Ive owned my Dillon 550B for about 10 years now. Ive loded probably 20-30k pistol rounds on it. Other than keeping her relatively clean and lubing where needed once in a great while, how long can i expect the machine to survive? Any parts wear out faster than another? My gut tells me that this machine will outlast me and then some. Any recommended spare parts to keep handy? This machine has been the gift that keeps on giving.
