There's no way anybody would load a bar to 430.  Let's look at this logically: 1plate=135lbs 2plate=225lbs 3plate=315lbs 4plate=405lbs 430 would be 4 plates, a 10, and a 2.5 one each side.  Nobody benching more than 2 plates even bothers with the 2.5 lb plates unless they're in a competition.  You just can't feel a difference between 225 and 230.
