A couple friends and I were out yesterday getting a our rifles ready for the vintage bolt gun match next month and we ran into some trouble. Two of us were shooting 6.5 swedish mausers and 140 gr. nosler custom comp. bullets and we both experienced the bullets breaking apart. We weren't pushing them over 2600 fps and we didn't have any troubles with lapua, sierra, or hornady bullets driven by the same powder charges. Has anyone else had trouble with these bullets?
