[QUOTE="Chase723, post: 1656120, member: 21524"] This is good advice. I as well have relegated myself to the fact that the first 100 or so rounds will get my load close and get me familiar with the rifle. After that, once it settles down, it seems like every cartridge/bullet has an optimal pressure/velocity node and if you have a good consistent barrel, once you’re in the node, you should have really consistent velocities. I just accept it now and don’t get frustrated. If your other loads are around an ES of 10 my presumption is that your reloading practices are very sound. Switch to H1000 or Retumbo and I think you’ll be happy. Another thing, if you think your chrono isn’t reliable, just take it out as far as you can and look at your vertical dispersion. If it shoots 1/2 MOA at 100 and your ES is less than 15 then at 500 it should shoot ~ 2.5-3” Group. If your ES is >30 it’ll probably be >4”. If there’s no wind and you trust your shooting capabilities then you should trust that info. If you can push it out to 700, then your group should be <5”. If it’s >7-8” Then your ES is likely >30.
