Now through September 2, 2012, you can save big bucks on “factory blemished” Leupold VX-3, VX-L, VX-7, and Rifleman series scopes at MidwayUSA. Prices are slashed by as much as $260.00, and MidwayUSA is offering free shipping as well. These scopes may have minor cosmetic blemishes (small scratches, dents or ring marks) which do not impair function or reliability. All these “blem” scopes still carry Leupold’s full lifetime transferrable warranty.
The scopes on sale are mostly mid-power hunting scopes (2.5-10X, 3-9X, 3.5-10X, 4-12X etc.) with 1/4-MOA clicks. Savings can be substantial. For example, the 3.5-10x50mm VX-3L Rifle Scope was marked down to $519.99 from the regular $699.00 price — a $180.00 savings. If you want to take advantage of this special “factory blemished” Leupold scope sale, act soon — these are selling out quickly. The sale expires September 2, 2012.
Sale tip from EdLongrange. We welcome reader submissions.
Do you have a nice scope mounted to a “safe queen” rifle that never gets used? Or maybe you have a set of premium binoculars you bought for that Alaskan hunting trip you never got to take?
Now you can convert those valuable optics into cash with the SWFA Trade-In Program. You can either sell your gear outright to SWFA, or trade your items in on new products. Just fill out an online appraisal form, upload a photo, and SWFA will evaluate your submitted product. You can designate whether you want to sell your item outright, or trade it in on new gear.
Trade Your Pre-Owned Optics or Firearms
While SWFA specializes in optics, you can also trade-in firearms, or even barter hunting holidays. SWFA says: “We gladly accept trades on just about anything of value (firearms of any type, scopes, binoculars, spotting scopes, hunts). You never know unless you ask!”
Note, you must submit an Online Appraisal Form for all items submitted for trade-in. In addition, SWFA needs a digital JPEG photo of each item, 400 pixels wide and 300 pixels high.
Unlike benchrest shooters, hunters need to be able to make shots with significant up-angles or down-angles. That whitetail buck may be poised on a ridgetop above you, or in a valley below. When making an angled shot, the hunter faces a complex ballistic solution. This is because the angle of the shot alters the effective ballistic distance to the target. Whether you shoot up-angle or down-angle, you must adjust your elevation “clicks” as if you are shooting a shorter distance. See the diagram below. The drop of your bullet is a function of gravity, which remains constant. When you shoot at a steep angle, the actual bullet travel over the ground will be less than the sloped distance to your target.
But how do you determine the flat-line or “gravity-corrected distance”? There’s a simple tool that will do the job: the patented Angle Cosine Indicator (ACI®) invented by U.S. Army Veteran Ward Brien.
When you aim your rifle at an angle, the ACI shows the cosine value of your intended shot by means of a highly visible index mark. You simply multiply the true, sloped distance to your target by the cosine value (as a percentage), to get the corrected, flat line distance to target, i.e. the bottom leg of the triangle. Then set your scope’s elevation accordingly. For example, if you range the line of sight distance to your target at 400 yards, and the ACI shows a cosine value of 0.87 (for 30 degrees), then your flat-line “gravity-corrected distance” is 400 x 0.87 = 348 yards. Now Dial your elevation for 350 yards (from your come-up table).
This simple multiplication method works well for typical 100-300 yard hunting distances, but it’s not perfect. For longer-range shots, out to 1000 yards, some other factors come into play. The most accurate method for long ranges is to input the cosine number into ballistic software, such as Exbal Ballistic Targeting Software, that runs on a PDA or smart phone. The software takes into account the fact that, during an angled shot, the bullet must still travel the full distance to target, and will have a longer time of flight than when covering the flat line distance. At very long ranges there can be as much as eight (8) MOA difference between the simple multiplication method and the solution generated by the ballistic software. NOTE: ACI Inventor Ward Brien has posted a Comment to this article which explains in greater detail why inputting the ACI value into a ballistics program is the “preferred method”.
The Angle Cosine Indicator costs $145.95 from Sniper Tools. The ACI is made from aircraft grade aluminum, anodized flat black. Angles are laser-engraved onto the body in five (5) degree increments. The lens is water-resistant, shatter-proof, and shock-proof. Completely mechanical, there are no batteries or electronics to fail. For more info, visit SniperTools.com, or call (818) 359-0512.
SniperTools.com also offers an Angle Degree Indicator (ADI) for $114.95 (Civilian model). This shows the actual angle from horizontal. If you have a mobile ballistics solver, you can simply input the angle and the ranged yardage and the solver will provide the flatline “gravity-corrected Distance”. Some shooters find it easier to think in terms of the actual angle deflection from horizontal.
There are several ways to mount an ADI or ACI. We prefer a 90° slotted mount attached to a Picatinny rail. SniperTools.com sells a Badger Ordnance ACI/ADI Rail Mount for $60.00.
Those of us over-40 types can use some help when shooting iron sights. As one gets older, your eyes lose the ability to rapidly adjust to different points of focus. In practice, when shooting a rifle, this means the target image may be sharp but the sights are blurry, or vice-versa. Or you may be able to see the target and front sight reasonably well, but the rear sight is a complete blurr. (That is this Editor’s problem when shooting a rifle, such as a Swedish Mauser, with a notched blade rear sight.) Even if you are using a rear peep sight, you may see a blurry rear circle (or two circles if you have astigmatism). Placing a diopter on your shooting glasses can help many people see open sights better, when shooting both handguns and rifles.
Merit Corp. in Schenectady, NY, offers an adjustable metal diopter that attaches to shooting glasses with a rubber cup. Though primarily intended for pistol shooters, the Merit diopter can also be helpful when shooting rifles with open sights, such as military bolt actions. Priced at $65.00, the Merit device features a shutter-style adjustable aperture iris.
Merit explains: “The human eye, whether or not prescription glasses are required, cannot focus on both sights and the target at the same time. The eye will constantly shift focus from the sights to the target trying to ensure proper alignment. Unfortunately, as we age, the eye loses the flexibility which allows it to do this; thus, sights and target begin to grow fuzzy. There is a simple way to combat this by increasing your eyes’ depth of field (range of focus). If you look through an aperture or pinhole of the correct size, you will be able to see both sights clearly, and the target will be clearly defined as well.”
In addition to diopters for eyeglasses, Merit produces a variety of adjustable iris sight products for rifles, including the Variable Iris Aperature for AR15s. Visit MeritCorporation.com or call (518) 346-1420.
Cheaper Diopter from Lyman
If you can’t afford a Merit adjustable diopter, Lyman offers a similar all-plastic device for under $20.00. The Lyman Hawkeye Shooting Aid mounts directly to your eyeglass lens with a rubber suction cup. The diopter section is made of plastic, and aperture diameter is non-adjustable.
Though it is simple and inexpensive, the Lyman Hawkeye works for many shooters, if positioned properly. (Don’t think this is anything close to the Merit Diopter in quality though!) Currently, Cabelas.com has the Lyman Hawkeye on sale for just $12.88, item # IK-229094. MidwayUSA sells the Lyman Hawkeye for $18.99, item # 936878. One MidwayUSA customer reports:
“This thing really works! I have it on my shooting glasses, and it has made a significant improvement in my ability to keep the front sight and target in focus at the same time. If you are older and find that you are having a hard time keeping the target in focus over ‘iron sights’, then this may be the answer to your problem. Mine works equally well for both pistol and rifle, although I do have to change the device’s position on my shooting glasses when changing weapon types.”
Forum member Roy Bertalotto did a real nice off-set scope installation on a bolt gun to help a sight-challenged shooter. Roy explains: “A friend of mine shoots left-handed and has lost the sight in his left eye. I built him a scope mount so he can still shoot left-handed, but now use his right eye.” Roy’s fabrication work is impressive and we praise his efforts to help a fellow shooter stay in the game.
Roy bolted a plate to the existing scope rail on the top centerline of the Rem 700 action. This plate extends a few inches to the right. On the outboard end of the plate, Roy fitted a second scope rail, aligned with the bore. Weaver-based rings are then clamped to the outboard (right side) auxiliary rail.
Be Careful of Canting Issues with Offset Scope Installations
We’re pleased to see that Roy developed a solution for a shooter with an optical disability, but we want to stress that this is a specialized installation that can create some problems with point of impact shift if the gun is not maintained perfectly level. With the amount of horizontal offset (between the scope’s optical axis and the bore axis) built into this rig, if the rifle is canted, point of impact can shift rather dramatically. For a southpaw who is willing to adapt his/her shooting style, it may be better, in the long run, to learn to shoot right-handed if his/her right eye is the only good eye. Likewise, if a right-handed shooter can only see well through his left eye, he may benefit from learning how to hold the stock and work the trigger with his left hand. The shooter could still work the bolt with his non-trigger hand. Changing from right-hand to left-hand shooting (or vice-versa) may require a stock swap if the stock is not ambidextrous.
Burris Signature Rings in Stock Again
Because they allow you to mount a scope without markings, to “pre-load” elevation, and to correct for windage mis-alignment, Burris Signature Rings are extremely popular. So popular in fact that Signature Posi-Align Rings, particularly the “Zee” models for Weaver rails, have been back-ordered for months. Well, Signature Ring fans can now celebrate. Burris has recently shipped large supplies of Signature Rings, including the hard-to-find 30mm High Zees, to vendors across the country. If you’ve been waiting on these unique, affordable ring sets, get your orders in now.
A quick search of webstores shows that various models of Burris Signature Rings are available from all of the following vendors. NOTE: You may have to check with more than one vendor to get the exact size, height, and model you prefer. Inventories are subject to change on a daily basis. For example, Midsouth expects to get some more 30mm Signature Zee High rings in a couple days from now.
Bruno Shooters’ Supply: 1″ and 30mm Signature and Universal, 1″ Rimfire Signature Zee (Call for availability of sizes).
Eabco.com: Signature Zee 1″ and 30mm, Medium. (High — call for availability).

Articles by Jake Gottfredson in June Edition
The June Edition of GUNS Magazine contains two interesting articles by our friend (and AccurateShooter contributing writer) Jacob (“Jake”) Gottfredson. In the first article, Some Basic Riflescope Theory, Gottfredson identifies key principles of optics and shows how they apply to riflescope design and construction. He explains the term “Modulation Transfer Function” (MTF), and how this can be used to quantify both contrast and resolution. The author also explores the topics of color correction, chromatic aberration, and color fringing. Jake notes how color correction and focus precision are directly related. Jake also explains the difference between “clarity” and “resolution”. You can have a scope with good clarity but poor resolution or vice-versa. If a scope shows cloudiness it lacks clarity. If the scope can’t show a test grid in sharp focus, it lacks resolution. There are many other important insights Jake provides in this well-written article. We recommend you read the article and perhaps event print it out for future reference. If you are shopping for an expensive scope, Jake provides specific criteria by which you can judge a scope’s quality and repeatability.
600-Yard Playing Card Shoot — Tiny Target, Far Away
The second offering by Gottfredson in the June issue of GUNS Magazine, is an entertaining report about a 600-yard fun shoot using playing cards. Regular-sized 2.5″ x 3.5″ playing cards with a 3/4″ red dot are placed in the center of an 8.5″ x 11″ target sheet. To help aiming, the target sheets have a black ring about 5″ in diameter. After a sighter session, shooters are allowed 10 shots in 7 minutes from 600 yards. That’s a pretty tough challenge, but with a very accurate rifle, multiple card hits are possible. Jake reports that, at his “card shoot”, the two top competitors, Gary Chaney and Andrew Smith, each hit the card six (6) times, with Gary breaking the tie by hitting the 3/4″ red dot. If this sounds like fun, read the full story, and perhaps you can set up a similar match at your shooting club. Gottfredson even includes “10 Tips for Success” such as: “7. Shoot fast, trying to get all rounds downrange in the same wind. Stop when it changes and wait for it to return or hold off if it does not….”
In addition to two Gottfredson articles, the June Edition of GUNS Magazine has a helpful feature on the .243 Winchester by John Barsness. This provides a short history of the cartridge and Barsness discusses 6mm bullet options for hunters using the .243 to harvest game.
Idaho-based Hooker Tactical Safety & Defense has introduced an interesting new product that records images and video directly from your scope’s eyepiece, while still allowing the shooter to look through the scope. This system, dubbed the Third-Eye Sharp Shooter Eye-Cam (“Eye-Cam”), fits a small (8 oz.) video camera directly to the eyepiece of a riflescope. The Eye-Cam outputs live video to an iPhone, lap-top computer, or DVR. One can easily imagine the benefits of such a system for tactical and law enforcement marksmen, as well as game hunters. The key elements of a tactical engagement can be recorded, in real time, for later review and analysis. Or a hunter can record the results of his shot at a “once-in-a-lifetime” bull elk.
No Scope Modifications Required
The water-, shock-, and dust-resistant Eye-Cam is easily installed, with no modifications to your scope. Your scope’s zoom, elevation, and windage controls are not altered, and there are no changes to point of aim or point of impact. Unlike most other video adapters for scopes, the compact Eye-Cam does NOT block off the shooter’s view through the eye-piece. You can continue to use the scope normally. Hooker Tactical claims that the Eye-Cam does not distort or change the image viewed through the scope: “The clarity of the image… is as accurate and dependable as if the [Eye-Cam] was not there.”
Comment: Despite Hooker’s claims, we do suspect that the shooter would notice a slight reduction in brightness, and possible softening of focus at the edges — simply as the result of having another piece of glass placed between his eye and the scope’s actual eyepiece.
Sharp Shooter Eye-Cam Costs $2370.00
The Hooker Tactical Eye-Cam retails for $2370.00. It weighs just 8 ounces. Hooker offers a variety of flexible collars that fit over scope eyepieces, allowing the Eye-Cam to be adapted to most popular scopes. Eye-Cams ship with collar of choice, video cables, power cable, 9-volt power supply, and a handy storage pouch. Hooker Tactical stands behind its product with a 2-year unconditional warranty for repair and replacement “with proper usage”. For more info, visit www.HookerTactical.com, or call Hooker Tactical at (208) 527-3395.
Editor’s Comment: This is an intriguing product. While the Eye-Cam’s utility for hunters and law enforcement marksmen is obvious, we think the Eye-Cam could benefit competition shooters as well. The Eye-Cam could be particularly effective in shooter training, allowing a coach to see how well his student actually responds to hold-off calls and wind reads. The recorded video could also allow a shooter to review the effects of mirage as he proceeded through a course of fire. Video would also help a shooter develop techniques to hold the gun more steady and have a better follow-through.
While the Hooker Tactical Eye-Cam is very expensive ($2370.00), we think this is the predecessor of future products that will provide a variety of digital viewing/recording options for rifle shooters. As such products evolve (and become more affordable), we predict digital viewing technology will benefit precision shooters in many ways.
Low-Cost Alternative MeoPix iPhone Adapter for Spotting Scopes
The Third-Eye Sharp Shooter Eye-Cam costs a whopping $2370.00. For a tiny fraction of that price (about $70), Meopta’s MeoPix digi-scoping adapter lets you record stills and movies directly to an iPhone from a spotting scope.
Though you won’t be able to record what you actually see through your riflescope, the Meopta adapter will perform many of the functions of the Eye-Cam, such as recording the results of hunting shots — so long as you’ve got your spotter aimed at the target. Meopta’s simple but cleverly-designed MeoPix lets you easily record photos and videos from your range and hunting sessions. Anything you can see through the spotting scope can be captured by an iPhone. Hunters can capture images of distant prey, and record successful shots on game.
The MeoPix bracket is a universal-type device that was developed to allow the iPhone 4 or 4s models to interface with ANY binocular or spotting scope eyepiece (fitted cup required). When mated to a long-range optic, the MeoPix transforms a smart phone into a handy, long-range photo and movie capturing tool. The Apple-approved MeoPix adapter attaches securely to the iPhone. Meopta claims the MeoPix bracket ensures precise alignment and excellent image quality.
Eye-Cam Tip by EdLongRange. We welcome reader submissions.
Background: Last year, when Leupold introduced its 1.1-8x24mm FFP Mark 8 CQBSS scope at a whopping $3,999.00 price, jaws dropped in the shooting world. Folks rightly wondered whether anyone (other than Uncle Sam) would pay four grand for a small, compact scope, even if it did offer a broad magnification range and other innovative features.
U.S. Optics SN-8 Is Thousands Cheaper than Mark 8
Well U.S. Optics has just undercut Leupold by a couple thousand dollars, providing a much more affordable 1-8X option for tactical shooters and 3-gunners. If you were thinking about the Mark 8, you better take a close look at the new 1-8x28mm SN-8 from U.S. Optics. From what we can see, the SN-8 performs on a par with the Mark 8, plus it features a true 1X magnification on the low end — which is best for fast, both-eyes-open target engagement. The new SN-8 is offered in two models. The 1-8x28mm SN-8 Standard version retails for $1945.00, while the higher-end version with Red Dot-equipped eyepiece runs $2445.00, still substantially under the cost of Leupold’s Mark 8. These new SN-8s should start shipping in June, 2012.
New “Slim-Line” Hunting Scopes from U.S. Optics
For 2012, U.S. Optics is bringing out a series of compact, light-weight “Slim-Line” hunting optics: 1.5-6X, 1-4X, and 3.2-17X. Though they offer a significant weight-savings over typical hunting scopes, these new Slim-Line hunting scopes are built for hard use, and U.S. Optics backs them with an impressive, transferrable, “full lifetime” warranty. Prices start at $1100.00 and the Slim-Line Hunting scopes should hit the market in late March or April, 2012. We like what U.S. Optics is doing with this “Slim-Line” scope series. For daylight deer and varmint hunting, many hunters are better served with a compact 1.5-6X variable, than with a large, bulky high-power scope with a relatively small field of view.
At SHOT Show, in addition to its all-new SN-8, U.S. Optics also showcased its innovative dual-focal-plane tactical scopes. Offered in 1-4X and 1.5-6X, these offer the best of both worlds. The FFP reticle allows consistent ranging at all magnifications, while the Second Focal Plane functionality allows more precise aiming, since reticle line thickness does not increase as the magnification goes up.
While we were somewhat disappointed that we didn’t see many all-new precision rifles at Media Day 2012, there were plenty of new riflescopes on display. Among the most impressive new optics were rugged new high-zoom-range, First Focal Plane (FFP) tactical scopes from Hensoldt (Carl Zeiss), Leupold and Trijicon. These new scopes all featured fat tubes, compact overall length, and abundant elevation travel. These lastest top-end FFP tactical scopes offer as much as 26-power in a form factor not much bigger than a “normal” 4-16X scope.
New 3.5-26x50mm Hensoldt Was Outstanding
Hensoldt showcased a very impressive, prototype 3.5-26x56mm FFP tactical scope. Though this scope offers a whopping 7.4X zoom range and 26-power on top, this new Hensold is relatively compact. The reticle in these prototype versions was a very useful (and simple) milradian-based reticle that we hope Hensoldt retains in the production versions. The Hensoldt boasted an impressive 36 Mils of total elevation travel in two (2) turns of the turret. The new Hensoldt still shares the same superior glass and compact size that puts these scopes at the top of their class. We tested a prototype mounted to an Accuracy International AX 338. Expect the production version to be the same size and cost approximately $4000.00.
As you can see in the video, the new Hensoldt coupled with the new Accuracy Int’l AX in 338 Lapua Magnum worked very effectively at 900 meters in some tricky winds. This combination made it fairly easy to break clay pigeons on the bank at 900 meters. Off camera this combination continued to show great accuracy and very effective design features.
New Leupold MK-8
Leupold showed off a brand new MK-8 3.5-25x56mm with a Horus reticle and a beefy main tube. Again, this featured a lot of elevation in one turn as well as a pinch-and-turn locking turrets. This is a big leap forward for Leupold and we feel this will be well-received in the tactical world. Along with the new MK8, we also sampled Leupold’s new MK6 3-18x50mm. This shared similar features as the 3.5-25, and was incredibly compact as well. We expect the MK8 to sell near $4000 and the MK6 to be substantially less, likely under $3000 according to company reps.
Trijicon made a departure from their standard fare and jumped into the tactical scope world with a beefy Front-Focal Plane 3-15x50mm. This featured a well-executed MOA-based reticle and turrets with 30 MOA per turn (a Milrad version offers 10 Mils per turn). The Trijicon showcased the “short and fat” appearance that seems to be the latest design trend in tactical scopes. But though the Trijicon had a fairly short OAL (for its zoom range), it was still quite heavy at 47 ounces. The glass in this prototype version was disappointing for a scope that will retail in the $4K range. Reps told us the production version glass would be much improved. (It had better be, if Trijicon hopes to play in this stratospheric price range.)
It was apparent at Media Day 2012 that scope companies have worked hard to provide more features and more performance in their high-end tactical scopes. Consequently, the latest generation of scopes offer some very interesting and useful innovations — wider zoom range, more compact size, more elevation travel per rotation, and “goof-proof” turret mechanisms. We can only hope that, with more competition in this market, prices may become more reasonable. $4000 is an awful lot of money to pay for a scope.
Now through September 2, 2012, you can save big bucks on “factory blemished” Leupold VX-3, VX-L, VX-7, and Rifleman series scopes at MidwayUSA. Prices are slashed by as much as $260.00, and MidwayUSA is offering free shipping as well. These scopes may have minor cosmetic blemishes (small scratches, dents or ring marks) which do not impair function or reliability. All these “blem” scopes still carry Leupold’s full lifetime transferrable warranty.

Now Dial your elevation for 350 yards (from your come-up table).
