Using: take, hold, or deploy (something) as a means of accomplishing a purpose or achieving a result; employ.
When using a ranged weapon without the volley trait, you gain a +2 circumstance bonus to damage rolls on attacks made within the weapon’s first range increment.
When holding a ranged weapon without the volley trait, you gain a +2 circumstance bonus to damage rolls on attacks made within the weapon’s first range increment.
While it may be common sense that the word using in terms of gameplay for this example is to shoot a weapon. There have been situations in which wordings have been debated much more.
