One more question... With the 550 you can use the current dies I already have , correct? But I have read sometimes their a little short in the tool heads. ( Lee for pistol and Rcbs for rifle ) any problems use non Dillon dies..? When I order it I am going to have it shipped with Dillon 9mm dies for it but when I want to load .38spl etc, I would like to use my dies and just get the caliber conversion kits , it would be alot cheaper if I could... Or are you better off just buying new dies from Dillon..?
