What type of rifle do you shoot? From the 100 grain bullets you talked about, I'm guessing a .243 Win? If you were shooting a slightly beefier rifle, I would say the rifle. The accuracy is better and that makes a difference, even at short range. Plus, you can't beat the hydrostatic shock imparted by a high powered rifle. Shot placement is everything, but a bullet mushrooming in the lungs and heart at 3000fps sure knocks their socks off.
