Fifty yards is the most versatile line at the range: far enough that small angular errors show, close enough that conditions barely matter. It's the classic rimfire zero, the standard starting point for carbines, and a gentler proxy for 100 than the 25-yard line. Print the right target and it's also one of the fastest sight-ins there is.
For a .22 doing plinking or small-game duty, 50 yards is the standard final zero — close to the far crossing of most rimfire trajectories and the distance most rimfire targets get shot at. Zero here, know your holds inside and beyond, done.
With many common carbine loads, a bullet zeroed at 50 climbs only modestly above the line of sight and comes back through it far downrange — which is why "50/200" is shorthand at every range. The result is a flat practical hold over the distances a carbine actually gets used. The exact far crossing rides on your load and sight height; the app's solver shows your actual arc rather than the folklore version. Related reading: the 36-yard zero, its main rival for carbines.
A 50-yard group is a fine rough-in for a rifle that will live at 100 and beyond — offsets are half the size they'd be at 25, so errors multiply less. Rough-in at 50, finish and confirm at 100.
