As a starting point I bought 100 Norma Jaktmatch ammo. After reloading them 2/3 times I already have at least 10 cases with split necks. I reload with the help from a friend along standard values.
We use the Vihtavuori book and the Ramshot website. I use Ramshot hunter powder and HDY 75 and 87 grain bullets. Using medium loads. Never approached the max loads as published on the Ramshot website.
My friend reloads for about 20 years along standard values published by the companies. No experiments.
Is the quality of Norma brass not as good as I thought ?
