I plan to have everything completely interchangeable, within reason.A bit of advice.....Get extra powder measures. I intend to have one for every caliber I load. At a minimum have 1 for rifle and one for pistol. Easier to swap between when the powder is set up already.
I love my 550. I got it used in a good trade.
Jim.I have been moderately happy with my Dillon 550. I bought it new last April and have had consistent problems with primers loading upside down, sideways and none at all. I have loaded over 25,000 rounds through it and have had this problem from the beginning. Otherwise, I am very happy with the machine.
