Winchester White Box 5.56mm 55gr M193 Ammo Bullet Drop and Load Data
Product Overview
Raw performance still matters - that's why Winchester's 55gr M193 remains a benchmark for 5.56mm ammunition. Each round exits the muzzle at an impressive 3180 fps, creating the kind of flat trajectory that makes holdovers nearly obsolete inside 200 yards. That velocity translates into 1235 ft-lbs of energy, enough to topple coyotes and drop prairie dogs like they've been struck by lightning. The standard 55-grain bullet weight means optimal stability in everything from pencil-profile barrels to heavy contour match tubes.
Field testing reveals why this load has earned its reputation. Those high initial velocities mean better terminal performance on varmints, while the FMJ construction cuts clean holes in paper that make scoring a breeze. During rapid-fire drills, you'll notice how the consistent pressure curve keeps your rifle cycling smoothly even when the barrel starts heating up. The projectile's standard weight profile also means minimal adjustment when transitioning between different shooting positions - a huge plus during competition.
Where this ammunition really stands out is in its ability to deliver consistent performance across high round counts. Those weekend classes that burn through 500 rounds? No problem. Monthly 3-gun matches? You're set. The economical pricing means you can actually afford to train regularly instead of hoarding your "good stuff" for special occasions. And unlike bargain-bin alternatives that leave your rifle dripping with copper fouling, these rounds keep your bore clean enough to pass inspection even after marathon range sessions. Think of it as investing in trigger time instead of just collecting brass.
Pros and Cons
Advantages
- Balanced velocity delivers reliable accuracy while minimizing wear, ideal for regular range practice
- Moderate pressure curve helps preserve extractor life during extended practice drills
- Produces less felt recoil than hotter loads, supporting faster target transitions during drills
- Works smoothly across different gas system lengths without requiring adjustments
Disadvantages
- Mid-range velocity requires additional compensation for wind drift compared to premium options
- Basic projectile design offers fewer advantages than specialized target or hunting loads
- Performance metrics fall in the middle of the pack, limiting maximum effective range
