At what range do most of you sigt in you varmint rigs? I have my swift in for 3/4" high at 100 yards but see some are zero at 100. Just curious.

I like to scatter the groundhogs when I hit 'em, so I use a .270 or a 30-06, either one zeroed for 300 yards.

It ain't fun if they're any closer than that...

But that's just me!

I zero all my guns at 100 yard.Use a rangefinder and drop chart And click to the range I am shooting.Here is a drop chart from one of my guns.It starts at 500 yard's but I cropped the top off of it .This gun is still zeroed at 100 yard's.But I don't get it out til the ranges are over 500 yard's

I sight my 2 22-250's in at .5 high @ 100. This works for me, as I shoot out to about 500yds. From 1-200 I don't have to click a thing. Everyone has their own preference. If one has a battery of rifles in say short, med. and long range
I would zero about in the middle of the particular calibers optimal perfomance range.
Goood shooting! Sam

Geez, I thought half the fun of varmint shooting was range estimation and wind doping. I guess next I'll see some sport with a lazer range finder hooked into his lap top..............
I'm a pairie dog shooter and I sight my rifles in 1" high at 100 yards and start shooting dogs with a center chest hold. When I start missing low, I go to a center head hold. After that it really starts to get challenging with over the head holds. The same deal with the wind. Its easier to consistantly hit with a fairly stout steady wind than with a lighter wind that gusts.
Once I start shooting, I don't dial in nothing.
I use a 6x24 scope and seldom use the top end of it as mirage starts playing with you. Also, if you need the 24x to see the dog, your chances of hitting it are pretty non-existant.

Boyd, I am curious about what cartridge you are shooting, or am I reading your chart wrong? 1900 yards and only 66 inches of drop with a 100 yard zero?

I would have to assume that the numbers are MOA...

Dan

788,You assume correct .Could also be 66 inch's at 100..............

Boyd,can you crank in 260 something clix and back without losing your zero.I can go up to 500 yards and back and still be there but thats as far as I have tried it.

8.5-25 LRT Leupold.Gotta be the best varmint scope I have used.

Mr Big,That drop chart is for an 8.5-25x50 Leupold LR scope.....So you answered your own ?

My .223 is zeroed at 200 yards, I use "hogs" or "dogs" to adjust for windage or elevation.

I hate to admit it, but that drop chart went right over my head.

Don't feel bad Tony. It went over mine too.

A minute of angle, or MOA, is about one inch at 100 yards, two inches at 200, 3 at 300, etc.

Boyd's chart shows 20.9 for the 1000 yard zero. That would simply mean that he moves the scope's elevation turret 20.9 MOA to be on zero at 1000 yards. (You would also have to allow for elevation, wind, etc., but that's basically it).

Many scopes are marked with MOA scales. Those which are not can normally still be used to "dial in." A scope with 1/4" clicks (most of them have 1/4" clicks) is dialed four clicks for 1 MOA. 8 clicks for 2 MOA, 12 clicks for 3 MOA, etc.

For 20 MOA, if you had a scope with conventional click turrets, and enough elevation to go there, you would dial 4 clicks per MOA unit, or 80 clicks. For 20.9 MOA, you'd dial the 80 clicks plus four more, which would actually be 21 MOA, but you'd be close enough...

All of the above is subject to correction by those who are better informed than I am.

Dan

right on the money there.

It is 66.4 moa.Not inch's.My gun would be 66.4 inch's high at 100 yard's to be dead on at 1900 yard's..I'm sorry,I just thought everybody would know what I meant ...It is a 300 Ultra............

NB: I have many different Varminters and each has a different zero yardage. I keep track of the zero range and the trajectory with a simple paste on chart in the top inside lid of my MTM style ammo boxes. They list the zero distance and the trajectory (P.O.I.) every 100 yards from 100 to 500 yards. I only have a few Varminters with label charts to 600 yards (for instance my 6mm Ackley Improved and my 240 Weatherby custom Varminters). I limit myself to shots past about 450 yards to days when the wind is not "difficult"!
And on the other end I seldom shoot Colony Varmints (Prairie Dogs and Rock Chucks) any closer than 150 yards. Unless the rancher or land owner really wants his Varmints "thinned out"!
Many of my Varminters are shooting 2 to 2 1/2" high at 100 yards.
Hold into the wind

after thinking on this at work today I remembered that it was zeroed at 1900 so 66 inches high at 100 you would actually be rising out to about 1250 or 1300 for your highest point before starting back down.

I zero my at 200y. This way I don't have to do anything if they are much closer and don't have to do as much if they are much further.

All my varmint rifles are sighted in one inch high at 100 yards.

I site my 223 XP100 in at 200 yards and I hold for a ground squirrels neck, which lets me shoot from 100 - 250 yards. I zero my 243 Win at 300 yards so I can use a neckhold out to 400 yards. After that, it's guesstimate time.

I zero my short range stuff (17M4 and 221FB) for 200 yards. Longer range calibres are zeroed at 100, and then I use the turrets to adjust for the lasered range. If I'm in a situation where I won't be able to adjust the turrets, then I wind on the 200 setting.

My .223's I normally end up zeroing about 1-3/4 to 2" high at 100, as that puts them pretty much on the money at 200, and about 7 to 8" low at 300, w/ most loads in the 50-55gr range. I normally start out holding right at where the prairie dog / rock chuck meets the ground so at less than 200, I get some awesome air when they pop up out of the hole (can we say, "Confirmed kill!"?) Down side is that I've had more than a few at a shade over 200 that the bullet hit the mound, and bounced the dog in the air, and it came down looking around for what the hell was happening, not a scratch on the damn thing. Grrrr.... As they get further out, I start holding over a bit. When I'm about 1 dog high, I'm at about 300yds. Beyond that, I'm doing a Hail Mary anyway w/ my .223 and the Nebraska winds...

Monte

Oh those Nebraska winds!!!

If the chart is MOA and the scope adjusts for 1/4" at 100 yards, wouldn't there be issues at the longer ranges? I thought MOA was something like ~96 yards. At 1000 yards, I would think that would equate to difference of ~40 yards or so. Where am I going wrong here? Is it kind of MOA with the table being set up to read 4 click at 100 yards as opposed to 4 clicks at MOA? Does this even make sense?

As far as my zero range, I sight in for 1"-2" high @ 100 depending on the cartridge and conditions.

MOA at 100 yds is about 1". MOA at 1000yds is about 10". 1/4MOA at 1000yds is about 2&1/2".HTH
