Any good anagrams for chamber of a piece of ordnance?

The end of the bore modified to receive the charge of powder. In mortars, howitzers, and shell-guns, they are of smaller diameter than the bore, for the charges being comparatively small, more effect is thus expected. The gomer chamber (which see) is generally adopted in our service. In rifled guns the powder-chamber is not rifled; it and the bullet-chamber differ in other minute respects from the rest of the bore. Patereroes for festive occasions are sometimes called chambers; as the small mortars, formerly used for firing salutes in the parks, termed also pint-pots from their shape and handles.
