Go buy a box or 2 of commercial ammo, run it over your chrony and look at the extreme spread. Surprise? Or watch Paul Harrel's (?) attempt to show longer barrel has higher fps. Several brands of good 223 stuff and he calls out chrony numbers - 50 fps min ES! Yup, he proved difference was about 200 fps. Yes, handloaders can trickle loads to reduce but does the average guy do that? I don't, I don't often shoot > 100 yds. Nothing against money shooters, I'm not one and probably most here aren't - but a few here seem to want to dictate real world physics. I shot my new Long Ranger 308W a while back, as much a pencil barrel as anything, pretty fast and still had a good group @ 100. 4 shots 50 yds Amax load, 0.5 MOA. 5 shots @100, ES 1.01 MOA, SD 0.29 MOA. Good enough for hunting. My communication better?

Am I missing something here? Since when are ES and SD part of measuring group sizes?
