.303 id

Hi all,
Many thanks for the previous help on my dummies!
I need again some specialists about those 6 rounds:

#1: No H/S, could it be Canada made? (“Canada” writen on it when I got it)
#2: .303
#3: B.P C-50
#4: No H/S (“line thrower H?Z, proof Kynoch Birmingham” writen on it)
#5: 303 BRIT, soft point
#6: SUPER 303, soft point


#3 has this “je ne sais pas” Italian look

  1. IIRC was made by CIL in the 70s for house brands of retailers.

Vlad was on the right track for #3, Pirotecnico Esercito Capua, Capua, Italy; 1950.

No1 - More likely an early “CAC” round, Both Australia and New Zealand produced MkII rounds with no headstamp, copper primers and no primer crimp.


  1. is interesting appears to be a MkII or VI but lacks stab crimps.
    I have examined no hs MkII or VI .303" ammo in Canada.

#6 Super Cartridge Co, Australia.

No 3. If labelled correctly, this would be for proving of the actual line thrower, used by the Navy. The cartridge for propelling the line would be a H Mk. 2, and have a completely blackened case, and been produced after WW2, most likely.

There are 3 stab crimps on #1; I’ll pull out the bullet to ckeck powder and bullet weight.
What does mean IIRC and CIL?


IIRC = If I Recall Correctly

Hi Philippe,

#2 was made by PMP in South Africa as is found in several loadings, both sporting and military.
#4 is indeed a proof loading of the H Mk 2 line thrower cartridge made by Kynoch. It is loaded with Cordite and should have a non-magnetic GM jacket with a plain cannelure.
#5 was made by IVI of Canada in 1981. It is loaded with a 150 gr PSP bullet.



No.4 Proof line throwing round ?? can anyone give me any reference details on this round or any drawings, I would like to understand more about this round. I have looked through my books and I don’t have any info on them. This might be a silly question but why would a Line throwing Proof round have a bullet in it, is it to aid in building up pressure for the proof test.

many thanks



I don’t have any documentation to support the theory, however, I would think the round with the bullet would be used as a barrel proof. This has nothing to do with the proof of the cartridge itself.

Rich, this Line Throwing Proof round is genuine although I am surprised to see one without a headstamp. They are obviously scarce because, as you say, even TonyE makes no mention of this load in his books. I actually saw a specimen at Bisley a couple of years ago with a ‘HMk 2’ headstamp but thought it must be a fake. I went off to find Tony to ask his opinion and when we returned it had gone.

Maybe you speak about the second one Jim. I found it in Netherlands 2 years ago and got the first one from someone in France who bought a complete collection.
Here is also what is writen on the first one when I got it.

Both of them are non magnetic.
#1: 396.4 gn
#2: 396.3 gn

Jim I am not questioning that it is what people are saying it is I am asking if anyone has any info because I cant find anything about them and I like to Know :-)


Rich, this loading is mentioned in two of the catalogues/identification guides published by Conjay Arms between 1970 and 1975. One of its descriptions says: “This cartridge was loaded as a ball round in order to proof the case. This and the Naval Contract H2 are the only 303 Line Thrower cartridges ever produced by Kynoch”. This is one of a large list of Kynoch’s proof loads that are mentioned in these publications, which in many cases are, to my knowledge, the only available reference.



I remember Tony Edwards telling me that there are also plain brass cases headstamped “K 70 H. 2.” and loaded with ball bullets. These were apparently ball ammunition loaded by Kynoch on contract for Nigeria.
