Hornady taper crimp vs regular 9mm dies - which one??

[JustinN]

Last night my local bass pro shop had hornady nitride 9mm does in stock - I've been waiting in 9mm dies for MONTHs. I went ahead and bought them, then realized the ones I had on back order are the new taper crimp edition. The ones I brought home dont say anything about taper crimp, so I'm guessing they're not. Should I return these and just keep waiting on the new taper crimp edition, or will I be ok using the old style to load up 9mm rounds?

9mm like any rimless case headspaces on the mouth of the case. So a roll crimp won't work, you need a taper crimp.

I don't now of any 9mm that would ever want or need a roll crimp so I'm thinking the dies you have should work.

If nothing else you can set with that set and get a Hornady Factory Crimp die to crimp if you feel the need. I like the Factory Crimp Die anyhow. I set with a regular seating die then full length size and crimp with the Factory Crimp die.

With or without you should be able to make the set you have work with the proper adjustment.

As Bawanna says, The dies you bought will taper crimp. It is just a matter of adjusting them. The instructions will give the correct settings for a taper crimp. They can also be adjusted for a roll crimp but you will not need that adjustment for 9mm Lugar.

Gotcha, so the new taper crimp dies just take the fine work out of it for you. I was thinking these would work since they have been what Hornady sold for a long time, but then didn't know if it was a big enough deal to return them and wait on the others.

you don't really use a cramp on nine millimeter cases. if the expander ball is the correct one, the bullet will be held firmly within the case. the crimp only serves to straighten the flare needed to seat the bullet

Justin we have used these taper crimps for 5,000 round (fired 3,200) without a problem.

Bawanna, I'm curious why do you use both? Is it because you feel it's needed with the 45?
I'm particularly interested because 45 is what we are loading next.

I just like the whole case getting sized and a snug squeeze on the bullet.

I've loaded lots without it but I like that final press where I know everything is within size and it's gonna chamber.

Surely not a must have thing, just a nice thing to me. I'd do exactly the same for 9 if I loaded 9.

Great, thanks!........I like being super cautious and sure that it will all work.

I don't use the crimp ring of the seating die on any of my handgun rounds (.38spl, .357mag, .44 mag, .45 acp), but use the Lee Factory Crimp Die for the last step. I am crimping my 30-30 rounds with the (RCBS) seating die, but planning to get the LFCD for that as well. Perfect crimp, every time.

[Bawanna]

^^^^What he said. That's what I do too. I seat with no crimp then let Lee take over on the last step.

[JustinN]

I think I'll just keep these, instead of waiting at least 2 more months for the actual taper crimp to come available. It sounds like if I'm careful, I can just adjust these down to "taper" crimp the round, but not so far as to actually roll crimp it.

[Ikeo74]

I have been doing it for 40 years, it works, and the ones you have are easier to adjust than the taper only dies.

Now I just have to find my shell holder. I think I threw away my 9mm one as I can't find it. My bench is really neat and it's just not there. I think I accidentally threw it away, thinking it was the packaging to my .243 holder, when I stuck it in the die box. Oh well, at least it isn't an expensive part....just annoying.

[mr surveyor]

Justin, if you buy a complete set of shell holders (pretty cheap) and then buy Lee dies you will always have a back-up (unless you lose the full set of shell holders) You get a free caliber specific shell holder with every set of Lee Dies

[Ikeo74]

Look in your press. There is almost always a shell holder in the press left from a previous loading. I have a cross reference guide that tells if a shell holder will work for more than 1 caliber. If you have others they might work.
