Bullseye Shot and Readied Actions

[Serum]

Can you use Bullseye Shot as a move action before you ready an action to make a ranged attack?

Bullseye Shot (ISG):

Quote:

Prerequisite(s): Point-Blank Shot, Precise Shot, base attack bonus +5.

Benefit(s): You can spend a move action to steady your shot. When you do, you gain a +4 bonus on your next ranged attack roll before the end of your turn.

Does my turn end before my readied action triggers (generally on someone else's turn)?

If I state that I'm making a ranged attack with the readied action, is that enough to satisfy the conditions to allow the +4 bonus?

No, when you ready an action, it ends your turn. In order for bullseye shot to apply to readied actions, it would need to say you gain a bonus on your next ranged attack before the beginning of your next turn.
