Managed to get a few rounds in today as well.
Talk about a disparity between groups. Shot my factory 6.5 CM barrel that I was bitching about the copper fouling in today. Just one box of factory 140 ELD-M so I could use it up. It averaged ~2/3 MOA for 4x5 when I shot it last year with the same ammo...but was wearing a Hellfire brake then. I left the end of the barrel bare today.
Two shots to get a rough zero, and then the next 5 went into .4". I was pretty stoked, so I brought out the chronograph as I was letting the barrel cool. Next group of 5 went into damn near MOA
with an ES of 90! But it had one round that read 77 FPS high, so I loaded my last 8 and shot the group on the left. Look at that badass ES and SD.
Looked at what i wrote on the box of factory 140 ELD-M that I shot a year ago...2,671 FPS, ES - 102, SD - 44.
LOL, no wonder the Hornady guys don't trust small sample sizes. They're shooting their own stuff.
I think there is some potential here for loads that weren't constructed by Hellen Keller.
