70 is not big and I dont want to go down in the 60s myself. Look at the Sire of the bull and look at him. It is not so much the weight as it is how they are made. A longer leaner calf is easy to have vs. a chunk. Take his Reg. number and go to the angus site and look him up. You can trace him back on there to see what the other EPDs are on other generations.
