ok i bought some arrows at gander mountain for my 40-50 lb bow. They are carbon tech 3050 which is 8.4 grains per inch. I mainly bought them just so i could get started shooting. They guy told me that they would not be strong enough to kill a deer. He said that when the arrow would hit a bone they would shatter. Is this true. If so how many grains per inch do i need? I would like to get the easton n-fused if i could but i dont know if the gpi will be right. I dint really understand all this stuff that much so i would appreciated it someone would explain it to me.
Thanks
