Simple Range Estimation Technique

You do need to know this skill, even for your SPOT/SALUTE reports.

Practice now while the range is still one-way.

  1. The assumption being with the naked eye and no magnification? If so, I missed that.

    • Guess I missed it too. He makes reference to the technique so that the shooter does not have take his eyes off the optics. I assumed a 1x dialled in for the range, magnification for the shot.

    • You are correct.

    • He said it at about 2:14.

      • @singlestack is correct, I was caught up in Shrek’s imagery in my mind’s eye and missed it. Homework assignment; leaving the house now (on foot with my ruck, of course, on a stroll to the beach) to dope my own cataract corrected eyeballs using my laser rangefinder and his visual references. I love this blog!!!

        • And this is the most important part of the technique. Not everyone has the same eyesight so the actual ranges vs visual cues have to be calibrated to each individual. A slightly more universal technique is the football field technique where one guestimates the number of football field lengths between the observer and the target. Both require experience and practice of course.

      See vid at ~2:11-2:15 when he mentions this technique is for the “naked eye.”

  2. Anyone starting to see how brainwashed the typical ‘soldier’ is?

    They loves them some stars n stripes.

    Right or WRONG

    • Your weak ass looks like the 600 meter visual at 2 meters.
      As usual you have nothing constructive to contribute can not wait till 20 Jan, and Trump cuts yo SNAP benefits off.

      • When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another…

        …That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security….

        …He has refused his Assent to Laws, the most wholesome and necessary for the public good.

        He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.

        He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.

        He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their Public Records, for the sole purpose of fatiguing them into compliance with his measures.

        He has dissolved Representative Houses repeatedly, for opposing with manly firmness of his invasions on the rights of the people.

        He has refused for a long time, after such dissolutions, to cause others to be elected, whereby the Legislative Powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.

        He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.

        He has obstructed the Administration of Justice by refusing his Assent to Laws for establishing Judiciary Powers.

        He has made Judges dependent on his Will alone for the tenure of their offices, and the amount and payment of their salaries.

        He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people and eat out their substance.

        He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.

        He has affected to render the Military independent of and superior to the Civil Power.

        He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:

        For quartering large bodies of armed troops among us:

        For protecting them, by a mock Trial from punishment for any Murders which they should commit on the Inhabitants of these States:

        For cutting off our Trade with all parts of the world:

        For imposing Taxes on us without our Consent:

        For depriving us in many cases, of the benefit of Trial by Jury:

        For transporting us beyond Seas to be tried for pretended offences:

        For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies

        For taking away our Charters, abolishing our most valuable Laws and altering fundamentally the Forms of our Governments:

        For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.

        He has abdicated Government here, by declaring us out of his Protection and waging War against us.

        He has plundered our seas, ravaged our coasts, burnt our towns, and destroyed the lives of our people.

        He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation, and tyranny, already begun with circumstances of Cruelty & Perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.

        He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions….

        fucking flag wavers…

        100-200 million is a good number.

    • In the time you’ve been commenting on this site you’ve made your disdain for America quite clear. So why are you here?

  3. A typical 556 iron sighted in at 200 yards is a neck hold at 300 yards for a center of mass hit. A target at 400 yards a hold just above the head is needed and iron sights obscure the target. At 500 plus yards wind begins to have significant impact on holds, and holdovers are difficult without reticle references or background references such as a berm with discernible features. A range adjustable rear peep can deal with holdover consistency at extended ranges without obscuring target or needing reticle or background reference points. More importantly the danger space at 500 plus yards becomes a narrow distance tolerance that may overwhelm the resolution of the crude range method here. At 400 yards the danger space is 285-460 yards allowing for at least a 15% error in ranging. At 500 yards danger space collapses to about +\- 50 yards and at 600 yards about +\- 40 yards. Thus the ranging method presented here isn’t really needed out to 400 yards and beyond that this method’s accuracy doesn’t resolve within the danger space reality of target size and bullet trajectory.

    It’s a good method in the absence of anything else but the first round hit probability for unknown targets ranges beyond 500 yards is probably 50% or less. If you can’t discern a head (400+ yards) a good tactic with no rear sight elevation adjustment is a 3 round bracket volley. First shot hold center, re acquire sight and just obscure top of target with front sight post for second shot, and finally hold above target for third shot. This technique follows recoil and with punctual shot timing the second or third shot will arrive on target before most conscious reaction time. However, beyond 400 yards if your caliber isn’t greater than 6 point something with some speed behind it, unless you are shooting at paper or steel you probably just fucked up.

    • SO if you can’t be certain of a quick KIA on the target, maintain concealment and wait for help, or get closer if you have a good E&E plan?
      Don’t stir up a hornets nest unless you can kill all the hornets.
      Makes sense to me.

    • Randall Flagg

      Or, in other words…. for anything past 200, just use 7.62 NATO and be done with it.

      • How about a 280 Ackley? I am having a new barrel put on my my 270.
        I want 1000 foot pounds at 1000 yards, for hunting feral pigs in the fields of South Georgia. I have my HBAR for lightweight stuff. Worked standing offhand at 50 yards with it today. What is a reasonable expectation of accuracy and what is the goal at say 50 and 100 yards? 75% in a 6 inch plate at 50 yards from a low ready on a beep ?
        6 inches at 100 yards snap shooting within two seconds?
        It was getting heavy after 30 rounds coming up from the waist.
        Time to train up.
        I may have to build a lightweight 18 inch rifle.

  4. Width Over Range = Meters

  5. Never looked like triangles to me at 600 yds. More like single upright grains of brown rice moving around.

    Reblogged this on FOR GOD AND COUNTRY.

  7. M4 front sight post is 7moa. If target torso matches the width he’s 21 divided by 7 away , in hundreds. … 300 yards , to match front sight width. That’s all I got with a naked eye … so it’s my system. Change the math for your Aimpoint s dot size if applicable.

  8. Cool knowledge and easy to practice in the urban environment (sans firearms of course). Parking lot striping is approximately 9 feet wide, so counting stripes and then practice seeing what a human being appears to be at that distance.

    Another trick – use your own hand to judge distance. Hold out your arm at full length, and compare the height of a known height against your thumbnail against object. For me, a 6 foot high object is 64 yards away from me. So half a thumbnail is approximately 128 yards. And so on. Our arm and nail lengths vary per individual, so check for your own ranges.

    Thanks for the link.
