First, a "Dry Fire" is firing the bow without any arrow so no you wouldn't be dry firing. Second, bigcountry's right, 2 grains is negligable, you wouldn't notice it.
Im not an expert up I'm pretty sure if your arrow is to light for our poundage, it can have the same effects of a dry fire.
True, but 2 grains under the 5 gpp limit will never hurt any bow. To cause dryfire type damage to a bow you have to be shooting an extremely light arrow.
