I think their is a huge percentage of hunters andtarget shooters who shoot traditional calibers....'06, 308, 270, 243 etc. that are very very happy with Sierra bullets and the support they receive from the tech staff. I have had limited success with the bonded bullets, Nosler being the happy exception. However, I am a deer hunter and have no use for a bonded bullet. The Pro Hunters, Game Kings and Nosler BT's get the job done for me year in and year out. The long bullets cause more problems that I am willing to deal with.....barrel twist, OAL and magazine lenght to name but a few. Good luck with your bonded bullets and regards, Rick.
