Let's be honest here, the Dillon 650 is faster and more convenient if you need to crank out quality ammo quickly. Provided that you can afford it, it's the way to go. In the case of the OP, this is pretty evident.
Reloading, however, involves a few more factors. Most of us reload because we save money through it. Then we find out we can also tailor our ammo to our particular needs. Win-win. One of the factors involved is how much ammo we need on, say, a weekly basis. In my case, 150-200 rounds do. And I can afford to spend a couple of hours per week doing so. With that in mind, the LCT was my choice and I think I made the right decision. I considered the 550, but, again, with my ammo needs in mind, I disregarded it. I could buy my LCT kit, plus dies, plus ammo, bullets, primers and powder for the price of the 550 and still have some money left in my pocket. Quite a bit, if we consider that the LCT Kit includes a scale and powder measure accessories. Besides, I'm a newbie, and the LCT is great for me. I can go slowly and make sure I'm doing things right. In a progressive, too many things are going on at the same time, it's easier to screw up. And we all know what are the consequences.
This said, and for those who are thinking in getting a LCT, I strongly suggest the Lee Adjustable Charge Bar. It's an optional piece of equipment well worth its price. It allows to tailor your powder charges to a tenth of grain easily. Even less, from what I've learned, and no fiddling with the disks.
At my very relaxed pace, I could make a 100 rounds in an hour, no sweat. I can see myself at 150 rounds per hour soon.
Question for you experienced reloaders out there. I plan on purchasing a rifle (still have to decide which one, though) in the future, and I'll obviously reload for it. Do you think the LCT is strong enough to fully resize rifle brass?. I know it is for neck resizing, but I wonder whether it would be able to handle the stress of full resizing or if I'll need to buy a Lee Classic Cast for that task.
