 Marlin.


While the head diameters are both near .500", the rim of the .40-60 WCF here is .618" vs. the .40-60 Marlin’s .600".

I pulled my specimens of the .40-60 Marlin and the .40-65 Winchester and noted that the .40-65 OA length was less than the .40-60 (tho both have the same case length, about 2.1 in). Is length variation–the Marlin version longer than the Winchester–a generally consistent one? Jack
