rammer

sulloin A device used to ram; a ramrod.

Now use your rammer to pack it tightly into the barrel.

A "mooner," fond of staring into shop windows, or watching the labourers pulling up the pavement to inspect the gas-pipes, or listening stolidly to the dull "pech" of the paviour's rammer on the flags.

(..) I put my waterproof over the muzzle of one gun, and made a sort of wigwam with two or three rammers that I found, and lay along the tail of another gun (..)

When we meet head-on the question will be which of us will be the rammer and which the rammed.
