380 Hornady die problem

@NMexJim, thanks again for your input. I'm glad to know it wasn't just this newbie imagining things. I have things dialed in to produce an acceptable load at this point, but I think the process was more finicky than it needed to be. I guess the disappointment for me is the failure of Hornady to disclose this on the packaging as there are other options in dies that I probably would have preferred had I known (assuming a market where I could find them). In truth, part of my struggle is probably attributable to the Acme bullets which I have read good things about, but they do seem to like to be seated on the deeper side which, without the benefit of experience causes a newbie like myself a little pause regarding pressure. While I would obviously like to be as precise as possible when reloading, I feel like my margin for error has been slightly reduced in this scenario. I sent a message to Hornady through their web contact form, mainly suggesting they consider being more forthcoming in their packaging and will follow up here if and when I get a response, but being just one guy and a newbie at that I don't expect to effect much change.
 
Acme bullets and, for that matter, most aftermarket bullet manufacturers that I've used make good products. Yep, there sometimes a learning curve as most don't provide loading info. But, that's part of the process.

I don't like it when these little hitherto unknown discrepancies crop up, but I've seen a few over the years.

I'll continue to poke them too. Enjoy your loads!
 
I just found the same thing with a set of Hornady 9mm dies - roll crimp with the set. When I tried them, I did manage to just turn the die in 1/16th turn from contact to put a light crimp on my test rounds, and they all seemed to come out fine and plunk good though. I also don't bother to seat and crimp at the same time - just too much going on and for whatever reason I have better success if I separate the steps. It just frustrates me too much to try to get both seat and crimp dialed in, so - I don't bother and do each step by itself now. Depending on the bullets, and how much crimp - at the same time can also shave brass or lead, or bulge the case - blah .. not worth it to me as I'm no expert, just want a finished bullet, not a merit badge on finicky die set ups. .
 
Getting a set of RCBS .380 dies, or a replacement seater with a proper taper crimp, or a separate taper crimp die if you have enough stations is a better answer than trying to use the roll crimp built into the Hornady sleeve.

I certainly agree - foreknowledge prior to the Hornady purchase would have been superior to the hindsight I have now :)

Hopefully this thread helps prevent the same mistake by others.
 
Tomorrow will be one week since I reached out to Hornady via their web contact form. No response yet.

Mr. Sefuller,

I had Round 2 with Tech Support in the honored personage of Jason today. Know him? He and I are developing quite a relationship (not so much actually!). Anyway, I'll relate what transpired. BTY, Jason is trying - to hang onto his temper.

First, let me restate that I've had no issues crimping w/ my die set that's identical to yours. I do not crimp with a heavy hand, not 9mm, .40, etc., and especially not .380. I just don't feel that heavy taper crimps add any benefit.

Anyway, I sat down today at my reloader and started in with jacketed and lead bullets. I used a chamber gauge. When my eye said I had a good taper crimp and when the rounds dropped into the gauge nicely, I mic'ed the taper and it was .374/.375. As the specs state .373, I thought I'd try for just a little more and readjusted my seater slightly downward. At that point, of course, the dies started to roll crimp and I barely had any mouth exposed. A touch more and the case buckled. These were as slight, minimal adjustments as I could make.

At that point, I called my buddy Jason. I asked him how was I supposed to get a taper that would go .373. We entered a Mobus loop and around and around we went. He said that they had researched the issue and that a taper crimp was not offered in .380 because of the shortness of the case. Sound familiar? I said that RCBS did, and he said that, no, they didn't. Yes they do, no they don't ....... Then, we went into the truth-in-advertising issue, and basically the short of it is that nowhere does it say taper crimp and buyer beware. Flash Point!

I said I wanted to return the dies. Jason said that I could not return them to Hornady, but would have to go through my supplier.

BTW, as an aside not central to this issue, Midway (and I do a fair amount of business w/ Midway) agreed to take the dies back. I think they'd just eat them and wouldn't address with Hornady. Since there are no alternatives available, I stated that I'd hang onto them, get another set when I could from them, and just throw the Hornady in the trash. Oh, a glorious day to come!

Back to Jason. After the call, I started in looking and, low and behold, Jason is right (God, I hate it). RCBS nor Lee offer a three die .380 set w/ a taper crimp. I swear I used to own one (If anyone can find a .380 set with a taper crimp, I'd like to know because I told Jason I'd be BAAACCCKKK). You have to get a separate taper crimp die.

I knocked out a couple hundred of both bullets at .374/.375 but was loathe to waste SPP on .380 and so quit. I will have to say I still like how Hornady dies align a bullet.

So, that's my story and I'm sticking to it. I know when to take my elephants and head back to Rome. Should you call Jason, be sure and blow him a kiss for me!

Over and out.

I do believe that my Dillon .380 acp 3 die set is a separate taper crimp.

All Dillon Pistol Die sets include our sizer/decapping die, seating die and a separate crimp die (taper crimp for auto cartridges, accu-crimp for revolver cartridges).

The above quote is from the Dillon website, but I do have MANY sets of the Dillon dies sets---They do have taper crimp dies for semi-auto and roll crimp dies for revolvers.
 
My Redding’s have a taper crimp die and it even says so in their catalog.
If Hornady can’t figure out how to make a 380 Auto TC die, buy from someone who can.
 
Thought I just saw some RCBS series b dies in 380 that listed a taper crimp. That said, I don't think I'd be losing a lot of sleep over it if the dies are creating ammo that works in your gun. Won't be tossing my Hornady dies any time soon. Good luck.
 
@NMexJim, oddly enough it appears that the entire internet believes RCBS die set 20415 has a seating/taper crimp die, however the RCBS website states it has a roll crimp. I have no idea if this is a change or the way it always has been. Your experience is exactly like mine, I can adjust the Hornady die to produce the same dimensions you are achieving, but going a fraction lower with the crimp adjustment begins to create a roll. I shot almost 100 rounds yesterday without issue so I guess I will carry on. If problems develop going forward I imagine a factory crimp die would be the next step.

Glad you're having success. Yes, this has been an eye-opener. I tried to find a Redding Series B 92170 which is indeed a .380 taper crimp/seater today w/o much luck. A bit pricey - more for the seater than the entire Hornady set, but that's ok. I have a query into Redding trying to find one for sale. Maybe within the next year or so. If I lay hands on one, I'll let you know what I think.
 
Your welcome.

Note: The carbide size ring is not designed to be removed, but can be.
If you are mostly loading lead you might want to remove it.
(no putting it back however)
Die should be about $25 so $40 is a bit steep, but they are available.

Anytime I use Amazon I use Amazon smile and my Charity is the California Rifle and Pistol Association. (who have a few cases in the courts so they do represent gun owners in CA as well as possibly other places)
For people who use Amazon you might want to check to see if your local Org is a charity.
 
I own a Lyman 380 set and have never had a problem with taper crimping with them. I might set up tomorrow and see if they do roll crimp and how far down I have to go first.

ETA: The Lyman sets all have a roll crimp on them and you should be buying their separate taper crimp die for automatic straight walled cartridges. I have always used the boxed set from whomever and never yet had a problem getting into the roll crimp part of the seating die. Might be the tolerances of their manufacturing that is a little wider than the taper should be. I will still try and measure mine tomorrow.
