I recently picked up a new NOE mold 311-199-SP-K5 3 cavity. I've got some good one cast and about to do the sizing and gas checking.
I'm actually holding off as I may get a new sizer. My older sizer for the RCBS sizer lubricator is 0.308". I'm thinking I may go with a new sizer for the STAR sizer either 0.310" or 0.311".
Looking for suggestions...What are some of your thoughts on sizing these bullet for an AR 308 Win and other 30 cal rifles sized at 0.311".
I did make a DUMMY round with the unsized bullet (0.311") and it chambered fully and ejected without any difficulty.
