I traded up to a Dillon 550 in 1991 and load about 5,000 rounds per year in 223,308 ,30-06, 9mm. 38 special, 40 S@W and 45 acp. I am really happy with the 550 and Dillons warranty [RIP Mike] has been truly no B.S. i taught several people how to load on the 550 and they are all now very competent loaders.
