Full attack with blowout shot deed

[willuwontu]

If you load the blowout shot can you full attack that same turn?

Alternatively can you full attack the next turn if you don't fire in between same turn?

Blowout Shot Deed (Grit)

Prerequisite(s): Craft (alchemy) 3 ranks, grit class feature or Amateur Gunslinger feat.
Benefit(s): Spend 1 grit point to retrieve a specially prepared dose of black powder from your person. The next time you use the firearm you’ve loaded with this special black powder, the concussive blast knocks you back 5 feet from the direction at which you were aiming. If there is no available space behind you, you brace yourself against the obstacle and do not move from your square. Any creatures within the first range increment of the firearm struck by this attack take damage as normal and must succeed at a Reflex save (DC = 10 + 1/2 your gunslinger level + your Int modifier) or be pushed back 10 feet. Creatures within two range increments are pushed back 5 feet, while creatures farther away than this are unaffected by the concussive blast.

Edit: Also can you do it multiple times in a full attack if you spend grit each attack?

I see nothing preventing any of these options.

Aye, I just find the lack of an action cost associated with it as weird.

The required action is loading the gun, you spend grit to boost the ammo as you load it.

Well, my pistolero just finally decided what to use for his Signature Deed...!
