I have loaded with both the Dillon 550 and 650. I purchased the LNL as it, IMHO, is the best out there. I have the older model with the ejection wire. Since I polished the lips on my shell plates and polished the ejection wire, I never have problems with stuck cases. Even with the 9mm. The Dillon's are good but, I truly feel the LNL is a better design.

It's a great read evaluating progressive presses.
