Assumes the Hunting Primer. New here? Start there first.

Your objective

By the end, you'll be able to read a drop chart for your load and explain how much holdover or dial adjustment a .22-250 or rimfire requires at 100, 200, and 300 yards.

Concept ~8 min

You zero your .22-250 at 100 yards, then settle onto a groundhog at 275 yards. If you hold exactly where the reticle sits, where does the bullet go? Not into the animal — the arc of gravity has already sent it several inches low. Knowing your load’s drop chart before you pull the trigger is the difference between a clean hit and a frustrated miss.

Quick recall

From the previous lesson — when you pre-range landmarks before a hunt, what two things does that practice give you when a groundhog appears?

How gravity shapes every shot

A bullet leaves the muzzle traveling nearly horizontally. From that instant, gravity pulls it downward at 32 feet per second squared. The scope sits above the bore — you zero the rifle by angling the barrel slightly upward so the bullet’s arc crosses the sight line at your chosen zero distance. Past that zero the bullet keeps arcing down, and the drop accelerates.

Drop is not optional. Even the flattest-shooting rifle in your varmint bag is dropping inches at field distances. The only question is how many inches, and how to compensate.

The why Why bullet drop accelerates at distance

Drop is proportional to time of flight squared. At 100 yards a fast bullet might be in flight for 0.1 seconds; at 300 yards it’s been flying roughly 0.3 seconds. Gravity acts on every fraction of that flight time. Double the time of flight and you get four times the drop — which is why the numbers on a drop chart grow so much faster than the distances do.

The flat-shooter: .22-250 drop at common distances

The .22-250 is considered a varmint rifle precisely because its combination of high velocity (55-grain bullet at roughly 3,600–3,700 fps) and decent ballistic coefficient keeps the trajectory very flat to 200 yards.

Approximate drop for a .22-250 zeroed at 200 yards (55-grain load):

DistanceDrop from line of sight
100 yds+1.5 in (still rising to zero)
200 yds0 in (zero)
250 yds–2.5 in
300 yds–6 to –9 in

Those numbers vary with exact load, muzzle velocity, and elevation — which is exactly why you build your own chart. The table above is a working example, not a substitute for your specific rifle’s data.

Edge case What about a 100-yard zero on the .22-250?

With a 100-yard zero, the .22-250 is about –1.5 to –2 inches at 200 yards and –8 to –12 inches at 300 yards. A 200-yard zero gives you slightly more range before holdover is required — most .22-250 varmint hunters prefer the longer zero because of the flat 0–200-yard window it creates.

The rimfire reality: .22 LR drops hard

The .22 LR is a genuine hunting tool at close range, but its trajectory is dramatically different from a centerfire varmint round. A high-velocity load (CCI Stinger, 32 grain, ~1,640 fps) with a 50-yard zero:

Approximate drop for a high-velocity .22 LR zeroed at 50 yards:

DistanceDrop from line of sight
50 yds0 in (zero)
100 yds–2 in (high-velocity load)
150 yds–11 in
200 yds–30 in

A standard-velocity .22 LR (40 grain, ~1,100 fps) drops much more — around 7–12 inches at 100 yards and 54 inches at 200 yards. These numbers mean the .22 LR is a burrow-edge, inside-100-yards tool for varmint hunting. Using it at 200 yards without precise range and a specific holdover for that load produces misses or, worse, wounding hits.

Two ways to compensate: holdover and turret dial

Once you know the drop at your target’s distance, you have two correction methods:

Holdover: Place the reticle above the animal by the drop amount. If your .22-250 drops 7 inches at 300 yards, hold 7 inches above the aim point. This is fast but requires you to know the drop and judge that distance on the animal in the field.

Turret dial (elevation adjustment): Modern varmint scopes often have ¼-MOA or ⅛-MOA per click turrets. Dial the required elevation correction in and your reticle center is now your new point of impact. This is precise but takes more time — better used from a prepared stand than in a hurried shot.

Deep dive What is MOA and how many inches is one click?

MOA stands for minute of angle — it is an angular measurement. One MOA equals approximately 1.047 inches at 100 yards, rounded to 1 inch for practical purposes. At 200 yards, 1 MOA = 2 inches. At 300 yards, 1 MOA = 3 inches. A scope with ¼-MOA clicks moves point of impact ¼ inch at 100 yards per click, ½ inch at 200 yards, ¾ inch at 300 yards. To dial 7 inches of elevation at 300 yards: 7 ÷ 0.75 = about 9–10 clicks on a ¼-MOA scope.

Comparing the two trajectories

The diagram below plots a simplified comparison of a flat centerfire arc versus a steep rimfire arc from a common vantage point to a target at 300 yards. The labeled points show where each bullet’s path crosses key distances.

Read the chart

Knowledge check

A hunter's .22-250 is zeroed at 200 yards. The drop chart shows the bullet is 7 inches low at 300 yards. There's a groundhog at 300 yards. Which is the correct approach?

If you remember nothing else

  • Every bullet arcs — gravity pulls it down from the moment it leaves the barrel. A drop chart quantifies that arc for your specific load.
  • .22-250 stays nearly flat to 200 yards (roughly 1–2 inches low) but drops 6–9 inches by 300 yards — far from zero-and-forget.
  • .22 LR drops steeply: 7–12 inches at 100 yards and 30–55 inches at 200 yards depending on load. It is a short-range tool.
  • To correct for drop you can hold above the target (holdover), or dial elevation on the turret if your scope has repeatable clicks.
  • Build your own drop chart — the numbers above are examples. Your rifle, load, and zero will give different results.
