LOVE my Dillons, like the versatility in being able to switch calibers so easily. That said I ended up with seven Dillons and had each one dedicated to a single caliber! Their weakest point and what caused me the most problems is their primer systems, but what hooked me on them was the RL1050 which swaged the primer pocket on military .45 acp brass at the third station. When I started IPSC/USPSA in 1982 everyone shot a Colt .45, however brass was very scarce in Canada and the only brass available in any quantity was US military with crimped primers. The 1050 was great, it manufactured perfect .45 ammo from once fired military brass! The primer system caused a lot of headaches until I replaced the plastic ends on the primer tubes with turned brass fittings. My new-to-me Star progressive primer system has been perfect in my brief experience with it, and I can see the beauty in the powder system and the fixed charge bar. In fact I have pinned two of my Dillon measures so they are fixed and cannot come out of adjustment.
