I'm one that prefers the rotary mechanism. Compared to my 550, which has a similar feed mechanism as the 750, the rotary mechanism is more reliable and stays cleaner.Great deal on that Dillon 650 with what is shown in the pick.. The 650 has the rotary primer feed which is what they got rid of when they went to the 750 model. Some love it, some hated it. It requires a little more attention to detail/cleanliness but I have no issues with mine. If you do for some reason set off a primer you’re going to have several going off!! Most reported have been with the softer Federal spp. Press is still fully supported by Dillon so any broken parts the will replace from stock.. Depending on prior use may be worth sending in for rebuild which is fairly priced. If you use allot and downtime is not an option get the spares kit for sure!
