I was going to suggest the OP send you a PM , you beat me to it . Also really good advice . I used to guide in Alberta before the earth's crust cooled , I used to give the same advice . Do your research , use a reputable outfitter and take a rifle you're familiar with . I remember being filled with dread when a client used to show up with a brand new rifle chambered in a hard kicking , magnum cartridge , they usually couldn't shoot them very well . Mule deer aren't hard to kill , any cartridge suitable for UK deer will work perfectly , the same applies to Black Bear . Most outfitters , including myself and all the guys I worked for , will have a rifle for you to use . I always had a bolt action 30/06 and a 270 ( for the guys who were scared sh*tless of their brand new hard kicking magnums ) available just in case of mechanical failures , scopes mostly . We never charged for use of the rifle , that may have changed however . If you do decide to bring your own rifle , an overseas hunt is a great reason to buy a new rifle by the way lol , it's fairly simple to bring it into Canada . You can go on the Government of Canada's website and it will show you what you need to do , it's very straight forward . BC is a beautiful place and has great hunting opportunities , you will have a great time . Post some pics of your hunt when you do it .
Good luck , AB
