So I come home to work to all of this! My roommate made a run home and brought back almost all of their reloading supplies. We have a press for shotgun shells and a single stage for rifle/pistol. The 3 main calibers we're gonna do right now are .223, 9mm and 22-250. Now I reload for my .308, or used to when I lived with my parents so I'm not a complete stranger to it but I am to when it comes to using used brass, all my .308 brass was new as a gift. How do I go about cleaning it without a tumbler (I've heard of the simple green and water) and do we need a case trimmer or can I just run it through the resize die when I extract the primers? Also, what are some of y'all's loads? We both have 1/7 twist barrels in ARs and right now we have 200 55 grain bullets and 100 53 grain bullets. I also have about a pound of Varget powder from my .308 that I've read from Hodgdon's website is good for .223 as well. Thanks for the advice in advance!
