Doubling Hawkins's gun count also means doubling the ammunition carried if the allowance per gun stays the same. The discussion uses roughly 400 rounds per gun to show why the extra weapons increase displacement beyond their mounting weight. A barrel life of about 650 rounds is then cited as a separate constraint on sustained firing. Both figures belong to the argument over the proposed Super Hawkins and its support requirements.

Super Hawkins needs ammunition as well as additional guns
A fourteen-gun Hawkins derivative also enlarges its ammunition load and faces the barrel-life limit cited in the discussion.
