I load .010 off the lands for my .308 and with the Hornady Match 168gr. I'm getting some finished round that are .008 longer (none shorter) that the rest. I'm attributing this to the fact that I changed from Sierra MatchKings. I rarely had more than .003 with them and never reset them, but I'm thinking I'll need to with some of these. My line of thought is that by doing so, I'll be setting them deeper than the others and pressures and velocity will be different than the rest. For future batches, I'll be setting the die to seat .005 deeper. That should eliminate any excessive length rounds while the increase in jump on the others will be minimal.
