Glad it worked out for you Mike, but I have a number of friends in the last few years that the scars to prove the bear intended harm; one went off a 50' cliff in front of his wife with the bear attached to him by the teeth, one was being shaken like a rag when the father's rounds finally scared the bear off. Neither situation was a sow/cub situation, both were bears being aggressive. There are more, but I don't want to belabor the point.
378 Weatherby- my rifle coach had one. First shot he said was the only time he ever got 'scoped' from a rifle. Second shot he said hurt, third shot he caught the scope as it was flying over his shoulder after the shot. Sheared the mounting screws. He had the gunsmith over size the next set of screws.
My good friend shoots a 300 Weatherby. I shot it once, that was enough. A powerhouse for sure, to the game and your shoulder. I can put a bullet where I need with my 06. Accuracy for me is better than volume of lead. Good bullets also.
Isn't it great we have so many choices!! Heck, I even have a case of 556 waiting for me at the store to pick up tomorrow... 1,000 rounds. Who wants to go shooting?
