ar10 .260 - 01/03/17
I picked up a very nice dpms ar10 lite hunter in .260 a couple weeks ago . I have .243 and .308 brass on hand at this time , what do you guys do to make both of these into good reliable .260 brass ? I`ve tried after reading some very informative articles on sizing up the .243 . and sizing down the .308 . Any tips or techniques that you are willing to share with me would be great .Gary
