There is a religion regarding "Belted vs non-Belted". I can not say entirely that I haven´t spoked against belted cartridges at one time..however I have a nice .300 H&H M98 and a Ritterbusch .378WEA + a custom pre-64 rifle in .270Wea. They all Work to perfection!!. My.416Rigby(former), 333Jeffery, 8x57 Work perfectly well too.. All my rifles are controlfeeded.
If I didn´t have my Ritterbusch in .378WEa I wouldn´t have sold my .416Rigby to begin with. Should I Again have a .400bore bolt-repeter the .400 H&H would become a strong candidate.
