Crimping 9mm Not Required?

[CQB45ACP]

No! An annealing crimping tumbler with a primer cup swager and flash-hole deburring tool!

Yes!

ETA: BUT! It has to have an annealing attachment that reaches at least 231million degrees Kelvin to make sure full recrystallization of the galactic core takes place.

Thought all that was a Dillon?

It’s one of the flame-thrower topics of reloading. Concentricity, crimping, annealing, primer cup dimensions, maximum loads as starting loads (a.k.a. Manual Discrepancies, etc.), printed manuals vs. online “data” - never minding of course most of the proponents of using online data exclusively don’t seem to know the meaning of the word, “data.” And, of course, the ever-popular, “Do you clean brass the same way I do or are you doing it all wrong?”

Buttons. Some folks got ‘em.

You left out "headspace" and "shoulder bump". Two of my favorite popcorn topics.

Waiter! More popcorn, please!

I do know it’s just people sharing their experiences, trying to be helpful but, dang if sometimes it doesn’t come across as, “There’s two ways of doing things…” etc. That’s why I tell folks, don’t do what I do. Just because it works for me doesn’t mean it’s going to work for you. But since you asked, here’s what I do…

And popcorn is a whole grain so it’s good for you!

The Lee FCD gor 9MM does not use a collet, it Taper “crimps” just like any other 9 MM taper crimp die, and also has the carbide insert that “irons out” the round. The insert would also take care of any flare left over after seating.

Absolutely correct. I would have sworn my 9mm Lee FCD had a collet-type arrangement, but it must have been just my rifle caliber FCDs. I'm sorry to add more chaff to the thread....

I guess that’s enough for this thread. I’ve learned many things including some rather odd things

Thanks to all. OP signing off.

Moderator may shut it down as far as I’m concerned or just let it wither on the vine.

Summarizing post #1: Hey everybody! Look at what I invented! It’s round and you can roll it! I call it, “a wheel.”

They do make some in handgun calibers, but don’t come standard with the die sets, .357 Mag etc.
