I've used them on coyotes and several other varmint bullets, Listen to me.... There is ONE 6mm bullet I can absolutely without question say through experience that is fur friendly and that is the 55gr Sierra Blitz kings. They are fantastic and never exit. There may be other bullets that do this, but I have not found it. I've tried all the Vmaxs (58,65,75, and 87) the SBK is way better. Tried Nosler 55gr BT, no good. The only other one is recommend to try is the 55gr Nosler Varmageddon's. HP or BT, I haven't tried them, but they shoot very well out of my TC Venture.
