A method of controlling the dimensions of a "finished" can for a shaped three piece can comprises forming a fully circumferential feature such as a bead (21) on the shaped cylinder (20) which comprises the side wall of the can body blank. The can body blank is subjected to an axial load which causes the bead to deform in a controlled manner in order to adjust the height (H2) of the shaped can body blank. The height of the blank (H3) is thus made compatible with standard machinery used to produce the finished can (23) and the finished shaped can is of the same level of dimensional quality as cylindrical cans made using the same standard machinery. <IMAGE>
