The base, body and neck of the Lapua cases have been designed to maintain exact tolerances over multiple reloading cycles. Advanced metallurgical research and manufacturing techniques ensure that Lapua cases are leaders in uniformity and quality.
The most precise cases on the market
Lapua cases are the best in the world. The marksmen themselves think this way. The .220 Russian, for example, is the number one choice of the best benchrest shooters all over the world. All our cases are strong and uniformly precise.
Lapua cases are manufactured to be reloaded, again and again, dozens of times.
The base section is hard and strong, and the dimensions remain constant and will hold primers tight in primer pocket even after repeated reloading.
The brass body section is hard and firm. It is easy to extract after firing, whether full sizing or only neck sizing was used in reloading.
Strict tolerances in concentrity and wall thickness are used in manufacturing. The neck and shoulder are annealed to withstand repeated reloading.

As always the Lapua product is of the highest quality, and being annealed gives a consistent neck pressure. Great Product.
I have not had the chance to reload these yet but I'm told the material composition of the brass that Lapua uses makes their brass the longest lasting. What I have had the chance to do is measure the neck wall thickness. Of the 100 peices of brass I measured 20. They ranged from 0.01275 and 0.01375 with an average thickness around 0.01375. I'm told that manufacturers try to create brass at an average thickness of 0.014 so these are a little thin to be neck turning. Other lots may very.
