Hi,
Does anyone happen to know the outside neck diameter of a ADI/OSA 308 loaded cartridge?
Just wondering what bushing I will need for a Redding sizing die using ADI brass.

Thanks in advance Allan

I bought a bag of 120 just before the lockdown as back up due to the component shortage.

I measured the o/d of a few of the loaded rounds to check whether they would fit my chamber with a .340 neck, the neck clearance is a little less than my usual 0.004 but they chambered (and fired) ok with an o/d averaging 0.3375.

I would use a 0.336 bushing but prefer a Lee Collet die unless neck turned.

Brilliant, exactly what I was after. Thankyou.
