223 lapua brass

[Stephen curry]

The last two boxes of lapua brass iv bought have had very tight necks out of the box.whats the best way too sort this.thanks fellas 

[Catch-22]

Use an expander mandrel (die body and calibre appropriate expander mandrel), one by Sinclair, 21st Century etc.

Always a good idea on new brass as it straightens necks, pushes brass inconsistencies to the outside of the neck and improves neck tension (usually gives 0.02” tension).

Here are examples of the expander die. You will need to add the correct calibre mandrel too;

Btw - I have no affiliation with the retailer, just what Google found.
