Plus 1 on Geewilliker's #5 post...excessive roll crimp actually results in looser bullet/case neck tension...a taper crimp works well for me and doesn't actually require a dedicated taper crimp die...you can use either a .45 LC or ACP sizing die, with the decapping rod removed, to taper the case mouth as necessary to prevent bullet movement in recoil.

Our Flag does not fly because the wind blows against it,
It proudly waves because a soldier's dying breath blows upon it.
