there has been but ONE "bear rifle"- the model 71 WINCHESTER in 348- look at the performance of that, and if yours exceeds that, then it IS MORE THAN ADEQUATE for bears- sure, there are rifles that you CAN USE on bear, and that's where most of the rifles lie, but the 71 was BUILT FOR THE JOB- it's modern day offspring is the 338 win mag-NOT A 30 CALIBER ON SPEED- which is all a 30 cal magnum is- i don't care which one you like- they're ALL the same- sure , you've got more range and velocity, but you're still shoving a 30 caliber BULLET WEIGHT -but all this arguing is moot as the only places you're allowed to shoot GRIZZLIES IS B.C. AND UP NORTH- OR AK- in alberta, they just went PROTECTED- that means no shooting - unless self defense, and that means up close and personal- and that's 45/70 or 12 guage
