Re: What distance is your zero?
I think the zero depends upon intent, we need more information to make that determination.
If you're shooting groups at the public range...100 yards. Easier to shoot groups with the cross hairs dead on.
If you're practicing sniping at Thunder Ranch...600 yards. You can easily use comeups for the range you need.
If you think it might be the gun to use for social instability...200 yards. Most urban areas don't have shooting opportunities further than 200 yards.
If you itend to hunt with it...300 yards. The bullet strike will be close enough for any practical hunting situation, you can hold dead on.

Re: What distance is your zero?
100 yards is still the standard, most dope is based on 100 yard zero.

300 yards zero for my TRG 42, got dope to 1000, then i got software.

Using an m24 with a rail system? It probably adds ~20moa to your base, depending on your scope you might not have enough elevation to get down to 100 with that added 20 moa, probably best to zero at 300 and hold off or have the spotter take that shot inside 300 provided he has an spr of some sort.
</div></div>
Every M24 I ever dealt with to include my own had a flat base, not a 20 moa. Could dial down to 100 meters but we still zeroed at 500 meters instead.
At one point we did have 1/4 moa click scopes on our Barretts but we switched them out before long for larger adjustments. We zeroed them at 500 meters as well for easier hold-offs.

Re: What distance is your zero?
My 40XB .308 is zero'd for 300 yards with come downs/ups in 50 yard increments from 100 yards to 1000 yards, my 6.5X55 TPG-1 is zero'd at 100 meters and using 50 meter increments come ups to 1000 meters.
I suppose you zero your rifle for whatever range your going to encounter targets mostly at and work off that.

Re: What distance is your zero?
quick question for whom ever....marine cmp's teach that a 223 isnt effected by wind till 300, on the range we teach the same thing, no wind call at the 200 unless its gale force winds. are 270, 308, 300 win mag and all the other preferred cals that effected by wind that you need wind calls at the 1, 2, and 300 marks?

Re: What distance is your zero?
most typical shooting ranges allow only for a 100 yd shot. It is relatively easy to work from that as a base so I leave mine @ 100yd

Re: What distance is your zero?
I have my rifle sighted in at 300 meters simply because it is more accurate than a 100 meter sight in. All variables get pronounced at 300 so a slight error in vertical adjustment that might not be visible at 100 meters is very visible att 300 meters.
In the comps I participate in, 2 cm high att 100 meters is still a center hit but 6 cm high at 300 meters isn't.
In my self, I have also seen a mental edge of the 300 zero. I feel calmer and more confident in engaging long range targets when my zero is closer to the actual distance.
Lastly, I also belive that spin drift will be less pronounced when your zero is further out.
The kind of shooting I do is hunting and competitions between 100-650 meters.

Re: What distance is your zero?
my 308 is set at 100, there is so much ballistic info for the FGMM ammo that it works great.

Re: What distance is your zero?
I personally don't think it matters. Get a zero, and plug it in to your favorite ballistic software and get your dope.

Re: What distance is your zero?
50 yds on the 2 rifles i own:
.223 16" AR-15 (scope is has 10 mils of hold over in the reticle)
.22 Ruger 10/22
i like the 50 yds zero because at 200yds the ar15 is right back to point of aim. i hold under about an inch or so for 100yd shots @ the local range, i.e. aim at lower part of soda can & hit it in the middle. i'd probably go with a 2-300 yds zero on a .308, but i've never owned one

Re: What distance is your zero?
This will prob make you wonder but mine is zeroed at 200, 300, 400, 500, 600, 700, 800, 900, 1000 and one position left for future use. I'm using a Variable Gantry 10 position mount that lets me preset at 10 differnt distances for Zero. Then using my plexes it covers the distances in between based on my trajectory charts so no adjustment of the scope is needed.
Like others have said, your zero needs to be based on what your equipment and type of shooting you will be doing. Some scopes have plexes/subtensions or dots that would let a shooter cover all their needed ranges with no adjustment. Others with better equipment may be able to zero closer and crank in adjustments as needed reliably. I don't have a good scope option so I needed a way to bypass cranking on my scope for differnt settings.

Re: What distance is your zero?
I've seen one of those. It gives you a really high height above bore. Here's a link:

Re: What distance is your zero?
The 5 position mount does sit on top of your regular mount and is higher but the 10 position is machined to fit right on top of the action. Chris (the maker) says he has no problem with the heights of the mounts on his rifles even without an adjustable cheekpiece. That isn't a problem for me since I don't have to worry about cheek weld and it being a bit higher above my bore line doesn't matter since each distance is preset. The trajectory charts work out nearly perfect when calculating the hold but many have commented on it being high above the bore but is a non issue at least in my setup.
The mount on the left gun (7-08) is the 5 position and the one on the right (260) is the 10 position.

Re: What distance is your zero?
Interesting concept with Variable Gantry 10 position mount. I have a scope with zero-stop. So I zero at both 100 yards by setting zero-stop there, and at 200 yards by setting dial "0" there.

Re: What distance is your zero?
For all these hold-over/hold-under calculations (<span style="font-style: italic">Lindy, I read your article on this!</span>), how much does your cartridge's load (<span style="font-style: italic">bullet weight, powder type, MV etc.</span>) affect these hold-overs/unders? I shoot a .308 w/168gr. SMK's.

Re: What distance is your zero?
Ah, so I have to figure out all those hold-overs on my own. You're example was just that...an example. Thanks!

Re: What distance is your zero?
Yep, unless your dope is identical to what I used on the web page Calculating Holdovers and Holdunders. The purpose of the web page was to illustrate how to do the calculation, so you can do so with your own dope.

Re: What distance is your zero?
Topstrap,
I would love to shoot one of those on the short course!
Can't afford to work on the others right now, but I know how much fun it is.
We are still talking about you guy's!
My pistol scopes are 2's and 4's.
Thanks

Re: What distance is your zero?
Average target range for course can come into play too.
Short is 300 plus and long is 550.
longest target is around 1150. bonus 10 point for 1650, all five in under 8 min.(two man team, both shooting)
Working on zero for different gun on short course
As I said before, we call in MOA.

Re: What distance is your zero?
My range is 100 yards so gather zero data there. Then dope as required. Using Litz's G7 data .223 rem with both Hornady 68gr and Sierra 69gr HPBT was within 1 click (.285moa on my gun) at 570 yards (1.7" low) (both 25.0gr varget and within 1 click zeros) Was a first round hit, up 1 click then dead on.
When setting for Coyote hunting use come up for 250 yard dope then never above 3.0" and only 3.7" low @300 yards. Hold dead to 300 ok.

Im zero'd at 600 meters. If I have to shoot closer than 600 I just use my side arm.

Re: What distance is your zero?
100 yard zero for me. All of my information and learning has been from 100 yards, so I am comfortable with it.
That, and I don't want to walk 2 or 300 yards to check my targets. LOL!!
