Zak: I just purchased a Remington 700 5R Milspec. Would you consider this a premium/custom barrel needing very little or no break in? I read your response on a past post where you answer one of several questions including break in. I wanted to see which category my barrel falls in. I have shot one box of Federal Premium 308 168 gr Sierra MatchKing BTHP. I cleaned after every shot for 5 shots and cleaned after every three shots for the next 15 rounds. I wish I would have seen this GATE forum before I went to the range. Thanks.
