Shooting my 22 Creedmoor today in the hot NV desert. I was experiencing terrible, mysterious groups (Oblong holes) and missing shots at 100 yards, but only with Sierra 77gr TMK bullets. Hornady 62-grain ELD-VT bullets shot well. The 85.5gr Bergers did okay. I fireformed some 53gr V-max (22/250) they did fair, but made it to kick up dirt at 300yds.
I never had this problem in the wintertime with these bullets? 8"twist 3,425 FPS. I just bored-scoped the BBL; it needs cleaning, but the Carbon ring was minimal. I was worried that my BBL was shot.
