Daryl S,
The most dramatic performance I've had with a particular bullet is the Trophy Bonded Bear Claw. I've used them in everything from 338 Win Mag to 375 H&H to 458 Win Mag on deer (Sitka blacktail) & bear (black & brown). A 225 gr TBBC out of a 338 WinMag dropped a 9 foot brown bear on the spot. The 300 gr in 375 is potent stuff also. These are tough bullets. I pretty much swear by 'em.
