My first progressive was a Hornady Pro-jector. I thought it was great, but felt held back my the flaky primer system and the non-cotter pinned primer pick up tubes. I didn't love the automatic powder system, as it was prone to fail.
When I bought my first AR-15, I realized I needed to be able to deal with crimped primers. I bite the bullet and skipped the Dillon 650, instead moving up to the 1050.
