You have some lapua nm cases on hand? Mind giving a load neck diameter? Thanks
 
We have a small supply of samples on hand right now, and should be getting our first production run in before too long. Can't say exactly when, but it shouldn't be too long.
 
Alex, based on a small sample I have here at my desk, both calibers are running right at .015". The 338 seems to be a bit smaller, running .0145"-.0150". First run, but they should all be right in this ballpark.

Measured some Norma brand 338 Norma brass that I just received from the Bullets.com sale. Neck thickness was between 0.013" - 0.014" on all of them that I measured. None were over 0.014" and most were 0.0135". Guess I need to keep an eye on the neck measurement of the no-turn reamer used to cut my chamber?
 
Any updates on the 338 Norma brass availability from Lapua? Custom reamer is done and the barrel is chambered, now just waiting on BRASS & custom dies.
