Hornady LNL Dies?

[hmvan]

For those familiar with the lock n load, what is the difference between the 9mm taper crimp die set and the standard? I can't seem to find the difference.

Thanks!

Taper crimp and roll crimp.

A roll crimp is just that. A rolling or the brass in to a cannelure of a bullet. Hopefully at bullet does have a cannelure for this type of crimp. Usually for a rimmed revolver cartridge. Now a semi auto cartridge chambers against the case mouth and thus requires a straightening of the flare or a taper crimp.

It seems that both the dies for the 9mm are actually taper, but one die seats and tapers the round while with the standard die, you need 2 separate dies: one for seating and one for tapering. am I wrong? I'm getting ready to purchase Hornady and want to make sure I get all the right equipment to start.

the standard die will seat and taper crimp and there's also a taper crimp only die that's hollow looking and the cartridge goes up in it to taper crimp. I prefer to seat and crimp in 2 seperate steps so i set my taper/seat die to only seat the bullet then use the seperate taper crimp die

Thanks! This is helpful. Is there a benefit to separate steps? Or personal preference?

The benefit is that when you seat and crimp in the same die that bullet starts being crimped before it is fully seated so you can get bullet shavings or issues with brass, it isn't extremely common but it does happen. When you seperate the steps then the bullet will be fully seated before you even start the crimp this eliminating the chance of any issues. I did many thousands of rds seating and crimping in the same die and only had a small amount get damaged, but once switched to seperate steps then i havent had a single failure

Be aware that Hornady offers two die sets for the 9x19mm cartridge.

Both sets come with a Seating Die that both seats and crimps in one operation. But one set comes with a die that roll crimps and the other with a die that taper crimps.

You want the set that has the die that applies a taper crimp while seating the bullet...otherwise you'll need a separate Taper Crimp die

Well, I really like the Hornady handgun dies for their Seating sleeve (in the seating die) as it makes keeping the bullet upright easier when raising the ram.
I have found their resizing dies to be smaller dimensions than my other die sets (Redding, RCBS, LEE , Bonanza) and I often get that bulge line in the brass from base of the seated bullet and upward. For functional ammo it works pretty good but Often I will wind up with several die sets to load one caliber as I prefer different dies from different manufacturer's. Most caliber I have a Lee Factory crimp die to deal with the crimp and I like the Lyman M die "flare die" more than Hornadys dedicated expander die or their PTX expander.

Anyways you could just get the Hornady die set then add a Lee factory crimp die and get a taper crimp die that is very good.
If you really need the extra station for powder cop die then do the PTX type expander to expand and powder charge in one step. That would free up the die location for a dedicated crimp die.
