Here is the only info we can go off that isn't rumor "The addition of Berger Bullets to Nammo unifies four brands that all share one common goal, which is producing the ultimate in precision performance. The four brands will continue to operate as unique brands servicing precision rifle shooters, while working together to enhance their collective offerings and services".
And the 4 brands are......"Berger Bullets joins an existing family of premium Nammo commercial ammunition components and ammunitions brands – SK, Vihtavuori and Lapua."
Eric Stecker, President of Berger Bullets said, “Supported by Nammo, Berger will continue to produce the highest quality rifle bullets in the world. Written words fail to describe how excited we are about the future of Berger Bullets and the growth of the other premium Nammo brands within the US market.”
So based on the other companies I would say we see no change but maybe more resources to expand.
