Mighty Armory sizing die.

Gonna recommend this sizing die after using it.

Yes it is expensive. Yes it is worth the money.

I verify my ammo with a hundo case gauge. I've found I have more brass related rejects with Dillon dies. Dillon dies are great, but when you use range pickup brass thats been used a bunch I've found, as have many others have, that Dillon sizing dies don't always get the job done; especially if you have a little bulging toward the bottom. I have had better results from Lee, Lyman, and RCBS sizing dies. I tried this Mighty armory sizing die, and have found it to be heads and shoulders the best yet.
The link above if for the 9mm version, but search around for other calibers.

Just my 2 cents worth.

Is it a straight wall or tapered die, and what press are you running it in?

Running it on Dillon 650.
Here's a few pics for reference.

That’s funny, Dillon promotes their own dies with the big funnel mouths, while this one seems to have just the smallest radius while apparently working well.

Do you lube or run it dry?

I spray mine with brass juice. And if I'm out of that...Hornady one shot.

I use some non-carbide dies I used in the 1960's if I want to size more of the case. The carbide dies are great but just do not go down as far. I do have to be more careful getting the case started into the die. It looks as if Mighty Armory found some virtue in the way we had to do things in the past. That is a good thing.

Agreed. The instructions include a light tough of oil one the inside of the die before use, wiping it clean, but otherwise no lube required with this die.
