I wouldn't start with a Dillon unless you absolutely will be shooting thousands of rounds a month, and not doing much loading for a specific purpose other than practice ammo. If you will want to work up target or hunting loads get one of the smaller presses. If you're going to be crafting precision rounds, you'll hate the Dillon. And you might love a C or O press. Starting with a progressive is a good way to get to hate reloading. I've had a Spar-T turret press for closing on 50 years. Wouldn't give a Dillon bench space. My brother shot competition for decades. I think he's got 4 or 5 Dillons. Couple 550s, a 650... Not really sure as I've not seen his setup since about 2010. He shoots AR's, M1A's, and 9mm, and used to keep most of the brothers & sisters, and their kids, in ammo. If you're going that route, you might want to spend time around someone like him first. He was talking to me about needing 8 identical sets of molds for a Magnacaster, the other day... I have maybe more than a dozen molds. But none of them are the same. Think no more than 3 are same caliber...I'm going to purchase a used Dillon 550 progressive press. The owner has past away and the wife is selling all his inventory. My problem is I don't know what all I need to start reloading. The basics I get, a press, dies, brass, primers, powder and projectiles. Beyond that I need some guidance. So starting with the basic 550, (there was not any accessories, or attachments on the press.) What is the basic necessities for making boolits? I will be doing rifle and pistol calibers. All feed back is welcome. As a thank you for you insight, once I have purchased all necessary equipment. I will share the rest of the loot with the group. I was told the husband had over $50,000 in reloading supplies and equipment. It's all going to be for sale after I get mine.
You might be somewhere between us.
