For deer-sized game across North America, 243 Winchester hunting ammo loaded with bonded soft points offers a balance of flat trajectory and controlled terminal performance. The Norma American PH line delivers this balance with a 100 grain Oryx jacketed soft point — a bullet designed by Norma to mushroom predictably across a range of impact velocities while retaining core weight through bone and muscle. At 2990 fps muzzle velocity and 1986 ft-lbs of energy, this load sits in the middle of the 243 Winchester performance envelope: enough velocity for reach, enough bullet mass for penetration on broadside shots through the vitals of whitetail, mule deer, pronghorn, and similar-sized game.
Built for the Box
The Oryx bullet uses a thin forward jacket with internal splitting zones to initiate expansion on impact, while a thicker rear jacket and bonded core prevent premature separation. Norma’s bonding process fuses core to jacket before final assembly, so the bullet stays together as it penetrates hide, muscle, and bone. Sectional density of 0.242 is moderate for caliber — suitable for typical broadside lung shots at ranges where retained velocity keeps expansion consistent. Brass cases carry Boxer primers and are reloadable for handloaders who want to work up custom loads after confirming zero with factory ammunition.

This load fits within the 243 Winchester SAAMI spec and chambers in bolt-action and semi-automatic rifles with a 1:10 or faster twist. Confirm zero at 100 yards before hunting — bonded bullets may print to a different point of impact than cup-and-core loads of the same weight.
