I was shooting in a friends rifle for him and developing some handloads to use this season and I noticed something I never experienced with my rifles. The point of impact between 25, 50 and 100 yards was different and by several inches. The gun has see-through scope mounts and the scope sits pretty high off the barrel. Has anyone else experienced this before. My rifles are bolt guns and my scopes are pretty flush with the barrel so I don't think it effects them as much. Thanks.
