i currently use winchester 180 gr. silvertips in my 30-06, and i saw the other day on thier website that the accubonds that winchester uses has a black coating, and its called Lubalox. i am wondering with this coating if there are any affecting factors to the gun barrel and rifeling if i was to use this ammo. also would i still have to use copper cleaner when i clean the gun even though there is some kind of coating on the bullet? anyone that has had any expierience with this ammo i would love to hear what your input is!! thanks
