At SHOT Winchester was showing there new bonded Ranger line of ammunition. It is claimed that the new Bonded Ranger (RA9B & RA9BA) performs similarly to the standard Ranger RA9T & RA9TA. In Winchesters gel test they show slightly increased penetration, and reduced expansion but with the benefit of penetrating auto glass and bodies effectively out performing the standard Ranger line of ammunition in these situations.
Have there been any independent tests yet?
