I use a Dillon 1050 and a 650. The 1050 I use for 223 and 223AI rifle and all the pistol ammo. I have no problem getting ammo that groups in the .2's out of my 223s. The 650 I use for 308,300WM, 300RUM, and 375 H&H and am able to get better than 1/2 moa ammo. So, I don't see that the accuracy of ammo assembled with the Dillons is sup par. I also use an RCBS rockchucker when I load small lots to do load developement. After I find the load quantity loading is done on the Dillons.
All that said, if you're not going to load a lot of ammo at one time the Dillons aren't what you want.
