Love my 550 B.I find myself revisiting this thread. I loaded 450 rounds this weekend because it was raining and I needed a break from Hallmark movies. Im trying to decide if going to a progressive and if so which one will be the best bang for the buck. I would love to grab a 650 for 9 and 38 but dont know what I will have to sell to make it happen. I only load 9 and 38.
