[QUOTE="Bullet bumper, post: 688977, member: 17844"] That is not quite accurate. Even though a jacketed bullet is swaged under quite high pressure that has nothing to do with the actual yield strength of a gilding metal jacket and the lead core under it . Gilding metal is soft and weak and lead is even softer . Totally different issues. High neck tensions and bullet crimping can all damage the jacket and core of a bullet , Most times not to any great detriment to accuracy but if a bullet is seated out of centre alignment under high neck tension it is possible to ripple the jacket or squish the bullet out of central axis a slight amount . THin jackets are more susceptable . In most cases with the average neck tension that we use and with good chamfering of the case neck , this would not happen but in extreme cases it can and does happen . [/QUOTE]
