When shopping for a new riflescope or spotting scope it’s easy to get confused by all the technical terminology. Do you wish you had a better way to compare scopes — beyond just size, weight, and price? Well Swarovski Optik can help. The Swarovski Hunting Blog offers a helpful guide to technical terms used when comparing scope specifications. Here are some important definitions, expressed in layman’s language:
Objective Lens Diameter
The objective lens diameter determines the size of the optical system’s entrance pupil. The bigger the objective lens diameter, the more light the system can capture. However, the size of the objective lens does not determine the size of the field of view.
The size of the Exit Pupil is determined by the objective lens diameter and the magnification. If you look at the eyepiece from a distance of around 30 cm (11.8 in), the Exit Pupil appears as a bright disc.
For calculating the Exit Pupil the formula is:
Exit Pupil = objective lens diameter ÷ magnification (expressed in power number).
The larger the Exit Pupil, the more light will reach the eye.
Field of View
The Field of View is the size of the circular section of the area which can be observed when you look through a long-range optical device. In the case of rifle scopes, it is specified at a distance of 100 meters or 100 yards. For example, 42.5 m at 100 m or 127.5″ at 100 yards. As an alternative, the Field of View can also be stated in degrees (e.g. 6.6°).
NOTE: The technically-feasible size for the Field of View is essentially determined by the magnification. The higher the magnification the smaller the Field of View.
The Twilight Factor defines the optical system’s performance in poor light. The statement “the greater the twilight factor, the better the suitability for twilight” only applies if the exit pupil is larger than or at least as big as the eye’s pupil. The pupil in the human eye can only open to around 8 mm. As we get older, our eyes become less flexible, which limits our ability to see things in twilight or at night. Therefore [an optic's] exit pupil cannot always be fully utilized.
For calculating the Twilight Factor the formula is:
Twilight Factor = root of ( magnification x objective lens diameter ).
NOTE: Spotting scopes have extremely high twilight factors because of their high magnification and large objective lens diameter. But [when used at high magnification] their small exit pupil can make them [somewhat difficult] to use in twilight.

Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells Website. With these inserts, you can use a scope with 1″-diameter main tube in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. This way you can use the same 30mm rings for all your scopes.
Ring Reducers are sold as front/rear kits. Cost is just $19.99 for the 1″ to 30mm converters, item 084-000-091. There are also sets that reduce 30mm rings to 25mm, and 1″ rings to 3/4″ or 7/8″.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.

In the above video, a spokesman for Horus Vision explains how and why scopes can experience zero shift. First, just cleaning the gun can cause a small shift in point of impact. Second, when you re-tighten rings and ring bases, this can cause a change in zero. Horus recommends that you use a torque wrench to confirm that you maintain the same torque settings each time. The same goes for action screw tension — tensioning your action screws can shift the point of impact.
Other factors that can cause a change in zero:
Dramatic ranges of temperature will change your zero, because the air density affects the velocity of the bullet. With increased temperature, there may be a higher velocity (depending on your powder).
Gun Handling and Body Position
You rifle’s point of impact will be affected by the way you hold the gun. A “hard hold” with firm grip and heavy cheek weld can give you a different POI than if you lightly address the gun. Even when shooting a benchrest gun, the amount of shoulder you put into the rifle can affect where it prints on paper.
Type of Rifle Support — Bench vs. Field
Whenever you change the type of rifle support you use, the point of impact can shift slightly. Moving from a bipod to a pedestal rest can cause a change. Similar, if you switch from a mechanical rest to sandbags, the gun can perform differently. That’s why, before a hunt, you should zero the gun with a set-up similar to what you would actually use in the field — such as a rucksack or shooting sticks.
Transportation of Firearms
Even if you don’t mishandle your weapon, it is possible that a shift of zero could occur during transport. We’ve seen zero settings change when a tight plastic gun case put a side load on the turrets. And in the field, if the turret knobs are not covered, they can rub against clothing, gear, storage bags, scabbard, etc. If the knobs turn, it will definitely move your reticle slightly and cause your point of impact to be off.

If you’ve been considering the new Nightforce SHV scope for a hunting application, head over to LongRangeHunting.com. There you’ll find an in-depth field test of the 4-14x56mm SHV by Nicholas Gebhart. This is a very thorough review — Gebhardt checks every feature of the scope and comparison tests the SHV against the more costly Nightforce NXS 3.5-15x50mm. Gebhardt even put the SHV scope in his freezer for a weekend to ensure there was no fogging.
CLICK HERE for Product Specs and/or to Pre-Order Nightforce NXS.
Overall, Gebhardt was very pleased with the SHV: “Optical clarity, image brightness, contrast and resolution were all extremely good.” The tester also liked the MOAR reticle in his scope. He didn’t think it was too “busy” though he thought the hold-over lines would benefit from numbers: “Nightforce’s MOAR was easy to use and provided a clear sight picture for engaging small targets. The line thickness is perfect for both precise shot placement and visibility. My personal preference however would be for the even hash marks to be numbered for the entire lower portion of the reticle.” Gebhart noted that the SHV’s side parallax knob had yardage marking numbers that proved accurate (and handy to use) — most other scopes just have lines.
Nightforce SHV vs. Nighforce NXS
How did the new SHV stack up against the NXS in a side-by-side comparison? Gebhardt was impressed with the $995.00 SHV, saying it held its own with the pricier NXS model: “I took about 30 minutes to evaluate the optics of the SHV and see how it compared to an older Nightforce NXS 3.5-15X50. Both of these scopes are made in Japan but given the price differential, I expected to see some difference in the optical quality. To my surprise, I couldn’t find any optical difference between the two except for a very slight possibility of a brighter image with the SHV.”

Nightforce Optics has introduced a new medium-magnification, second-focal plane scope for hunters and tactical shooters. Described as “the most affordable Nightforce riflescope [offered] to date”, the all-new 4-14x56mm SHV will sell for $995.00 (non-illuminated model) or $1195.00 with an illuminated reticle. The “SHV” stands for ShooterHunterVarminter™, reflecting this scope’s versatility — it can be used for a wide variety of applications. The SHV has plenty of travel for long-range use: 100 MOA of elevation adjustment and 70 MOA of horizontal (windage) travel. Two reticle options will initially be offered, the basic IHR (Int’l Hunting Reticle) with floating center cross-hair, and the popular MOAR reticle with 1-MOA vertical and horizontal hash marks.
The 4-14 SHV scope represents a new direction for Nightforce. The optics-maker kept the price under $1000.00 by “limiting some options, offering simpler controls, and using a less complex manufacturing process.” Nightforce said the goal with the SHV was to offer a scope priced “within the reach of a wider range of hunters and shooters who don’t need the ‘overbuilt’ characteristics of our NXS™ series, most of which were originally created to withstand actual combat conditions.”
The 4-14x56mm SHV weighs 26.8 oz. for the basic version, and 28.5 oz. for the illuminated model. Full specifications are listed below. CLICK HERE for 2014 Nightforce Catalog.

A varmint shooter’s target is not conveniently placed at a fixed, known distance as it is for a benchrester. The varminter must repeatedly make corrections for bullet drop as he moves from closer targets to more distant targets and back again. Click HERE to read an interesting Varmint Forum discussion regarding the best method to adjust for elevation. Some shooters advocate using the scope’s elevation adjustments. Other varminters prefer to hold-over, perhaps with the assistance of vertical markers on their reticles. Still others combine both methods–holding off to a given yardage, then cranking elevation after that.
Majority View–Click Your Scope
“I zero at 100 yards — I mean really zero as in check the ballistics at 200 and 300 and adjust zero accordingly — and then set the scope zero. For each of my groundhog guns I have a click chart taped into the inside of the lid of the ammo box. Then use the knobs. That’s why they’re there. With a good scope they’re a whole lot more accurate than hold-over, with or without hash marks. This all assumes you have a good range finder and use it properly. If not, and you’re holding over you’re really just spraying and praying. Try twisting them knobs and you’ll most likely find that a 500- or 600- or 700-yard groundhog is a whole lot easier than some people think.”
“I have my elevation knob calibrated in 100-yard increments out to 550. Range-find the critter, move elevation knob up…dead critter. The problem with hold-over is that it is so imprecise. It’s not repeatable because you are holding over for elevation and for wind also. Every time you change targets 50 yards, it seems as if you are starting over. As soon as I got completely away from the hold over method (I used to zero for 200), my hit ratios went way up.” — K. Candler
“When I first started p-dog shooting, I attempted to use the hold-over method with a 200-yard zero with my 6mm Rem. Any dog much past 325-350 yards was fairly safe. I started using a comeups table for all three of my p-dog rifles (.223 Rems and 6mm Rem). 450-yard hits with the .223s are fairly routine and a 650-yard dog better beware of the 6mm nowadays. An added benefit (one I didn’t think of beforehand) with the comeups table (elevation only), is that when the wind is blowing, it takes half of the variables out of the equation. I can concentrate on wind, and not have to worry about elevation. It makes things much more simple.” — Mike (Linefinder).
“I dial for elevation and hold for wind. Also use a mil-dot reticle to make the windage holds easier. For windage corrections, I watch for the bullet strike measure the distance it was “off” with the mil-dot reticle, then hold that much more the other way. Very fast once you get used to it.” — PepeLP
Minority View–Hold-Over is Better
“I try to not touch my knobs once I’m zeroed at 200 meters. Most of my varmint scopes have duplex reticles and I use the bottom post to put me on at 300 meters versus turning knobs. The reason I try to leave my knobs alone is that I have gone one complete revolution up or down [too far] many times and have missed the varmint. This has happened more than once and that is why I try not to change my knobs if at all possible.” — Chino69
“I have been using the hold over method and it works for me most of the time but the 450 yards and over shots get kinda hard. I moved to a 300 yard zero this year and it’s working well. I do want to get into the click-up method though; it seems to be more fool-proof.” — 500YardHog
Compromise View–Use Both Methods
“I use both [methods] as well — hold over out to 250, and click up past that.” — Jack (Wolf)
“I use the target knobs and crank-in elevation. I also use a rangefinder and know how far away they are before I crank in the clicks. I have a scope with drop dots from Premier Recticle and like it. No cranking [knobs] out to 600.” –Vmthtr

Leupold has just introduced a new second focal plane reticle with MOA-based hashmarks, allowing precise hold-overs and hold-offs (for wind). The new TS-32X1 reticle, is a minute-of-angle (MOA) based system designed to allow for precision shots without the need for dial adjustments. The TS-32X1 reticle is designed to work with riflescopes that employ 1/4-MOA target adjustments or M1 dials.
The TS-32X1 is the first in a family of MOA-based reticles that will cover several magnification ranges. The TS-32X1 will be available for a wide variety of Leupold riflescopes. For $159.99, the Leupold Custom Shop can also retrofit this reticle into many existing Leupold scopes. Adding the TS-32X1 to a new riflescope ordered through the Custom Shop will cost $129.99.
MOA-Based Hashmarks on Horizontal and Vertical Stadia
On the TS-32X1 reticle, a heavy post and thin stadia crosshair features 1-MOA hashmarks on both the horizontal and vertical lines. Every other hash mark on the horizontal stadia is slightly longer, providing quick and easy 2-MOA measurements. There is a number placed every fourth MOA for quick reference.
The vertical stadia is also set up with 1-MOA tics and longer 2-MOA marks. In addition, every fourth mark is numbered, all the way to the complete 32-MOA elevation range. Wind dots in the lower half of the reticle are spaced in 2=MOA increments, both vertically and horizontally.
Product tip from EdLongrange. We welcome reader submissions.
This new TS-32X1 reticle is currently available for most second (rear) focal plane VX-3, VX-III, Vari-X III and Mark 4 4.5-14 LR/T riflescopes. Existing riflescopes can be retrofitted for $159.99 through the Leupold Custom Shop. To add the TS-32X1 to a new riflescope ordered through the Custom Shop is $129.99.
