I have had a SDB since the '80s, with 38/357 and 44Sp./44Mag dies and plates, and it is still going strong. Loaded some this afternoon. (It may just be a plain SD, I don't even remember) When I reload high power rifle I do it on an old Lyman C frame single station. I don't shoot those that much and I am extra careful; usually weigh at least every 5th charge, but I don't load anything below .25 caliber. I saw a Rem 760 in 30-06 blow up, up close and personal, and don't ever want to see a replay.
