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.

Cherish our flag, honor it, defend what it stands for or get the hell out. Our Freedoms are not free, they've been paid for many times over by heros in uniform. Far better men than I, died that we could be FREE.
