The portion of the 7 BR die that represents the shoulder of the BR case is at the proper location and of a suitable taper to crimp the case mouth of the 45 ACP shot shell. Plus the BR die is of appropriate diameter to support and align the case for crimping. Anyway, that's what I do. It won't help you if you don't happen to have a 7 BR die set.
