RE: Made the decision; Now Need Help
From my experience I would recommend Dillon Precision equipment. I have the AT500 which is a turrent model that can be upgraded to the RL550. But I don't reload in sufficient quantity to justify (nor do I like) progressive reloaders.
But for reloading a number of different calibers, I like Dillon presses. You can purchase tool-heads for each caliber or rifle that you load for and never have to re-adjust the dies. Plus you get Dillon's No BS guarranty. Once you buy a Dillon you will have it forever. They are tuff but still made to be repaired or upgraded.
Sportsman Warehouse sells the RL550 and all the parts that you might need. Some other major sporting goods dealers also handle Dillon.
