Cordite

I have in hand a 1951 item about a .50 cal. rifle whose charge was 90 grains Cordite, M.E. 6180 (Whatever M.E. is). I wasn't aware Cordite was ever offered to handloaders. Comments?

M.E. probably stands for Muzzle Energy. Unless these were factory loads, the Cordite was likely sourced from broken down military munitions. 6180 ft-lb would be about in range for a 50 caliber smokeless load. I wouldn't want to try shooting it myself.

I omitted the best part- the custom rifle involved had an 18-1/2" barrel!

That would be about a heavy load for a 500 Nitro Express with a 570 grain bullet but less than a 505 Gibbs with a lighter bullet. Unless that 18 1/2 inch barrel is at least 1 1/2 inches in diameter, that means ouch!

Yeah, the rifle pictured didn't have a bull barrel. It appeared in a Buehler ad in the American Rifleman in 1951. The ad gave me the distinct impression Cordite was available to handloaders. Since no one recalls that, looks like it wasn't.

When I was a Yonker I remember quite a few of the men around using the term 'cordite' for a whole range of smokeless propellants. Guys who had been around artillery during the war, for instance. It spilled over into shotgun shells and probably the powder in their beloved .30-30s and '06s too.

Cordite was originally a British rifle powder that was like noodles.

I have never figured out why the Poms insisted on staying with cordite  (or even beginning with it) as long as they did. The Europeans already had decent smokeless powders figured out.
It needs to be pretty fresh to behave totally as claimed, and it's very temperature sensitive to the point of wild instability.
They sure did blow up a lot of rifles with it in the beginning, especially sporting 303s.

If I remember correctly, they filled the cases with the noodles before forming the neck to get them in the case.

I was involved in marksmanship training of some State Guard people after Iraq. They fired liberated Iraqi .303 ammo, clean and post WWII. Lotta click-bangs and duds. Propellant was cordite, exactly as in Schutzenbob's post, with a paper separator under the bullet. So, don't believe cordite is no more. Never detected the famous cordite smell, though. Another myth, I guess. Buehler's intent was to demonstrate the ruggedness of his scope mounts.

Condor, I suspect that the supposed 'cordite smell' was also a generalization in the same vein as the blanket naming of any propellant as cordite by the old folks. Same as us calling so many brands, and types of jeans by the omnibus moniker of 'Levis'. Just how we go about things, ain't it?

Sure is. I have read numbers of authors of everything from detective stories to dramatizations of wars and revolutions that mentioned that smell. But, it's not entirely gone. Iraq was still using it in the '50s or '60s. I'll hunt up those rounds I saved and relate the mfr. date sometime.

Into the early '70s I shot along with an ol' pal that had a mail-ordered (from a magazine ad) so-called Jungle carbine. An Enfield, it was in .303 British and he had the remains of a couple of cases of ammo from the same source.  I am about ninety nine percent sure it'd been loaded with cordite and probably stored in the desert of Africa or somewhere for a while. It shot about as well as we did- eraticaly for us, and at least so-so for it. Sometimes I'd hit a beer can at 50-100 yards by the time I emptied the magazine.  Roll Eyes Probably more the lousy trigger and the idiot shooters than the cordite-loaded rounds. Never picked up a single case.

The problem is Cordite does smell different than most other powders. Much like Eley .22 priming compound, shot shells and Blackpowder are also different. I think it's mostly to be clever and sound like you know what you are talking about.

Odd that you should mention it. In 1963 I [my mom] bought a jungle carbine from Kauffman's military surplus in N.Y. city, still in cosmolene for $30. I chose it over the Springfields and Mausers because it looked cool. With it came 100 rounds of 303 ammo and being kids we pulled some of the bullets with pliers only to find spaghetti instead of powder. Naturally we chewed on some and found that we could make fuses for some of our  nefarious devices with it. Don't remember any problem with the ammo though. Still have all my fingers after stuffing empty co2 cartridges with it and managed to stay off of the terrorist watch list so things worked out pretty well.

Sounds like Buehler was just quoiting from the proof marks on the barrel. 
In the heyday of the 500 Nitro Express a rifle proofed in Britain would have the proof load marked conspicuously on the barrel as "80 Cordite 570 Max". The 505 Gibbs would have it marked as "90 Cordite 525 Max". The Gibbs would have 6,166 ft pounds of energy. Looks like it was a 505 rifle and if it was a bolt action (the 505 Gibbs was rimless) it could have had a short barrel to keep the OAL short to keep the barrel from hanging up in the bush. You don't want a long barrel hanging up on the vegetation when the wounded lion is coming at you.

"The smell of Cordite" is a hackneyed phrase that  "journalists" love to use. They have no clue.
