I have two early 7,5 Swissicon cartridges in my collection, one is the GP 90/03 with the patched lead, steel capped round nose bullet (211 grs) and the other is the GP 90/23 loaded with the FMJ round nose bullet.

On the GP 90/23 FMJ round nose thereAttachment 97951Attachment 97952 is a wax ? seal around the case mouth and rear section of the bullet as noted in my photo.

My question, what is the purpose of this wax seal ? is it removed before you fire the cartridge or do you fire the cartridge with the wax seal ?
