Has anyone had any problems with one of these?A friend of mine was one three different Shooters and two different scopes and best we could get is 12" or larger 3 shot groups with hand loads with 140gr berger hunting VLDs and us869 from 84 to 88gr.He sent it back to nosler and after a pretty good while they said it grouped there ammo in just a little over 3/4" soon as he gets it back he's going to try the reloads again.Thanks
