Hi everybody, I'm new here so I hope I can figure this out. I loaded 4 rounds .223 with 55gr fmj. that I got laying around and 4 grs. blue dot powder. It was really quiet and all four rounds made it out the barrel! But, 5 inch group and two landed sideways at 50 yards. I shot them out of a Ruger 77vt 26 in. barrel with a 1 in 12? twist, if I remember right. Any thoughts? Different powder, more powder, different bullet? Any help in tuning this load would be great.
