No worries on the photo size.

As for the groups, good groups come with time and familiarity with the weapon. My first few groups with most any new rifle I buy or get in for review usually print around 1.5 to 2" if I jump on the gun cold (meaning not shooting anything else first to settle myself down). Once I get myself settled in and get a little more acquainted with that particular gun the groups start to tighten up.
