Hey all, I've been doing a lot of reading and I will be buying the following straight from Dillon's: RL 550B Caliber Conversion Kit to be Included: .500 S&W Magnum * - $10.00 Dillon X-Large Powder Die RL 550B Spare Parts Kit Dillon's RL 550 Toolholder w/Wrench Set Dillon Carbide Pistol Dies (Three-Die Sets) Die Type: .45 ACP/GAP - $63.95 D-Terminator Electronic Scale Primer Pickup Tubes, 2 Small, 2 Large (I'm assuming I need the large ones for the .500 S&W since it uses large rifle primers) Digital Caliper Dillon's CV-750 Vibratory Case Cleaner CM-500 Case/Media Separator Walnut Hull Polishing Media Rapid Polish 290 (8 oz. Bottle) Do I need to get a case mouth deburring tool? Also I'm a little confused about what people use for cleaning media. Some people seem to start off with walnut then finish off with corn cob for added polishing. I don't mind polished brass but all I really care about is smooth feeding functional ammo, and if extra polish adds an extra step in the cleaning process, I'm not really interested. Also I read some people mixing paint thinner or car polish in the media, how does Rapid Polish 290 compare to that? Others "condition" the media. I understand that people have their own recipe but I'd like to at least start off with a tried & proven technique. Let me know if I'm missing anything, I'll be starting off with .500 S&W and .45ACP. I'm ordering the Lyman 49th Edition book off Amazon. Thanks!
