2010s 2nd SD in .45 acp After 200k plus rounds SD sent back in for major rebuild last year at Dillon's request. Now back in service with no issues. All 4-5 calls about problems over the years answered with professional advice and parts at NO CHARGE to solve issues. Getting ready to order a 550 or 650 so I can automate a little to expand into some rifle cartridges (223 mostly). Thinking I may like the non auto index feature for rifle work. For mass produced pistol cartridges, you can't beat the SDB! Do I own other presses? Yes, one 1973 Lyman Spartan used last night to load some 44 mag. Still does great job, but redundancy boring and slow. Getting old I guess.
