    I use a Hornady taper crimp die for .45 ACP. Not really sure how much crimp I use but I guess I could measure it later tonight if you'd like

    All you need to do is remove the bell from the case mouth unless you'll be shooting your reloads from a revolver, ie. S&W 25 or 625, then a roll crimp would be useful.

    ALL semiauto pistol rounds should have a light taper crimp, always. Despite what some guys will say about there ammo running fine w/o, it will run better with a taper crimp. They will chamber better, & accuracy often improves from consistant bullet pull.

    +1 to what Fred says.

    I use a taper crimp of 0.005", maximum, measured at the case mouth. A crimp of 0.002" - 0.003" is enough. Too much crimp will damage the bullet and too little can result in feeding problems. I use the barrel from the pistol I'm reloading for as a gauge. The finished round should drop easily into the chamber with a definite "thunk" sound when it bottoms out. The case head should be flush with the end of the barrel hood.

    I use a Dillon taper crimp die for my .45's. I crimp them to .469, approximately .0015 per side. Visually, it's not much!

    +1, Just enough to show it is crimped.

    I do not understand what you mean by this question: "do you guy use a lite on your .45 acp?"

    I use a small taper crimp as well on all autoloading ammo.

    Bingo... I ran my loads for through the XD without a crimp up until I got my Sig, which needed crimped loads to not FTF. Its really a good idea to taper crimp em all.

    I taper crimp .45acp to .469 +/- .001" at the case mouth. No need to roll crimp these for revolver unless you're using bullets heavier than 230gr.

    Yup. Taper crimping is the way to go on auto ammo, period.

    If you don't crimp or you roll crimp you run the risk of having FTF issues either way.

    Taper crimp them. I shoot for .470
