Factory Crimp Die Selection?

Postby Hawkmoon » Thu Feb 19, 2015 11:26 pm

Being a "1911 guy," I've been going merrily along for years just loading .45 Auto, with occasional forays into 9mm. I'm looking to expand my horizons and start loading for both .380 Auto and .38 Super. I just bought Lee dies for both calibers, and their arrival brought an enigma.

Lee apparently doesn't offer 4-die sets in either of those "calibers" (yes, I know they are actually the same caliber). I bought a FCD as a separate part to fill out the .38 Super set, but I was thinking I'd have to get along with just three dies for .380 Auto.

Unless I am misreading something (and I read it three times), Lee claims the SAME FCD works for both .38 Super and .380 Auto. Does anyone know if that can possibly be correct? The bullet diameters may be the same, but the case diameters are NOT the same. .380 Auto has an almost straight case with an O.D. of 0.3739 just forward of the extractor groove, and 0.3731 at the forward end -- and a crimp diameter of 0.3730.

.38 Super IS a straight case, with an O.D. of 0.384.

Assuming the FCD is correctly sized for .38 Super, what -- if any -- purpose would be served by running .380 ACP rounds through it after loading? It looks to me like that would be a waste of time and effort -- and certainly not buying another of the same FCD so I can keep two turrets fully set up.

Opinions? Has anyone played with the FCD for either of these calibers?

I use cast lead boolits and have no use of the carbide factory crimp die as a post sizer since the lead deforms and does not recover after the die has done its deed. With your long term experience, I bet your ammo is not in need of post sizing anyway, its probably dimensionally correct already. I would buy a separate crimp only die and go from there.

I use the FCD for both .380 but I'm using jacketed at the moment. What I did when I loaded with cast is to set the FCD to just remove the bell on the brass, worked very well.

And l like checking all pistol brass with cartridge gage. l seat coated lead and useing cart gage have found FCD to be even better than my dillon die or hornaday's l have owned.

Since nobody seems inclined to answer the question, I went to Lee's web site and found that they do sell different FCDs for .38 Super and .380 Auto. Now I need to figure out which I have, so I can order one of the other.

Lee stamps a product number on the dies, read the one you have, order the other.
