As long as total final reduction in caliber was not more than .009 for a jacketed bullet, concentricity should be sufficiently preserved. If the bullet is not bonded, it is possible the jacket may spring back more than the core and cause the core to separate from the jacket. In Swift A-Frames for example, the front section of the bullet is bonded, but the rear section is not. This can be easily remedied by using a cannelure tool and adding a cannelure to bond the jacket and core.
