guy baxendale Posted November 24, 2023 Report Share Posted November 24, 2023 Generally they are made to the mould of the chamber of the gun in particular. Quote Link to comment Share on other sites More sharing options...
Pushandpull Posted November 24, 2023 Report Share Posted November 24, 2023 Custom cases are indeed made today for the individual gun - I believe a sulphur cast can be used. However, the brass "Perfect" cases were obviously made to a standard dimension. They are surprisingly thin, allowing them to be reloaded by a 45 degree hand crimp a number of times. Plus of course admitting a suitable wad column. I have been told that there are specific brass mixtures which work best. I used to have a number of these cases and unfired cartridges in big bores but I regret they are long gone. Someone out there must have one or two. Would a paper case not be close enough to copy the dimensions ? Quote Link to comment Share on other sites More sharing options...
derbyduck Posted November 24, 2023 Report Share Posted November 24, 2023 I use 1 inch brass very pistol cases ,I bought a box of 25 for £10 and resized the primer pockets to take 209 primers , they are a parallel case . Quote Link to comment Share on other sites More sharing options...
Andy H Posted November 24, 2023 Report Share Posted November 24, 2023 Go onto this C I P page and it will give you the cartridge drawings and the chamber size drawings for 3-1/4" and 4" 4 bore . https://bobp.cip-bobp.org/en/tdcc_public?page=1&cartridge_type_id=7 Quote Link to comment Share on other sites More sharing options...
Pushandpull Posted November 24, 2023 Report Share Posted November 24, 2023 Well live and learn ! Never heard of 4/82 (3 1/4") four bore. Another route to consider might be to turn up brass cartridge heads (much easier) and then attach a tube made from one or two turns of card or "cartridge paper". this is the method widely used for punt guns such as those originally chambered for the Eley 1 1/2" cartridge case. An easy route but the cases do not survive beyond one firing. However, how many shots does one fire at one time with a four ? I seem to remember (going off-topic here) that Al Myers had plastic cases made in this calibre at one time. There may be some out there somewhere.

How about using the heads and a 3D printer 🤔 Quote Link to comment Share on other sites More sharing options...
