Turn necks on virgin brass?

Should I wait until they are once fired then turn the neck or just do it right out of the bag?

Thanks

Do they really need it?

What is the variance? If not a wide variance, then why? By better brass such as lapua and it will not be a factor for a factory SAAMI chamber.

Do you have bushing dies?

If you find that you need to, then resize them first.

Use the matching expanding mandrel for the particular neck turning tool to expand the necks to the cutting mandrel diameter.

Then neck turn.

Do it BEFORE fireforming, after sizing & mandrel expansion as BH said.
This is just what shooters with tight neck chambers do(so loaded necks fit into the chamber). They also turn a bit into the shoulder to eliminate doughnut potential.

If you don't need to turn, but just want to reduce runout, turn only the high spots.

Why turn...... Why not? Consistency, right? All it takes is time....

Ditto BH & Mike

Turn first but you probably will have to expand the necks so you can get the turning mandrel in. It depends upon what kind of turner you have. I have the Forster turner and run the cases through a Lee Collet Neck Sizer and it is just right for a tight but not too tight fit. The new cases are typically too tight for the mandrel and if you use an expander ball for necks then that typically does not open the necks up enough for the mandrel.

Consistancy does help in any aspect of reloading. Here was a good previous discussion

To turn or not (necks)

especially the most recent posts.
