That is a maximum load; very few find the maximum loads to be the best for their rifle or hunting conditions. Personally I shoot elk at 100 to150 yards and with 300gr. bullets find about 90gr. of powder to be plenty. I also agree that taking what the scope says and relying on that without a lot of shooting is a good way to miss your deer. Find a load that shoots well in your rifle and then check the ranges if you want to use the range marks on the scope. Or just use the 3" over rule which is also pretty fair for most conditions. Personally I like to know that my rifle is dead on at any of the distances that I plan to shoot and with the extra stress of the hunting condition I can still be in the kill zone even though the accuracy is not like what I get on the bench.
