I bought a variety of ammo to shoot through my wife's new 270win. The Winchester 130g ballistic silvertip by far shot the best groups , right under 1 MOA. I was pretty happy until I started reading online the horror stories. People were complaining of no exit holes and the bullet not holding together after impact. most of these reviews seemed to be 4 or 5 years old. Anyone have any experience with these or ballistic tips in general? Will be used on WT
