I bought my daughter a H&R Handi Rifle youth 223 and just took it to the range for the first time today. I shot several shots at 25 yards and got it so I was hitting about 2" high. I moved a target out to 100 yards (only able to shoot 25 & 100 yards at this range). I took 3 more shots and did not even touch the target (standard size target). I did not have time or larger targets to try to find out where i has hitting. Im shooting 55gr bullets. Any idea if the bullets are hitting high? Also why would it be that far off between 25 and 100 yards?
