Keep your Lee stuff, its works just fine. You should be feeling the case mouth when you adjust the screw down on the FCD. If you don't, something is either wrong or you don't have the body of the die screwed in enough. Run it down until it touches the shell holder, then back it out ever so little (so the shell holder doesn't hit it when on the "up" stroke).

Nothing wrong with Lee dies. Actually, they have a couple of features unique to them that I just wouldn't want to be without now that I'm used to them.
If you do in fact have your factory crimp die adjusted right, might start looking at your expander die. I assume you have the " powder thru " expander... Lee dies are great, but at times some componets can be a bit out of spec and also the surface finish a bit rough. I had fits with the Lee expander for .357 sig and ordered another one. The problem was I was not happy with the neck tension on the bullet and how rough the expander would enter / leave the case mouth. Come to find out, the finish was very rough on the expander plug itself, so I just very LIGHTLY polished it on a nylon buffer. It didnt take more than .0005 side to improve both issues ! Might pull your expander plug out and mic it. Since then , I have lightly polished every expander plug I have bought. I wouldn't attempt this unless you have a decent set of mics. You dont want to remove much . If you take out the machining marks, you went too far ! Just hit the high spots lightly. As an added bonus, this will also make your powder measure work MUCH smoother and consistent if you have one mounted up top the die.
Oh don't even think about tellin me i need NEW equipment!! I've just about had enuff of this reloading crap i can stand. ITS SUPER FRUSTRATING!!! and what the heck is a taper crimp? the funny thing is i made prolly 100rds last week that were perfect,didn't even need the "Factory crimp die" Then i get some more of the SAME bullets and i'm having this problem. are 45 rds this darn finicky? has anybody had trouble w/rem. brass?
