In the Canadian Tire store I think you will find Remington Core Loct, not the premium, just the "ordinary," among the lowest priced of any ammunition. Get 180 grain and it will be perfectly suitable for moose.
Like someone said, bore sight it. Take the bolt out and get the rifle rested so it is pointing at the 100 yard range. Line the barrel up on something, then adjust ths scope to what the rifle is pointed at.
Then put up a target at 25 yards and very carefully, fire one shot at it's centre. Adjust the scope, so the rifle hits right on, or maybe ½ inch low, at 25 yards.
Check it at 100, with the object of of having it hit about 2 to 3 inches high at 100.
Go and get some moose meat. As they always say, one in the ribs is all you need. True, but most of us can't wait the 30 to 45 seconds it takes for him to fall over, so we put another one in the ribs. Or, the second may go to the head, if a it is in the clear.
