Well, that's why they make different brands of most everything.......
I recently replaced my worn out Pro-Jector with a new LNL press. The old blued .38 Special shellplate moved right from the old press to the new one and works perfectly. The ejector works well, with only an occassional round hanging up, probably about 1 in 500 or so.
I've only loaded 3,600 rounds on the new press, but so far I'm very happy with it, and I'm using RCBS dies, with a Lyman crimp die in the 5th station.
I don't prime on any progressive press, since I consider priming a precise step in making new ammunition, but just for kicks, I did load 100 rounds with the LNL press doing the priming and it was well within tolerances, and all 100 rounds went off as expected.
I find it interesting that some people will swear off a certain brand due to one experience. I've had some pretty rude dealings with Dillon, but I still buy and use some of their tools. I've talked to them at the SHOT Show several times and they are brusk and rude, unless you have invested your life savings in their equipment.
At those same SHOT Shows, I've talked to the people at Lyman, RCBS, Hornady and Redding, and they have all been pleasant and helpful. While I don't limit myself to any one brand of equipment, I also don't exclude any one brand, since they all have a few things they do better than the others.
I got a good deal on my LNL ($299.00 + shipping), and I received 1,000 Hornady .44 XTP bullets for the cost of shipping. In essence, I got the press for free. My old Pro-Jector is back at Hornady right now for a complete rebuild, and when it gets back, I'll then have two progressive presses on my bench, along with my RCBS Rockchucker, my Hollywood Sr. and my Magma Casemaster Jr.
Hope this helps.
