I am interested in purchasing a scope for a 7mm Ultra Mag.  I will be hunting Whitetail Deer in central Virginia.  I plan on taking shots ranging from 100 to 350 yards long. 

 

For several months I have been doing research on the Leupold VX-III 3.5-10X50mm.  I decided on the 50mm objective to retain the requred 7mm exit pupil at higher magnifications.  While performing this reseach I stumbled upon Opticstalk.com and found it to be very informative.  I noticed several subscribers have given great praise to the Bushnell Elite 4200 (2.5-10X50mm), the Nikon Monarch UCC (3.5-10X50mm) and the Zeiss Conquest (3.5-10X50mm).  Maybe not in those specific magnifications or objective sizes but certainly those brands and models. 

 

I am mostly concerned with low light performance for shots to be taken at dawn and dusk.   In terms of glass quality, coatings and overall clarity how do these scopes mentioned above compare to the Leupold VX-III?  Leupold indicates that the VX-III has an Index Matched Lens Coating System.  Does this mean that the lenses are Fully Multi-Coated or just Multi-Coated?

 

How many lenses do each of these scopes have compared to the Leupold?

 

Will these scopes provide sufficient eye relief for the 7mm Ultra Mag?

 

Does anyone have any exerience with the Wide Duplex Range Estimating Recticle offered on the Leupold?

 

Which is more important Exit Pupil or Twilight Performance?

 

They all have 1" single piece main body tube construction, hand adjusted 1/4 MOA's and decent warranties?  Correct?

 

I really need some help!  All this is just too much to consider.  Chris/Brady?

 

Thanks

I had a Leupold VX-III 3-10x40mm on a Weatherby Mark-V Super Big Game Master chambered in .300 Win Mag. The rifle weighed 6 3/4 lbs. unscoped and the scope added approximately 13 ounces to overall weight. This combo performed well for me.

 

Your Leupold will provide enough eye relief  to be used on the 7 Mag, provided your are not a severe "stock crawler."

 

All lenses for this particular Leupold are fully multi-coated. You can phone Leupold or Chris  and they can tell you the % of light transmission for the particular model you're interested in and the type of coating used on the lenses.

 

As for the range estimating......the Boone & Crockett reticle has established hold over points not a range estimating reticle. On a VX-III you can estimate the range of a whitetail or similar sized animal by bracketing the animal with the thin area of the crosshairs & reading the number on the power selector ring and multiply the number on the selector ring by 100 to give you your estimated yardage...it's a very simple process if the buck gives you time. I would recommend a good range finder from SWFA versus using the scope as a range finder, that way you can predetermine your ranges (depending on the type of hunting you're doing) and then use the Boone & Crockett reticle for precise shot placement depending on yardage and wind deflection. (I believe Zeiss offers a similar reticle.)

 

The type of glass, coatings and brand of scope is more important than exit pupil and twilight factor. Exit pupil and twilight factor are nothing more than mathematical equations that arbitrarily assign a number for exit pupil and twilight factor. They do not take into consideration quality of glass, coatings and manufacturing tolerances.

 

Leupold & Zeiss carry excellent warranties, I don't know much about Nikon and Bushnell (Don't care to either)

I do know that the Nikon, Bushnell and Zeiss are heavier than the Leupold. You may consider this if weight is a factor. Remember ounces make pounds!

 

If you are age 40 or over you shouldn't be concerned with a 7mm exit pupil, your eyes will probably only dialate to 6mm or so. And to be honest I don't know if the human eye can distinguish the difference between a 6mm or 7mm exit pupil.

 

I feel that the Leupold is a good bang for your buck scope that will serve you well for what it will be utilized for, but from what I've read here, as far as mid-priced scopes are concerned, the Zeiss Conquest is the "Stud Duck"  

The Conquest has great clarity and low-light performance (from what I've read) and it has a square reticle adjustment (This means that windage and elevation adjustments won't affect each other), a feature which I find very appealing.

 

Good luck, happy hunting. Take it from here Chris!

Well, I'm not Chris. But I did stay at a Holiday Inn Express last night.

 

I'd take the Conquest over the Leupold.

 

Fixed eye 4" relief

Laser etched reticle

Optically a little better than the VX-III

(I'm aware that's a matter of opinion.)

 

Either way, all scopes you listed will serve you well.

I don't have a lot of technical knowledge of this sort of thing but I've had two of the Leupold 3.5-10x50's for years, one on an A-Bolt in 30'06 and one on a Win. 70 in 270.  I bought the first of the scopes the year they came out.  Over the years I've probably used those combos to kill 50 deer.  Other scopes (the 4200 fo example) would probably have served me as well, but I don't see how you could improve significantly on the Leupold without spending way more money.  I'm 56 and ned all the help I can get light-wise.  I've been flirting with a Schmidt & Binder for at least one of my guns but every time I start to write the check my mouth gets too dry.

I wouldn't worry much about range-estimating with the reticle. That can be done very simply with any reticle with at least 2 stadia for reference, faster than the Range-estimating system Leupold uses, and with fixed or variable at the highest magnification. The system is based on the mil-ranging formula. If u're interested let me know and i'll break it down for u. Oh, and the Boone and Crockett reticle does offer their range-estimating system using the x-hair to upper post as a reference.

My pick would be a Zeiss Conquest 3-9x50 for a low light scope. Of course the Leupold VX-III is a very good scope as well, and I do like the B&C reticle over Zeiss's ZRF reticle. You cannot go wrong with either one IMO.

Hey i found it under search-- good feature.

 

I've been doing ranging research for a few years now, and have found that the best way to reticle range is to use an adaptation of the mil-ranging formula. Understanding this formula is the secret to ranging with any reticle and any tgt. size. 1 of the permutations of the mil-ranging formula (inches to yards) is this--

 

tgt size (inches) x yards/stadia subtension (inches)= target stadia factor/stadia-stadia  "gap" target occupies = range in yards

 

Looks complicated, but actually easy once u try it a couple times. Now just fill in the variables to get yardage. But the whole idea here is that u must know 2 of the 3 variables to be able to calculate the other variable (the most important of which is stadia subtension to be able to use the system with the most flexibility-- which we don't know the ZRF subtensions, BUT they can be calculated by manipulating the formula). Under the Search function Chris gave us 2 of those-- tgt. size of 50 cm.(19.69"), and range of each stadia, #1 = 100 meters (109.36 yards), #2= 200 m. (218.74), etc

 

Now just plug in those figures to calculate each stadia's subtension in inches @ 100 yds.--

 

1) x-hair to line 1 subtension= 19.69" x 100 yds./ X = tgt-stadia factor

 tgt.-stadia factor/ 1 entire stadia-stadia unit=109.36 yds.

 

or, X= 1969/109.36= 18"--- this means that the x-hair to line 1= 18.0" @ 100 yds.

 

2) x-hair to line 2 subtension= 19.69" x 100 yds./X/1 = 218.74

 

or,  X= 9.0" @ 100 yds.

 

3) line 3= 6.0"

4) 4= 4.5"

5) 5= 3.6

6) 6= 3.0

 

Now we know each reticle ranging subtension in inches, so suppose you're after mule deer, which according to this site http://www.kahlesoptik.com/products/animal_silhouette.html measures 22" back-brisket. Just plug that figure into the modified mil-ranging formula like this using line 2(9.0") as your std. for ranging to create a range chart--

 

22" x 100/9.0"/1.0 gap = 245 yds.

22" x 100/9/.9 gap = 270

22" x 100/9/.8 = 300

.7= 350

.6= 405

.5= 490

.4= 610

 

Now here's the nice thing about all these multiple stadia (including simple plex) reticles. If we divide the std. ranging stadia (#2 for our mulee) into each of the smaller stadia subtensions we get the percentage of the std. ranger each of the stadia represents in tenths of the total ranging unit, i.e.

 

#3 = 6.0/9.0= .7 of the total gap between x-hair and line # 2 == 350 yds.

# 4= .5 == 490

#5= .4 == 610

6= .3 (forget it-- too far/too inaccurate)

 

Now we can use each line to figure the interpolation for bracketing purposes. Zeiss already did all this without all these calcs., but the system i've outlined allows for a huge amount of flexibility with any reticle system (1st or 2nd focal plane), for any size tgt.-- which really provides a huge advantage over the much less flexible stds. the optics companies offer.

 

The End

Personally i wouldn't go with the ZRF reticle since i want a reticle that has downrange zeroing, ranging, and windage reference all in 1-- u could manipulate the ZRF for that, but it'd be too complicated-- especially when there r some out there that provide it more efficiently-- Leupold's VH, B$C , TDS.

Accoring to Zeiss the Conquest's lenses are only multi-coated.  If fully multi-coated lenses are supposed to provide better low light performance than only multi-coated lenses then why would the Zeiss be clearer that the Leupold VX-III which according to Stud Duck has fully multi-coated lenses?  Is it becuase the quality of Zeiss' glass is that much better?

 

I just want to make sure I have all the facts before spending $500 - $600.

I would assume it would be due to the quality of their glass, but I'll let an expert handle that one.

To the best of my knowledge Zeiss Conquest glass is fully multicoated.  IMO, Conquest is better optically than VX-III.  Then again this is from a guy does not buy anything German (if there is any alternative at all) and is not a big fan of Leupolds.

VX-III 3.5-10x50mm

http://www.leupold.com/products/products_highlights.asp

http://www.leupold.com/products/magnified/images/VX-III/VX-I II_3_5-10x50_XL.gif">

Eye Relief (in): 4.4(3.5x) 3.5(10x)

Max. Adjustment @ 100 yds (in): 51

http://www.nikonsportoptics.com/product.php?group=16&sub group=10&product=6535

http://www.nikonusa.com/images/products/6535_360.jpg">

Eye Relief (in): 3.9-3.8

Max Internal Adjustment: 45 MOA

 

Tough call.

The NIKON has what appears to be constant eye relief, and might be a bit easier to mount ( more room between the saddle and objective lens ).

The Leupold has a little more, but only at the low-end, but it's about 1.5" shorter and a 1/2 oz. lighter...

 

I'd pick one or the other, depending on how it will fit your rifle and budget, and be happy with either choice.

I have both Leupold and NIKON scopes.  The NIKON's look clearer to MY eyes.  Your view may be different.

Good Luck on this one!

I just bought the Zeiss Conquest on it sits on my 7 Mag and I love it!

 

I spent three months researching, mostly on this forum and discovered the majority favored the Conquest over the Leupold VXIII.
