Make sure that the transition to the animation is instant; and have the animation trigger the line after you have the bullet shoot. To make sure an animation transition is instant: -select the transition arrow in the Animator Window; -in the top right of the inspector there is an icon with a down-arrow next to 3 horizontal lines, click it; -select Debug from the list that drops down (you can set it back to normal after); -in 'Transition Duration', change the field to zero. Also check to see if the animation it's transitioning FROM doesn't have an exit time.
