I must admit having the best scope and best gun and good ammo doesnt mean a hill of beans if you cant shoot. i have a 1000 yard gun with a leupold on it shooting 1/4 groups at 100 yards and a2000 yard gun shooting 1/4 also with leupold . but i have killed deer at 450+ with my sons BSA on my 7 mag because my scope was broke so........... just had to say that
