Lee Carbide Pistol Taper Dies.

Does Anybody know how these things do the thing it does. Lee Claims that even if your brass has a couple of thou difference in size and as long as it's below Max trim length, it will size the round when tapering. I was loading for 9mm luger plinking rounds and don't usually worry about a thou here and there but as you know when seating and tapering the bullet you will notice the difference in COL between rounds.

So I borrowed this Lee Carbide taper die my mate has and gave it a go. I made sure all the cases were different a thou or two in size. I used cast bullets so they couldn't seat the bullet further down and tapered a dozen inert rounds. Well lo and behold on measuring the COL every one of them was the exact same size. How's that work then?

Fair enough it's another step in the reloading process but in my case it's just one more pull of a handle so no big deal there.

Lee Carbide Factory Crimp Die
Carbide Factory Crimp Die38 Special Die CutawayA carbide sizer inside the Carbide Factory Crimp die post-sizes the cartridge while it is crimped so every round will positvely chamber freely with factory like dependability. The adjusting screw quickly and easily sets the desired amount of crimp. It is impossible to buckle the case as with a conventional bullet seating die. Trim length is not critical so this extra operation takes less time than it would if cases were trimmed and chamfered.

Revolver dies roll crimp with no limit as to the amount. A perfect taper crimp is applied to auto-loader rounds. The crimper cannot be misadjusted to make a case mouth too small to properly head-space. A firm crimp is essential for dependable and accurate ammunition. It eliminates the problems of poor ignition of slow burning magnum powders.

Depends which one it is you are using.

Lee 9MM LUGER/38 SUPER/38 ACP/380 AUTO Taper Crimp Die, overcomes crimp problems caused by poor die design. Offers little or no advantage when used with 1986 or newer Lee Dies as the crimp angle is already a modified taper crimp

Alpha1, yeah I know all that, but how does it size it when crimping is the question. No other crimp die sizes the round as it tapers it.

I reckon if LEE could put a bullet seater in the die as well and it did what it does now, they could be onto a real winner there.
