Having successfully fired a selection of LEE cast boolits (92 gr. - 160 gr., PC'd and sized .311) through it, can anyone who KNOWS tell me what size jacketed bullets I might buy, as in .308 or .311/2??? Did Ruger make special bbls. or just use a run of .308s? Just being lazy and fearful of sticking a boolit in the bore trying to 'slug' it. Did that once and don't wish a repeat.
