Geeman,
The outfit I worked for always suggested .30 caliber and it makes sense when you have seen the ability to soak up lead some bears possess. Since you are a non resident for the state of AK you will be required to have a guide with you in your pursuit of a brown bear. He will have an adequate "stopper" caliber so your choice of a .300 win. or a .300 Wby. seems like a very good choice, both good general purpose rounds with lots of useful apps due to the great availability of various weight .30 caliber bullets. Have a great hunt practice with your .300 whatever flavor and you and your guide will prolly both be very happy with your choice. 1ak
