[QUOTE="Buzzdraw, post: 1749877, member: 385"] In .45 ACP, it used to be common to find roll crimp dies, but this is no longer the norm. Taper crimp, to .469" +/- .0005 works well for feeding and accuracy. The bullet is held in place, in a .45 ACP, by more than just the crimp, or at least it is in a more optimal world. GI factory ammo sometimes has the black asphalt-like sticky stuff, in addition (sometimes) to having a cannelure rolled into the case at the base of the bullet. When reloading .45 ACP, it is a good idea to use a sizing die that will take the diameter of the case down to the small end of spec's. In this instance, you can actually see the bullet body outside the loaded round. Additionally the base of the bullet is held better in place by the diameter of the case wall. [/QUOTE]
