Size it, chamfer the case mouth, load it.

I have used it for a while , my experience is that while the brass generally is to spec you will find discrepancies with the necks - which will show up when you try seating bullets and your OAL will be all over the place , you will feel the difference when you stroke your press - so I neck size all the new cases now to get consistency - YMMV

Thanks, I will do that.

I'd drop it in the chamber gauge to determine if it needs sizing or if it's good to go.

You should full length size and trim if needed, I believe it says so on the box to re size before loading. |

Leave your sizing die set up as if you were going to size your fired brass. Odds are you will not get the shoulder "headspace" (head-to-Datum) the same as your fired/sized brass, cuz "New brass is most likely already shorter than your fired and sized brass. Hard to make it grow in that area. |

I load Lapua brass right out of the box and I do not do anything to it. It's the best brass I've used. Never even found any necks out of round.
