577/450 Kynoch box


#1

After Guy’s question about the Kynoch box colours on the “Kynoch date code” thread, I looked through my Kynoch boxes. For some reason, this one amused me so I thought I would share.

Is it just me, or does it really matter that “these cartridges are fitted with Non-rusting caps” given that they are loaded with Black Powder?

Cheers,

Possible connection: Green for blackpowder and yellow for smokeless? I have never seen a box of Kynoch smokeless blanks. My .450 Blanks are blackpowder, and 3 modern Kynoch Nitro Express boxes I have are red and yellow.

After looking at the Kynoch boxes in my collection the colours seem to indicate what powder was loaded.

green/red=Black Powder
yellow/red=Cordite
blue/red=Nitro for Black

Maybe someone else can confirm this?

Seems the most logical explanation. Can anyone such as John P-C confirm this?

See my post on the .450 blank thread confirming the colour codes.It is detailed on Page 32 of the 1950’s spiral bound Kynoch catatlogue.

Yes it would matter, it the caps were non-rusting as the older cap salts were another source of rust.

I shoot blackpowder regularly and have no problems with rust, cleaning is necessary but simple. However, the residues from some primers, irrespective of propellant type, are very corrosive. Years ago I fired some WRA 1943 .303 rounds which turned out to be AGRESSIVELY corrosive. As you walked back from the firing point you could just about hear your rifle rusting. I cleaned that rifle every day for a week before I stopped the rusting. Never again will I shoot U.S. wartime ammo, I inerted the rest and made dummies for clip fillers.

Well, learn something new everyday. I shoot a lot of black powder, in both muzzle loaders and cartridge arms, mostly 577/450 MH and 577 Snider. I have to clean quickly or the black powder causes rust. If I had to guess it might be the climate, where I live it is very hot and very humid. However, a pot of boiling water down the bore seems to take care of everything so I have never had a problem with black powder or corrosive primers. BTW, I think the POF primers are worse than the WW2 WRA.
