Supporting a 28 Bore case during roll crimping

I do like unusual request and this one is worth taking a closer look at.

A customer reloads his own 28 bore cartridges and asked if we could build a holder that supports the case during the roll crimping operation, so here is the prototype.

The holder is machined from soft metal (6082 Aluminium) sized to the cartridge case with the case head just standing proud. The cut out is to enable the case to be held without rotating during the operation. The prototype pictured seems to tick the box so I will machine a small handful in case i ever get asked again.

It was an interesting project and this seems like a simple and elegant solution arrived upon over a cup of coffee 🙂
