I never really thought about being aDillon fan or not, but I havea650 ,550 and3 square deals and use them all, I also have the RCBS 5 other single stage presses, from the early 60,s. Have found that their service is the same as the other company that I have.The only real surprise that Had was when Ifigured out that Could load sub quarter inch moa ammo for my LBC varmint rifle. the great thing about the Dillons ( for me anyway) was that Could make a lot of ammo quickly. I used to shoot 25,000 t0 30,000 annually, so time was very important. Now except for the 556 nd the 10mm,s I use 1 of the single stage presses.
