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 lists its White Box 55-grain M193 for target and range use, and it is a plain practice load for zeroing, drills and plinking. It carries a 55-grain full metal jacket bullet, the plain jacketed bullet most range ammunition uses, and leaves the muzzle at 3,180 fps with 1,235 ft-lbs of energy. Fire it only in rifles chambered for 5.56 NATO.
Compared with PMC's X-Tac 55-grain M193, the White Box leaves the muzzle 90 fps slower and kicks about 3 percent less in the same rifle. Both gaps are small; over a day of drills, few shooters would feel the recoil difference. Compared with GGG's 55-grain M193, the gap is wider: the GGG leaves the muzzle at 3,330 fps, 150 fps ahead of the White Box, and kicks about 6 percent harder in the same rifle.
Buy the White Box for zeroing, drills and plinking with a 55-grain bullet at a moderate muzzle speed. Pick PMC's X-Tac 55-grain M193 or GGG's 55-grain M193 if you want more speed at the muzzle and don't mind a little more recoil. Pick ATS's 55-grain M193 if you want slightly softer recoil; it kicks about 1 percent less than the White Box in the same rifle and leaves the muzzle 30 fps slower.
- Kicks about 5 percent less than GGG's 55-grain M193 in the same rifle
- Carries 25 ft-lbs more muzzle energy than ATS's 55-grain M193, 1,235 against 1,210
- Kicks about 3 percent less than PMC's X-Tac 55-grain M193 in the same rifle
- GGG's 55-grain M193 carries 1,354 ft-lbs at the muzzle against 1,235
- PMC's X-Tac 55-grain M193 starts faster, at 3,270 fps against 3,180
- Kicks about 1 percent more than ATS's 55-grain M193 in the same rifle
