Hi all,which primers do you use for cast boolit loads in(mostly).30cal. milsurps and why?Large rifle or Large pistol? I also have converted some Berdan brass to use 209s.Personally I,ve not noticed any bolt face cratering due to my reloads leaking gas past the primers but I do have an old 98/06 sporter which has some cratering which ,to be honest,I didn,t see when buying it and I,ve only shot low pressure loads through.Your input,as always,will be much appreciated.Cheers,Mike.
