I'm considering a new barrel for my ruger m77 mkii that is currently a 270 win. What would be an all around good caliber for deer elk and moose. I don't go elk or moose hunting much but will go a few times this rifle would be more for deer but will get used on elk and moose sometime. If I could justify a rifle for the bigger animals i would just go with a 338. I don't want to blow the beep out of my deer.
