Bushing for Redding 280 Ackley Improved Competition die set.

[Vinjesvingen]

A gunsmith is building new custom rifle in 280AI to me.
I'm going to order 280 Ackley Improved competition die set, i have 280AI brasses and Berger 168grs bullets,will also use Nosler Accubond long range bullets when I get these.
Can anyone tell me what bushings i need for this die set?

No one can give you a correct answer without more info.
Do you use a custom reamer, and what is the diameter of the chamber neck?
The bushing you need is also dependent ob the brass you use.
And your desired neck tension.

Can not measured neck, my gunsmith has borrowed reamer of another gunsmith, but believes it is a standard reamer.
Brasses i will be using is Nosler.What is recommended neck tension?

A 307 and a 308 bushing should be a good start.
