Just received 100 new Lapua cases in 308 Win.
Should I just load them up and shoot, or would you do any prep first?

Prep for new brass?

I run my new brass through every step of the process except cleaning it. I've had a couple of Lapua cases with slight dents in the case mouths from handling.
I don't bother with uniforming and de-burring primer pockets with Lapua, I've never seen a bad one yet.

I was in the same boat as you recently trying Lapua for the first time in 6.5x55. I took measurements on about a dozen and found them to be, well, perfect. Almost perfect maybe...
In the end all I did to them was run the necks into a Sinclair mandrel die, debur and chamfer.

Just 100 Lapua brass?
LOL Just kidding.
For my F Class loads with the 308 Palma, I will just expand with 21st Century Expander Die, then load and shoot virgin brass. I always seem to find that Lapua in 308 (and 223 match) are very tight necks out of the factory
After that first fire forming:
SS wet cleaning,
Induction Annealing,
0.002 shoulder bump & 0.002 neck tension with Redding Dies,
neck turning (lightly about 0.0015),
3 way trimming (leaving them as long as possible),
Primer Pocket Uniforming (shave about 0.001),
Flash hole deburring (with a 21st Century tool),
Rinse in Alcohol to get all the sizing wax and brass flakes off
Sort by weight and break out into 4 lots of 75 brass.
After all that.. take to a local Priest so they can be blessed and they are ready for competition usage.

I too find virgin Lapua (making them sound heavenly now) have rather tight necks out of the box. But they're still virgin so that makes sense, right? Like others I chamfer new brass and will neck size any that are dented.
