Did you notice much differnce in the ballistics ? I have a NEF .243 bull that shoots real well. My 14 year olddaughter can shoot an 1 in. group at 50 yards and does not even get a cheek well on the stock. Back to the 30-30 I witnessed a 172 in. buck get shot open sights at or about 100 yards and dropped like his life fell out of him. Very impressed with that and guy didnt even mount it what a waste of a great buck. He has several antlers lying in his shop around 150.
