Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!

Good grief, these people are such gaslighting assholes.

I wonder what he had to say after two Democratic state senators in Minnesota were murdered. And after Paul Pelosi was nearly murdered, for that matter.

Hey Jesse, did u know liburals can study really gud? Mostly becaus3 we believe in education.

A common long-range civilian setup: .338 Lapua Magnum, 250–300 gr (≈16–19 g) very-low-drag bullet, muzzle velocity ~850–900 m/s. Target distance: 2000 yd ≈ 1829 m.

What happens to the bullet

1) Drag (air resistance) does most of the work.

Drag scales roughly with the square of speed. The bullet leaves supersonic, slows hard at first, then even more as it nears the transonic region (~Mach 1.2→0.8). A .338 LM VLD bullet often goes subsonic before 2000 yd, which adds small, messy instabilities (buffet, increased yaw). Result: time of flight stretches to on the order of 3–4 s.

2) Gravity never clocks out.

While the bullet is covering the 1.8 km, gravity pulls it down continuously. With realistic drag, you’re looking at dozens of meters of drop by 2000 yd—think ~40–55 m (rough scale), not centimeters. That’s why long-range optics dial many tens of mrad/MOA.

3) Wind is a tyrant.

Sideways air matters because the bullet lives in the airstream, not on a chalkboard. For a steady 10 mph (≈4.5 m/s) full-value crosswind, lateral drift at 2000 yd is meters, not inches—roughly 5–15 m depending on exact bullet, density altitude, and how much of the flight is subsonic. A 1 mph error can easily shove you >0.5 m off at this range.

4) Spin drift (gyroscopic drift).

Right-hand twist barrels impart a subtle rightward drift as the bullet’s spinning axis processes in a gravity field. At 2000 yd this is commonly ~1–2 m to the right (order-of-magnitude).

5) Coriolis (Earth is rotating under you).

Over a ~3–4 s flight, the Coriolis deflection is modest but real—typically tens of centimeters up to ~0.5–1 m, depending on latitude and the firing azimuth (most noticeable shooting north/south; almost none due east/west at the equator).

6) Energy on target.

Muzzle energy for .338 LM is ~6–7 kJ. After 2000 yd the bullet’s speed may be ~250–350 m/s, giving ~500–1000 J remaining—still serious, but a small fraction of launch energy.

A compact worked picture (illustrative, not a firing table)

  • Cartridge/bullet: .338 LM, 250 gr (~16.2 g) VLD
  • Muzzle velocity: ~900 m/s
  • Time of flight to 2000 yd: ~3–4 s
  • Gravitational drop: on the order of 40–55 m by impact (drag-inclusive)
  • 10 mph crosswind drift: roughly 5–15 m
  • Spin drift (RH twist): ~1–2 m right
  • Coriolis: ~0.2–0.8 m scale, sign depends on azimuth/latitude
  • Impact speed/energy: ~250–350 m/s, ~0.5–1 kJ

Why 2000 yards is “edge-of-envelope” for typical civilian rigs

  • Transonic crossing: Many .338 LM loads go subsonic between ~1500–1800 yd. Crossing transonic erodes ballistic coefficient and can perturb stability.
  • Error growth: Tiny input errors—muzzle velocity spread, wind gradient with height, density altitude shifts—balloon into meters of miss distance.
  • Angular resolution: At 1829 m, 1 milliradian ≈ 1.83 m (1 MOA ≈ 0.53 m). Your scope’s clicks, your hold estimation, and your bullet dispersion have to play nice at that granularity.

The physics takeaway

A 2000-yard shot is a four-second argument between inertia and atmosphere, refereed by gravity and heckled by Earth’s rotation. The bullet’s story is written by drag (v²), gravity (g), and a stack of second-order effects (wind fields, spin drift, Coriolis, aerodynamic jump), all amplified by long time-of-flight. It’s not magic; it’s compounded small physics.

Just saying, with this type of unhinged rhetoric, liberals and minorities should exercise their 2A rights.

It's got the potential to get bad because guys don't need facts before they shoot especially with a influential guy here, and he is, actively encouraging his followers to avenge Kirk and blaming the left with no proof.
