Dear all,

just found this thread on bore gun projectiles- very interesting as I have a Martini actioned Francotte 24 bore. A chamber cast revealed a case lenght of about 40mm long- bore is 0.608/0.626 as far as I can measure this accurately - 7 grooves you know. A shortened 24 magtech case will not chamber (rim thickness+ diameter of the case just in front of the rim).
I have some questions to you, Lancaster:
- are there some moulds available for these projectiles
-which reloading dies to use for these short cases????
-Could you furnish me the exact dimensions of the RWS 'cathead' projectile?
Do you have reloading data for these short 24ga cartridges (smokeless powder or black)

At first I thought I had bought a 577 snider but this was way to small for the bore size. Dimensionally these short 24ga cases strongly resemble the 58 berdan cartridge but the bore size of the berdan is smaller

Best regards,
Benny




with a 15,44mm/15,90mm diameter barrel there is nothing that could fit. even the biggest in this group the 15,24x41R Russian Krnka have only a 15,24mm. bullet.

in a Martini action I remember also a .577 Snider cadet with a 40 mm long case but also way to small. the RWS cats head bullet in 24 ga. had a 15,70mm/15,80mm diameter( for the stop ring)



notice that there a two different bullets for Papphülsen (paper shells ) and Messinghülsen (brass)
and the stop ring have allways the same diameter: 15,80 but the bullet under the stop ring is smaller for paper shells
18,70mm is the length of the bullet, 33,3 gramm is the weight



I measure 24 ga Magtech brass here with 15,77mm inside and 16,29mm outside so it would be possible to made a cats head type bullet with a 15,75mm to 15,90 mm diameter.
15,90mm would be the ring laying against the case mouth.
a 15,90 mm roundball is another possibility, of course. I dont know anyone making such moulds but if you wish having a very good craftsman here who could make it for you. best will be if you have an old RCBS/Lyman steel mould you dont need anymore so he had only to change it inside.
did you have made a chamber cast now? you will find that Magtech brass will stand black powder loads very well. in my Husqvarna 17a in 28ga I shoot 40mm long Magtech brass loaded with 90 grains FFG and a 480 grains Lee Minie bullet slug to .600 and its not necessary to resize the case.
the original brass is also to thick over the rim so I lathe turned this and resize the case to a smaller diameter with a home made die.
BTW, I have a 24 ga. hammer double gun by Victor Collette in Liege the Magtech brass is also a little bit to thick over the rim when FIOCCHI 24 ga plastic shell's fit without problems. fortunately its not so much I cant turn the brass down on the lathe again. it seems the chamber's for gun were smaller in the old days.
so if you dont find anyone to change your brass for the martini please dont hesitate to ask, we are EU neighbours but I need a chamber cast then.
without seeing the proof on you rifle I would suggest to start with black powder only and the cats head bullet or a roundball can set by hand.

I recommand CH4D for a die set

please make pics of the whole rifle and any details and post
