yeah...thats right ..another controversy

I am about to have my .333 Jeffery rifle built
and reading John Taylors book "african catridges and rifles".. he rates this particular cartridge high. 11 kills, 11 shots and 11 elephants.
Both cartridges shoots 300grain bullets at moderate 2200 Ft/sec I instanly fell in love with this beut.

One can slight see the metfordrifled barrel at the top which is made by Arthur Smith in england. The barrel contour is taken from David Littles(Kynochs) original .333 jeffery.
I believe these loooong bullets have some kind of potential.

very nice I am currently working up some loads in my 9.3x62 with 320gr Woodleighs I am hoping at getting around 2200fps I am going to have to test some over the Chrony when I get a chance

If you're braining elephants then a 333 with solids ought to be just the ticket. You gotta love a cartridge where nearly half its length is bullet!

Indeed. That is a sexy cartridge. With the moderate velocity, the rifle should be much fun to shoot.

Hi,
Congratulations Jens!
I am vaiting getting my janssen double back from the gunsmith.
the long winter is over and it's time to develop nice loads for the 300 grains bullets in my "Jeffery Triple Three Flanged"

.

ALF,
Thank you for the information. It's always interesting to take part of your knowledge!

Did you know that Denis Finch Hatton (i think it was) claimed according to Bror Blixens book "Letters from Africa" to have shoot down a German double decker with his H&H Royal .450/.500 N. E. Double rifle that was harassing the British trenches in the Flanders.

He gave it "A right and a left" and down it went...

ALF,,,, that triple 3 flanged looks alot like the 33 Winchester,,would they be close in performance?

The Triple Three fires a 300 grains bullet at 2150 fps (SD .386 )

.33 Winchester / dia = .338" / 200 gr / Sec Den = .250 / 2200 fps / 2150 ft lb


.333 Jeffery Flanged / dia = .333" / 250 gr / Sec Den = .322 / 2400 fps / 3198 ft lb (28" barrel)
.333 Jeffery Flanged / dia = .333" / 300 gr / Sec Den = .386 / 2150 fps / 3080 ft lb (28" barrel)


.333 Jeffery Rimless / dia = .333" / 250 gr / Sec Den = .322 / 2500 fps / 3470 ft lb (28" barrel)
.333 Jeffery Rimless / dia = .333" / 300 gr / Sec Den = .386 / 2200 fps / 3225 ft lb (28" barrel)

You should be more concerned about the brass situation.....Bertram brass is no good ....and you will have to expect a loooooooong waiting period for Dieter Horneber to make up the best brass in the world ...yeah....thats right, I have just recieved 80 pieces of the Horneberbrass
which will cost you(living overhere) about
$6 a piece ....but what the heck??...when going for this caliber everthing becomes diffecult and expensive, but that`s the fun part

Ken Stewart, Pietersburg South Africa makes also bullets. Hi´s "Hi Performers" soft nosed bullets has a thicker jacket than the Woodleigh's. I have ordered some 200 pieces of 300 grains bullets

What is largely unknown about this cartridge is that the British forces used it as an anti material gun in the first world war. Mauser against Mauser literally.

German snipers would shoot from ported iron ?metal shields and a 303 could not penetrate the metal of the shield.

The 333 however using those long typical FMJ's could take Jerry from behind his shield.

I read about that in Hesketh-Pritchard's book. Seems he talked his commander in to letting him tour London gunmakers, who were eager to help in the war effort, in his search for something that would shoot through the shields. He got scoped rifles and ammo from Rigby, Jeffery and a couple of others, and went to war with the finest English rifles of the day.

Nice work if you can get it.

THANK YOU THANK YOU THANK YOU

jens,

Thanks for posting this topic. The 333 Jeffery sounds like a very interesting round, when was it developed? What loading will you be using, 250 grain or 300 grain bullet? What sources are there for reloading data?

I am interested in knowing more about the rifle you are having built, around the 333 Jeffery, and would appreciate you sharing the specifications for your rifle.

Thank you!

i concur with the 333 jeffrey, its a great round and it should have been used more in the world. Taylor didn`t like the 250 grs because it expanded to fast and wasn`t reliable, he preferred the 300 grs wich had a tendency to penetrate very deeply and it was a very effeicient cartridge
