I have both, and they are drilled similarly.  The Bedlam is drilled 5" x 4-1/2", 2" pin buffer, above and right of ring, and the 505A is drilled 5-1/4" x 4-1/2", 2" pin buffer, with a weight hole next to the thumb.  The Bedlam is at box finish, and the 505A is 800 grit + polish.  Both are angular at the breakpoint, but the Bedlam is much more angular.
