I'm reloading my first bottleneck cartridges (.223) and I ended up with a Dillon 3-die set (FL sizer, bullet seater, and taper crimp) which I'm VERY happy with. Upon further thought, I also bought a Dillon case headspace gauge to properly adjust the sizing die. So far I've sized and primed my cases, and I also have installed the seater die and have that properly adjusted. Now comes the time to install/setup the crimp die. The Dillon set includes a taper crimp die....but I also have a brand new Lee "factory crimp" die still in the package (it was given to me some time ago). Now that I am actually at the point of reloading some .223, I need to choose one of the crimp dies. Which one is better? Opinions?
