9 mm Carbide sizing die

[Ben]

The 9 mm Luger case is tapered.
.380 at the mouth of the case..........391 at the base of the case.
How does the carbide ring in the sizing die
correctly size the top and the bottom of the case to the proper dimension ?

[JRR]

It doesn't! Find a brand of non-carbide sizing dies (needs lube) that has the proper dimensions. I'd start with RCBS, but there might be other brands that have an educated customer service dept. that can answer the size questions and get you the proper die.

It's not really a "ring" (which most take to be constant ID and OD along the length). I just examined my RCBS 9mm sizing die using pin gauges. It's clearly tapered inside. So, think of it as a tapered liner, not a ring.

It doesn't!

Are you saying that carbide dies don't size the 9 mm Luger to proper factory spec. dimensions ?

Is this tapered liner made of carbide ?

Ben,

Yes. We often refer to it as a "carbide ring". For straight-walled cartridges, it likely is. I never checked any dies for taper until your post.

For 45 Colt, the case is specified by SAAMI as cylindrical, but the chamber is tapered in the spec. The spec for 9mm Luger shows both case and chamber are tapered.

Thanks for the info.

Best to you,

Yep, it is kind of a compromise and apparentyly it works well enough but it doesn't resize to SAAMI specs.

But it's better than using the "greasy kid stuff"./beagle

Twenty years and many thousands of rounds later, using a carbide sizing die for 9x19 was one of the best choices I ever made. There are no absolutes; everything is some sort of compromise. If it works for you, like it did for me, go with it. They're too cheap not to at least try one and see if it's a fit for you.

The carbide insert is tapered to match the taper of the 9mm case.

It solved ammo feeding in all 9mm pistols I own.
It did not promote accuracy and it now sits unused.

It will be used for 9mm Uzi shooting loads from now on
as accuracy with that thing is angle of man.

The only way I can see this die doing swell is if your bore
in the pistol is .355 and you carbide criimp die is .356.
Thus your cast bullets do not get swaged and accuracy is
not effected.

In 45acp: I saw no gain using the carbide crimp die and ceased
using it. I had no problems with 45acp loads and cast bullets before
and bought the carbide crimp die out of curiosity. It proved to be immaterial
in my reloading... did no harm and did no good . I had no problem with
45acp so there was nothing to fix. Wasted time and money but curiosity
was satisfied.

milprileb,

It sounds like you are talking about the Lee Factory Crimp Die (FCD).

The OP was a question about carbide sizing dies.

[milprileb]

Pardon me: I thought this was about carbide crimp dies.

I apologize. I just re read and am flogging myself.

All shots aimed at me are justified !!
