However cannon barrel wearing was not an absent factor, specially with early ammunition, such as stone balls, used in bombards (pedreiros). Despite those being wrapped or bagged, their rough texture damaged barrel bores in that, after a determined number of shots (they 100), cannons were due to reenter arsenals for remelting.
