I don't use it for practice or anything but when I'm out in the bush I make sure it's in there. I have taken a few brown bears with it and wouldn't want anything else in the chamber for an animal that large.When it comes to "heavy/hot" ammo, whether it's in a long gun or handgun, I will use it but not on a regular basis. Settle on what you want for a particular hunt/situation, make sure it cycles and hits ok, then use it for that occasion. Sort of like defensive ammo, you make sure it functions without issue but you don't use it all the time for practice.
Amen to that. The OP specified PA blackbears. I stand by my previous comment and would hunt them with any factory offering my rifle shot well.I don't think id feel comfortable coming across a grizzly here in the bush with a factory load.
