Hi All. Tried 3 different factory ammo in my 6.5x55. Norma 120g ballistic tip, Prvi Partizan 140g soft points and Federal Fusion 140g. The federals group superbly and I can pretty much clover leaf my groups. However after firing the primers on the federals protrude from the case head which doesn't happen with the Normas or the Prvi Partizans.
My guess is that Federal load is not generating enough pressure for the primer to be reseated after firing. Is this correct or is there a headspace issue with the federal cartridge? I want to reload the federal brass but have heard it is generally softer. Has anyone had any issue with reloading federal brass. Any advise would be appreciated. Thanks.
