Several years ago I came into possession of a 3lb peanut butter container of ,I believe, 30 cal cast bullets cast from a lyman 180 grain flat point gas check mould. I have put Lee's alox bullet lube and the Hornady .30 cal gas checks on 50 bullets. I weighed about 5 and they ranged between 172.2 to 183. something. I want to load some up for use in my 30.06. Should I weigh up several and group them according to weight then load? Any ideas will help. Thanks, Rod.
