I have the LNL and think it is an outstanding press. HOWEVER, the hardest part in learning to use my press was the adjustment of the Powder-Thru-expanders. The instructions are not very clear on the subject. In order to get proper "belling" on your cases AND consistent powder drops, you have to loosen the clamp on the powder die to screw your powder measure deeper into the die. To get consistent powder drops and belling, the linkage on the powder measure has to cycle to "top out, over center" on each stroke of the press. As far as sizing/bullet seating/crimp die go; any manufacturers dies will work EXCEPT, many taper crimp dies are a little too long and will hit the case ejection wire. Especially the LEE crimp dies. The easiest solution is too order Hornady taper crimp dies. They are a little shorter and do not hit the ejector wire. OR, take your existing crimp die and a Dremel tool and grind a small flat on the side of the die where it hits the ejection wire. Looks rough but, works great. Don't let anyone tell you the LNL is not a great press with great customer service. It's just that it has it's quirks, just like the Blue presses. Both are excellent!!
