Solved from this product's advertised 3180 fps, 55gr bullet and G1 BC 0.246, with the sight 1.5" over the bore at standard conditions. Compare every zero for 5.56x45mm NATO, or read Maximum Point Blank Range for 5.56 on an AR-15.
How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 8" vital zone, ±4" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 500 yards.

Product Overview
Winchester's White Box 55-grain M193 is a full metal jacket 5.56 NATO load made for recreational shooting. The bullet follows the military M193 pattern, a plain full metal jacket with a closed nose. It leaves the muzzle at 3,180 fps with 1,235 ft-lbs and has a G1 BC of .246.
Zeroed at 50 yards, it drops 10.5 inches at 300 and 26.9 inches at 400. With a 36-yard zero it drops 7.8 inches at 300. At 55 grains it is the lighter of the caliber's two NATO bullet weights, and recoil is light to match.
If you're cross-shopping, PMC's X-Tac 55-grain M193 starts 90 fps faster behind a boat-tailed bullet, and from a 50-yard zero it drops 25.0 inches at 400. GGG's 55-grain M193 is quicker again at 3,330 fps, worth 1,354 ft-lbs at the muzzle.
- Still moving at 2,093 fps at 300 yards
- A plain lead-core full metal jacket, not the green tip that some indoor ranges and steel-target bays refuse
- About 3 percent less recoil than PMC's X-Tac 55-grain M193 in the same rifle
- Loaded to 5.56 NATO pressure, so it is not for a rifle chambered only for .223 Remington
- GGG's 55-grain M193 starts 150 fps faster with 119 more ft-lbs at the muzzle
- Only ATS's 55-grain M193 starts with less muzzle energy among the loads it sits against
