You will be fine with which ever load you decide on, btw, that is a beautiful rifle.I'm worried about them not expanding properly on a black bear. To my understanding on the 9.3s the partition was moved forward to improve performance on large game like cape buffalo. I'm sure they were designed to be used in the faster 9.3x62 and 9.3x64. The minimum recommended velocity is 1800 fps, so I'm well above that. But with my 9.3x57 I'm giving up 200-300 fps over the x62. The close range should offset that to some degree. Just looking for real world experience.
