I need someone good with physics to run through for me how to achieve, basically bullet code where the bullet can travel towards an object at a certain angle, and then bounce off that object, with a certain degree of deviation, %-wise.

One will need to calculate the normal (perpendicular) angle from the surface of reflection.
Then, the angle of reflection of the bullet will be the same angle it came in at from the normal.

EDIT:

The deviation will come from a percent of error, such as a 1% deviation: the angle reflected x 0.01

How would one calculate that? The reflection angle? Is there an algorithm? Or is it just same velocity, reverse direction, account for error?

It is exactly that, just the same velocity, reverse direction, and then create a random number/percent to deviate. Remember, the angle is flipped over the normal.
