I would like this to be a disscusion about bullet construction not caliber to use. For bear (GRIZ) not black which bullet would be best to use for both hunting 50 yards to 250 yard. And what bullet for protection lets say inside 50 yards. The NP, TBBC,A-Frame, or TSX. Let use the 300 WM as the caliber. Please tell me why for your choice such as penetration expansion etc. and feel free to add a bullet if you can think of another that may be better for the job at hand. Sorry to be so long winded but wanted to be understood.
