Using a lee collet die for a mandrel

[Defender3]

I don't see 300PRC offered, would I have to go the custom route?

You might have to go with custom, it will takes 4 weeks minimum.

Ok so the preferred theory here is body die and collet die. I'm tracking there now

What is the main benefit / reason for using this arrangement vs a type s die for example?

No need to turn necks as the collet die sizes the neck ID based off the mandrel diameter. Bushing die sizes the neck OD so needs consistent (turned) neck wall thickness to produce consistent neck ID’s.

They might be close enough to the same length that a 300WM collet die would work. If I had a piece of 300PRC brass, I would run it my collet die and see.

Thanks for the thought. I sent Lee a question and they stated I need a custom die - 8 week lead time. Guess I'll gather the cases and projectiles and send them in.
