Thread: The answer to my 223 ES pissing and moaning?

I'll stick my neck out, I don't think the issue is related to ES. Take the bottom right target as an example. The Sako factory load.... 10 shot group (6 recorded velocities that I can see) largish vertical dispersion but only 35 fps ES (I'm not gonna do the SD math).
Leave out the windage variation as you say there was variable wind, perhaps this is the limit of the setup?For a short, handy little rifle, call it good.
