I just have the redding 2 die sets and neck size with the full length die.

I am going to get some Redding neck size only dies.

Do they come with decapping pins? Or can they be used to deprime?

Nevermind. Just called redding and the neck size die does have a deprimeing pin.

Why go with Redding? For less than the Redding die alone you can get a Lee Collet set and more than enough left over to add a Factory Crimp and a box of bullets. Unless you have a match rifle with a tight neck chamber, it doesn't make sense to me to spend the extra money.

I like redding, thats all I own , Dont like Lee's. Not worryed about scronging for pennys!

$20 bucks for redding neck die.

I agree, I assumed you were talking about the fancy ones with the replacable bushings. FWIW though, I have tried Hdy's, RCBS, and Lyman neck sizers, all comparable to Redding's standard NS offering, and they all give you much longer case life, but none have produced more accurate ammo than Lee Collets. No comparison, not even close. Some of Lee's other tooling I'm not too trusting of, but their dies have stood up under very hard use for many thousands of rounds and I have no complaints with them.
