1)I know the recommended crimp is .469-.470 for .45 ACP should you use a lighter crimp when using plated bullets such as berrys, zero and montana gold?

Any comments as to which of the three is better would be appreciated (berrys, zero and montana gold)

I haven't used any but the Zero in those brands and they worked fine in a Sig220 and SW645 and 1911CC.....I use a taper crimp on auto shells and don't have a "set back" or feeding problem with the taper set for a firm pull....I haven't ever measured the amount of crimp...just check for feeding reliability and powder burning well and results on the paper.....I'm not sure if this is what you are asking but on auto cartridges with uniform shell length and good taper crimp type dies I've never had a problem with correct sized bullets...cast.few coated and jacketed.......SORRY ABOUT THE BLANK POST DON"T KNOW WHAT HAPPENED...good luck and good shooting!!!

Thanks Bigdaddy I think I am going to order a case of zeros and try them out.

I use the approximately the same amount of taper for plated, lead or jacketed bullets in 45 ACP. I don't like to constantly fiddle with the crimping die or the expander die. I set them and leave them alone.

I use a Dillon Square Deal for loading the 45 acp. From past experience I've learned to take the powder thru/expander and chuck it up in a power drill. I set the expander to turning then begin polishing with progressively finer grit emory cloth. The flaring part of the expander is not affected just the part that goes down into the case.
This gives a much smoother finish and reduces the diameter that the case is expanded to slightly.
I get a much tighter grip between the case and the bullet and with using the taper crimp die I get good powder burn and no bullet set back.
