I have a 1962 Kodiak Magnum that I also draw to about 30 inches...we weighed it with an accurate scale and it was pretty much right on the marked weight of 45 pounds at 28 inches and a full 55 pounds at 30 inches...that is what is called stacking, a gain of about 5 pounds per inch...my guess would be you are shooting that bow at about 65 pounds...the truth is the Kodiak Magnum was never meant to shoot at 30 inches, unlike many of the 60 inch Bears...if you want to get an education on force draw curves check out peteward.com...Pete usually only weighs the bows to 28 inches since his draw length is 27 but sometimes he will take one, like the Covert Hunter, right out to 30
