LE,
what were the range conditions like? i see more vertical spread (higher ES/SD) than horizontal (wind). when I occasionally shoot with the f-classers at mid range, which for them is 600 yards, i get coached that what they want to see for inexperienced shooters (me) with handloads is a horizontal dispersion (water table?). If the ES/SD is low, like they recommend for long distance shooting, one will get less vertical dispersion at distance. L/R dispersion is due to my inexperience with reading and compensating for variable wind conditions. If i end up with L/R dispersion, I can get some wind coaching. If I have a lot of vertical, they tell me go back to the drawing board wrt my reloads. Large ES/SD really shows up at distance. These guys keep tweaking loads until their SDs are single digits. Like 5 or so. I'm not there yet. My SDs are not consistently in the single digits. once in a while. I still haven't pinpointed what is varying to give me SDs in the low teens more often. however there are a lot of variables to consider when working to get SDs in the single digits. And not only does it have to have low SD, it also has to group well. due to barrel harmonics and such the two conditions don't always arrive together.
Still, you shot the rig/ammo pretty well LE. Congrats. well done.
is that the F-Class mid range, with the 1/2 MOA X ring or is that the standard NRA high power iron sight X ring of 1 MOA ?
again, congrats!!
