I have a 650 and love it. I too, load thousands at a time. I also have a Square deal. Loads 38 spl like a champ. Can’t get it to load 357’s. Even with that problem(most likely operator error), I would recommend either Dillon.
I certianlly appreciate what they are doing. Being in NY and having to abide by the insane laws of a government that does not understand the conection between armed citizens and a major drop in crime astounds me. As well as outrages me.
