minnesota1 Posted August 7, 2020 Share Posted August 7, 2020 I just picked up a Romeo5. I heard the 36 yd zero works best for smaller spread out to 300 yards. If you have a 36 yard zero does anyone know where the impact is at other ranges? Using 55gr FMJ. Standard 233 ammo I realize barrel length, Ammo etc makes a difference. I’m looking at what the general numbers people have come up with for the 36 yd zero. Thanks!! Link to comment Share on other sites More sharing options...
DesertTortoise Posted August 7, 2020 Share Posted August 7, 2020 Here is the table for a 36 yard zero with my 3 gun load (on the slow side) Link to comment Share on other sites More sharing options...
kurtm Posted August 13, 2020 Share Posted August 13, 2020 The very best 36 yard zero puts you dead on at 36 yards! For anything else..... Well you have to zero it at that range. Link to comment Share on other sites More sharing options...

LeadThrower Posted August 13, 2020 Share Posted August 13, 2020 It's a good way to get close enough at longer distances... making it easier to get on target. That whole "50/200" may be "close enough" for some shooters... but I find that it's still off by a few inches. Spend the time dialing in your rifle and ammo for actual, known distances... it'll give you a lot more confidence when pressing the trigger!

Enter your data into JBM Calculator and it will give you a rough idea. Link to comment Share on other sites More sharing options...
emjbe Posted August 15, 2020 Share Posted August 15, 2020 here's a good video on the topic and it shows holdovers on a target (about minute 4:00) Link to comment Share on other sites More sharing options...
PacMan Posted September 4, 2020 Share Posted September 4, 2020 I won't question the wisdom behind 36 yds zero, but here you go, direct from https://www.federalpremium.com/ballistics-calculator Link to comment Share on other sites More sharing options...
Jim Watson Posted September 7, 2020 Share Posted September 7, 2020 Depends on what you are shooting at and how far. I would call this 36 yard zero suitable for "full figure targets" to 350 yards. But if you want to be able to pull one plumb at 200 yards, you have to hold UNDER by 4.8". Link to comment Share on other sites More sharing options...

Silver_Surfer Posted September 28, 2020 Share Posted September 28, 2020 Found out by accident I've been using a 36yd zero and didn't realize it. I normally sight in at 50yds. Later I check my 100yd zero and adjust the bullet impact 2-3" high. Yesterday don't know why I wanted to see where I impacted at 36yds. i was blown away at the results. I 've been using a 36yd zero and didn't realize it. Boy I wasted a lot of time in the past. Link to comment Share on other sites More sharing options...
arcsign Posted January 8, 2021 Share Posted January 8, 2021 A little late to the party here, but for future reference... rather than pick a zero out of a hat, so to speak, you can use JBM or Strelok Pro to calculate your Max Point Blank Zero and Max Point Blank Range. Basic idea is you put in your load data and the maximum acceptable radius (or diameter, I don’t remember for JBM) for your application. Like, if you’re shooting steel plates that are 8x8, Max radius is that of the inscribed circle... so 4 inches, maybe 3.5 to be safe, and the calculator will give you both the maximum range that you can get away without holding over/under shooting center of target, and the zero to set to get that range. Example in the image. Link to comment Share on other sites More sharing options...
atlantixyl Posted February 19, 2022 Share Posted February 19, 2022 They have tried some canted shooting with the 36 yard zero. POI definitely shifts when axis of the bore changes, but it'a still combat effective 5- 7" circle up to a certain distance without even think about holdover.

emjbe Posted February 21, 2022 Share Posted February 21, 2022 When using a top mounted sight and holding in a canted position as they did in the article, the way i learned it was: > if it’s a target that requires it (e.g. far away) hold in the direction of the magwell. In my experience, I have to start holding in the direction of the magwell at about 70 yards. Note that for an offset sight mounted and zeroed at 45º you do not need to change your hold because that sight *should* be zeroed properly at its vertical position.

Muricanwerewolf Posted October 11, 2023 Share Posted October 11, 2023 You need to buy a chrono and a ballistic calculator. Doing anything else you're just guessing. Link to comment Share on other sites More sharing options...

pjb45 Posted October 18, 2023 Share Posted October 18, 2023 A chrono is one of your best friends. Most ballistic calculators will tell you the barrel length for their data. You lose fps for every inch your barrel is shorter than the test barrel. Relying on factory fps may result in less than accurate data, especially the further out you go. KM and SH are spot on.
