Can a 1200 fps pellet gun kill a deer?

Answer 1

It is possible, but, highly unlikely as it would either require miraculous shot placement or a rifle and pellet with very specific, high end ballistic capabilities. Most larger caliber pellets that are used for hunting large game in some areas have a muzzle velocity in the range of 650-1000fps. Pretty much all pellets at 1200 will be unstable at range because the drop from supersonic speeds will destabilize it. Any pellets that you can get in the 1400fps+ range are likely to be .177 and not have the power or wound channel to drop an adult deer save a freak lucky shot.
