I read that article several years ago. I wish I hadn't because it helped reinforce my choice of buying a LNL AP. I returned my LNL. To be completely fair had I not owned the 550 for several years first I would have spent more time trying to work out the issues I was having with the LNL. If you don't want a case feeder and your not spending 90%of your time loading 9mm then it is still a viable choice.
I would describe the differences as the LNL AP being home owner quality were as the Dillon is commercial quality.
If you are going to buy a case feeder the price is so close you might as well opt for the commercial quality one any way. I am going to agree with Brian Enos and say that the vast majority of reloaders should just buy the Dillon 550 and done with it.
When dealing with Democrats, let us remember we are
not dealing with creatures of logic. We are dealing with
creatures of emotion, creatures bristling with prejudices
and motivated by pride and vanity.
