Brass Case • FMJ
Solved from this product's advertised 3270 fps, 55gr bullet and G1 BC 0.267, 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 Lake City 55-grain M193 for target and range use. It fires a 55-grain full metal jacket bullet, the plain jacketed bullet most practice ammunition uses, at 3,270 fps, with 1,306 ft-lbs of energy at the muzzle. Load it only in rifles chambered for 5.56 NATO.
Compared with PMC's X-Tac 55-grain M193, the Winchester is a twin at the muzzle: both leave at 3,270 fps with 1,306 ft-lbs and kick the same in the same rifle, so either can stand in for the other. Compared with GGG's 55-grain M193, the Winchester starts 60 fps slower, and the GGG kicks about 2 percent harder in the same rifle, a gap most shooters will not feel. Only the GGG starts faster than the Winchester and the PMC, and neither gap is large.
Buy the Winchester for zeroing, drills and plinking with a fast 55-grain bullet from a maker that lists the load for that job. PMC's X-Tac 55-grain M193 is an equal choice at the muzzle. Pick GGG's 55-grain M193 if you want 60 fps more at the muzzle and don't mind a little more recoil. Pick ATS's 55-grain M193 if you want softer recoil and can give up 120 fps at the muzzle; it kicks about 4 percent less in the same rifle.
- Carries 96 ft-lbs more muzzle energy than ATS's 55-grain M193
- Kicks about 2 percent less than GGG's 55-grain M193 in the same rifle
- Matches PMC's X-Tac 55-grain M193 in muzzle speed and recoil, so either can stand in for the other
- GGG's 55-grain M193 starts faster, at 3,330 fps against 3,270
- Kicks about 4 percent more than ATS's 55-grain M193 in the same rifle
- GGG's 55-grain M193 carries 1,354 ft-lbs at the muzzle against 1,306
