Best die for de Prime and re size together

[Raiderh20boy]

Just wondering what is the consensus opinion on what is the best die to use for removing used primer and re-sizing used 9 mm brass. This would be on a Dillon XL650
Thanks for you input in advance !!

I have a lee single stage that is exclusive to deprime followed by wet tumble. (Lee universal decap for pistol and smaller rifle cases) Rigging a case feed to it would be awesome!
It's just easier to foul, clean and then relube the single stage than constantly detailing the dillon.

The Dillon decap resize for 9 is top tier. Cost About $100 right now for a full set on ebay

OP - you may know some or all of this. Hope it might help someone that doesn't.

Lee has come out with the APP press. It looks really handy for sizing and decapping, and can be set up with a case feeder. It can also be set up to swage cases (primer pockets), also using the case feeder.

Some of the Dillon sizing dies have a larger radius at the bottom of the carbide ring. If one has one of those dies, and badly bulged brass, it can leave the bottom of the case a bit oversize/cause an issue. If your brass isn't bulged or expanded much, this might not matter to you. I've used Lee dies (even in Dillon presses) because that radius was smaller.
One thing that can help - tumble in walnut media first, with just a bit of liquid car wax in the media. Let the media run for a while to distribute the wax, then put the brass in. This will leave a teeny bit of lube on the case, making sizing easier.
The 9mm case is tapered a fair bit, and takes more force to form. Straight stuff is easier.
9mm brass varies all over the place too. 9mm barrels are also all over the place as far as chamber size and bore diameter. Getting the right bullet can make a huge difference in accuracy.

They all do the same thing.

Most of my pistol dies are Hornady.

Many hate Lee's lock nut.

Most my rifle dies are Redding (except for adding Lee collet dies for neck sizing)

Mighty Armory makes the best depriving dies hands down. The pins are centered and virtually indestructible.

I use Dillon dies on my 650 without problems

That can be said of really about any die.

This is commuting at 65 mph in light traffic. VW or Ferrari both accomplish the task equally.

Someone didn't read the OP...

Just about any 9mm sizing die will size and decap. How well they work depends on how well you set it up and how well you get to know its idiosyncrasies.

I'd suggest carbide over plain steel (assuming you can still get plain steel.) Not having to lube is nice. I'd also suggest a major brand, as replacement parts are easier to source, should that become necessary.

My father uses Dillon dies, and they give his 9mm cases a weird Coke bottle shape. Not a fan.

The Coke bottle shape is actually an indication of good case neck tension in reloaded cases.

I think Dillon's sizing die is the best.
It has a spring loaded decapping pin that throws the spent primer off the end of the pin so the primer can not be drawn back into the case like sometimes happens with non-spring-loaded decapping pins on other brands of dies.

the Dillon die is really nice, I have the 45 die set & I like the theory behind the spring even though it sound funny when running the press - I use an older RCBS carbide die because that is what I have... I have used to Hornady but I didn't like it, my go to is usually Redding but since I already had the RCBS and it works I didn't see a need to replace it

Then you also know about how easy Dillon dies are to clean or swap seating stems without losing adjustment due to how the seating and crimping inserts are held in with clips.
And how the huge funnel on the seating die will turn a bullet 45 degrees and straighten it before it seats like almost no other brand seater die will.
