400 grain Speer with a schitload of IMR 4064 with a velocity (that is how fast the bullet is leaving the muzzle) of 2500 fps (FPS is Feet Per Second,that is how bullet speed is measured with firearms.) Forgot the primer,it is a CCI 250 Mag (CCI is Cascades Cartridge Inc.) The bullet is .458" which refers to bullet diameter in tens,hundreds and thousandths of an inch. Schitload refers to the powder charge in not to precise measurement.
