I have only had a 10/22 mag for a month now. I have noticed that when I am shooting cci and super x hollows my groups are nearly a half inch smaller at 100 yds. compared to what they are at 50 yds. I am not complaining believe me. I am just wondering if this is normal. I had been contemplating a .17 barrel but I think I will just leave it alone. I do believe this bad boy can do everything I need of it out to 130 yds.
