RiggerJJ Posted September 29, 2018 Share Posted September 29, 2018 Heck, I shoot groups/zero at 300 with iron sights (or 1x) after I have installed a new sight. Link to comment Share on other sites More sharing options...

RiggerJJ Posted September 30, 2018 Share Posted September 30, 2018 With iron sight? I'm happy with 6 inches, knowing fully well that most of that 2 moa is me and not the gun... Link to comment Share on other sites More sharing options...
yosturm Posted October 15, 2018 Share Posted October 15, 2018 200yard zero is best yard zero no matter what the zero you will have to know your holdovers for the 5 to 15 yard close in stuff, then beyond that you are within 2 inches out past to 240 yards. also it is the zero I use for every rifle so all of my offsets are basically the same.

AverageJoeShooting Posted March 3, 2019 Share Posted March 3, 2019 200 yard zero that way no matter the distance you arnt more than 2 inches off. since you only need to hit the target in 3 gun i just know my holds at 300 and 400 as well as 100 and closer Link to comment Share on other sites More sharing options...
RAINY0DAYS Posted March 5, 2019 Share Posted March 5, 2019 Zero at 50, verify dope at all other distances I plan to shoot. 50 is not 200, but it's pretty damn close and makes remembering the curve for .223 pretty easy. Only time you have to hold over is up close or past 200. For everyone talking about zeroing at 200 and beyond, you may want to take a look at what the PRS guys are doing. There's a reason they all have 100 yard zeroes. Sent from my moto x4 using Tapatalk Link to comment Share on other sites More sharing options...

RAINY0DAYS Posted March 5, 2019 Share Posted March 5, 2019 Because they dial for everything possible so it doesn't matter where they zero. Or so they tell me.Yep, and because going much past that just introduces more variables such as wind, temp, etc. Zero at 50 or 200, it doesn't matter. I can shoot the same groups with either zero. But 50 is a hell of a lot easier to repeat and not have to worry about having a perfect windless day to zero.Sent from my moto x4 using Tapatalk Link to comment Share on other sites More sharing options...
RiggerJJ Posted March 5, 2019 Share Posted March 5, 2019 If you are having wind affect your bullet path much at 200, you are either shooting in a gale force wind, or shooting really light bullets. My ballistics say not quite 2 inches at 10mph direct cross... So any horizontal stringing within 2 inches is considered nil to me when rezeroing at 200 after putting it on paper at 50. 50 is NOT 200, any slight error at 50 will show up at 200. If you don't shoot 200 or beyond don't bother. But if you are using a rifle at rifle distances, you will be better off to check and re-zero at 200, once you have done the first step of getting on at 50.

I just recently wasted a bit of ammo learning this the hard way. I've always done the 50=200 zero with acceptable results but the one time during load development I didn't fine tune at 200 yards I sent a lot of rounds to 500 trying to figure out why things weren't truing up with my ballistics calculator or BDC reticle. Turns out a 50yd zero is just too coarse, I checked it at 200 and realized how far off I was, fine tuned it at 200 and now all of the sudden all my chrono numbers, BC numbers, reticle and Strelok are working in perfect harmony with my impacts out to 500 yards.

RAINY0DAYS Posted March 5, 2019 Share Posted March 5, 2019 Which is why I say to verify at distance. Very rarely do I ever find I have to make an adjustment after a 50yd zero though. If I'm zeroed at 50, verified at 200-400 and beyond, what is the point of rezeroing at 200? There is none other than just making things harder on yourself. All you're doing is introducing more variables and possible shooter error. Sent from my moto x4 using Tapatalk Link to comment Share on other sites More sharing options...
RiggerJJ Posted March 5, 2019 Share Posted March 5, 2019 Some of my ballistics on different guns show that with a 200 yard zero my poi at 50 can be off by as much as 3/4 of an inch. Imagine what kind of error at 200 that would be if I zeroed at 50 and just left it. Just like Tony says above... We are saying pretty much the same thing I think, but I go even further. I don't think I'm going to induce any error... I "zero" (put it on close) at 50 then zero at 200. I just prefer to put it on at 200, then verify at longer. I even us a 6 inch high by 4 foot long calibration bar made of steel at extreme distance, (600 for a 223, 800 for 308 or a precision gun) to correct my ballistics chart and zero... I want all of my competitors to zero at 50 and leave it... All of this is done with elevation only. I will pick a calm wind day to zero the windage, at as far as I can, but at least 200. And to make it even more confusing, for my iron sight rifles I zero at 300... Link to comment Share on other sites More sharing options...
DaleGribble82 Posted March 18, 2019 Share Posted March 18, 2019 (edited) My Athlon Midas BTR 1-6×24 ATSR1 SFP IR MOA calls for a 50 yard zero to coincide with the 600m BDC. So far has worked well for me. Edited March 18, 2019 by DaleGribble82 Link to comment Share on other sites More sharing options...
kurtm Posted April 4, 2019 Share Posted April 4, 2019 300 for iron sights is mandatory, not just a good idea! 200 minimum for a scope. In general, the more sight to bore offset, the farther you should go.....and yes people can and do shoot groups at 300..... any of you steely eyed 3-gunners ever heard of Hi-Power or Service Rifle matches??

usmc1974 Posted April 4, 2019 Share Posted April 4, 2019 (edited) Myself, if I'm running a 2 MOA red dot, I zero at 300/25 yards. the most the time I'm running my Burris Mtac1-4 AR and a zero at 100 yards For long range precision. I zero at 300 yards, run, strelok pro 4.7.4 Edited April 4, 2019 by usmc1974 Link to comment Share on other sites More sharing options...

recoilchamp Posted April 24, 2020 Share Posted April 24, 2020 I zero at 100 since that's the peak of the curve and I know every other distance will be below it. My Burris XTR II has zero stops that make it difficult to adjust up, so this way I know all trajectories will be below it. Link to comment Share on other sites More sharing options...
dekindy Posted May 16, 2020 Share Posted May 16, 2020 My Vortex 1x uses a 100 yard zero and cap has adjustments in 100 yard increments.Sent from my SM-G920V using Tapatalk Link to comment Share on other sites More sharing options...
Bowman Posted May 23, 2021 Share Posted May 23, 2021 Depends a bit on the optic but I generally zero at 200 yards. If you had a very small target at 100 yards you would have to hold slightly low but for most targets out to 250 yards a 200 yard zero works great.

Muricanwerewolf Posted June 7, 2021 Share Posted June 7, 2021 People keep saying their zero as if just that single number (50,100,200) means anything. The speed of your bullet as it leaves the barrel and what your scope reticule looks like (is it BDC, MOA, Mils) is what informs your zero. You want to match those hashes for as close to round numbers as you can get, for example 300,400,500,550,600. For me, with my bullets and an MOA reticule that means adjusting to a 155yd zero after putting all my data into strelok and originally zeroing at 200.

Silver_Surfer Posted June 7, 2021 Share Posted June 7, 2021 Now a days because of Practicscore I now sight my rifle in for the furthest small knock down plate in the COF. Link to comment Share on other sites More sharing options...
