One thing I was going to mention above that I forgot was the Lee Factory Crimp die is sized for normal jacketed bullet diameters. All swaged, plated and cast bullets are normally sized .001" over a jacketed bullet to get a better bore seal. If you run a LEE FCD it will size the bullets inside the case down to jacketed size and that can be bad for accuracy, cause leading, etc. For example if you load a .356 coated or plated bullet and and crimp with a Lee FCD the bullet will be sized to .355" inside the case. This may or may not be a bad thing in your gun but it usually isn't good.
I read about this and I’m going with just a straight taper die.
