[QUOTE="Dean2, post: 1677447, member: 26077"] The Chrongraph you are using could easily be causing as much variation as anything else. I use Shooting Chrony products but they are [B][I]extremely[/I][/B] sensitive to setup, light and shooting angle. Unless your shots are going across the Chrono at exactly the same angle and spot on the pickups with consistent light you can easily get 100 FPS variation in a load that should have an ES of 5. This is far more likely to be inducing high ES than your shooting style, given all the other quality and appropriate prep work you have done to get ES in line. If you have access try running some rounds through a Lab Radar and see what you get for ES without changing anything else. Other option is to test your Chronograph. Take some Eley Tenex ammo and shoot it across your Chrono. This is very high quality RF ammo and should show an ES of well under 10 FPS. If you are getting more than that it is the Chrono. [/QUOTE]
