if you shoot a 180 grain Federal Nosler Partition for deer and then switch over to 180 grain Trophy bonded bear claw by federal for elk chances are you will not have to touch the scope. every rifle is different

My 308 shoots all different types of bullets the same...Just try them out. I am not sure one bullet fits all works the best but it can be done......people killed ELK and deer long before the supermagnum existed
