Maximum effective range is generally accepted to be 1,210 yards (1,110m) with ammunition incorporating low-drag projectiles. More mid-range rise can be accepted when hunting larger animals (a 4 inch MRT might be appropriate when hunting mule deer, for example), but if a mixed bag hunt for larger and smaller species is envisioned, then the 3 inch rise used for this table is probably safer.

Also, many rifles available today now have effective recoil attenuating features built into them, such as muzzle compensators and energy absorbing stocks and butt-pads, that can significantly lessen recoil as it is felt by the shooter. Thus between the muzzle and the distance given as the MPBR, the bullet never strays more than 3 inches above or below the line of sight (1.5 inches for varmint loads). loading brass has a wide variety of options ranging from 130 up to 210 grain bullets such as Scirocco, If Winchester had released the cartridge prior to 1960, the cartridge would have been similar to the .30-338 Winchester wildcat cartridge.

This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 220 gr (14.26 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 2,850ft/s plus or minus 50ft/s (869m/s 15.2m/s). The 165 grain bullet provides a higher ballistic coefficient than similarly shaped 150 grain bullet while maintaining a very high velocity which is translated into a flatter trajectory. Web300 Win Mag 178 gr ELD-X Precision Hunter . The SAAMI Maximum Average Pressure (MAP) for this cartridge is 441.3MPa (64,000psi) piezo pressure (54,000 CUP). One way to think about this is as such: a foot-pound is a unit of energy equal to the amount of energy required to raise a weight of one pound a distance of one foot. The maximum point blank range for the 9.7g (150gr) bullet is 291 metres (318yd) yards when zeroed at 250 metres (270yd). Recoil from the .300 Win Mag is noticeably higher than the well-known and popular .30-06 Springfield.
