I’ve sorted thousands of rounds of Lapua Center-X with the Neco gauge. The gun used is a 40X with one of Lee’s lightweight tuners. I found groups shooting sorted ammo had fewer fliers than the same lot of un-sorted ammo. While I didn’t record the data, I did see it on the targets. The plan this season is to record the results and determine if the gun has a preference for specific rim to ogive lengths.
The current lot shows less extreme spread in lengths than other lots I’ve sorted.
The pic below shows the frequency of lengths- 100 rounds were sorted. (in about 15 minutes).
