.41 Swiss

[Battis]

I pulled the bullet and powder from a very old .41 Swiss cartridge. The bullet is 300 gr, hollow base, and might have been paper patched. It held approx. 14 grs of a very fine powder.
Is there any way to ID the powder or its modern "family" based on its look, size, etc?

A full box of UMC 41 Swiss ammunition is worth about $150. I wouldn't worry about the powder and not pull any bullets

I want to replicate the load with a slightly heavier bullet and I was wondering what modern powder is equivalent.

Yeah, I read that link. I'm trying to figure out what type of powder was used that only required 14 grs.

Joe (smokem joe, now deceased) used 12 gr. Of Unique. As usual, start low and work up.

I have real good luck with the Lee 310 grain bullet and 18 grains of 2400. I have tried it with GC no GC, lubed or LLO, large rifle and large pistol primes they all seem to shoot just as well.

Philip B. Sharpe's book "Complete Guide To Handloading" shows many comparison photos of obsolete and current powders[1949],also gives detailed descriptions of the powder's history and popular applications. Not having seen your powder, my guess would be SR#80, discontinued in 1939, or maybe DuPont#1204, disc.1935 and later replaced with IMR4227, or it could be a powder that was never offered to the public. Anyone interested in old cartridges and reloading history should get this book
