It is meant for the Martini-Henry rifle and can be used with either paper patched or plain lead bullets. If the larger 0.468″ paper-patched bullets are used, a larger expander plug may be needed to avoid damaging the paper. Most commercial die sets seem set up for 0.458″ bullets. If needed we can also supply paper patched bullets for this cartridge. This brass is packaged in lots of 20. Shipping weight is 435 g/20 cases.
