The movie “The Patriot” gave us the phrase “Aim small, miss small”. While that’s a good mantra, aiming strategies for long-range competition are a bit more complicated, as this article explains…
The The F-Class World Championships (FCWC) in Canada are just one week away. This August 11-17, the world’s top F-Class shooters will gather at the Connaught Ranges outside Ottawa, Ontario. Here are some tips that can help F-TR and F-Open shooters aim more precisely, and achieve higher scores. F-Class ace Monte Milanuk reviews reticle choices and strategies for holding off.
In our Shooters Forum, one newcomer wanted some advice on selecting a reticle for F-Class optics. He wondered about the advantage of Front (first) Focal Plane (FFP) vs. Second Focal Plane scopes and also wondered if one type of reticle was better for “holding off” than others.
In responding to this question, Forum regular Monte Milanuk provided an excellent summary of aiming methods used in F-Class. For anyone shooting score targets, Monte’s post is worth reading:
Aiming Methods for F-Class (and Long-Range) Shooting — by Monte Milanuk
F-Class is a known-distance event, with targets of known dimensions that have markings (rings) of known sizes. Any ‘holding off’ can be done using the target face itself. Most ‘benefits’ of Front (first) focal plain (FFP) optics are null and void here — they work great on two-way ranges where ‘minute of man’ is the defining criteria — but how many FFP scopes do you know of in the 30-40X magnification range? Very, very few, because what people who buy high-magnification scopes want is something that allows them to hold finer on the target, and see more detail of the target, not something where the reticle covers the same amount of real estate and appears ‘coarser’ in view against the target, while getting almost too fine to see at lower powers.
Whether a person clicks or holds off is largely personal preference. Some people might decline to adjust their scope as long as they can hold off somewhere on the target. Some of that may stem from the unfortunate effect of scopes being mechanical objects which sometimes don’t work entirely as advertised (i.e. one or two clicks being more or less than anticipated). Me personally, if I get outside 1-1.5 MOA from center, I usually correct accordingly. I also shoot on a range where wind corrections are often in revolutions, not clicks or minutes, between shots.
Some shooters do a modified form of ‘chase the spotter’ — i.e. Take a swag at the wind, dial it on, aim center and shoot. Spotter comes up mid-ring 10 at 4 o’clock… so for the next shot aim mid-ring 10 at 10 o’clock and shoot. This should come up a center X (in theory). Adjust process as necessary to take into account for varying wind speeds and direction.
Others use a plot sheet that is a scaled representation of the target face, complete with a grid overlaid on it that matches the increments of their optics — usually in MOA. Take your Swag at the wind, dial it on, hold center and shoot. Shot comes up a 10 o’clock ‘8’… plot the shot on the sheet, look at the grid and take your corrections from that and dial the scope accordingly. This process should put you in the center (or pretty close), assuming that you didn’t completely ignore the wind in the mean time. Once in the center, hold off and shoot and plot, and if you see a ‘group’ forming (say low right in the 10 ring) either continue to hold high and left or apply the needed corrections to bring your group into the x-ring.
Just holding is generally faster, and allows the shooter to shoot fast and (hopefully) stay ahead of the wind. Plotting is more methodical and may save your bacon if the wind completely changes on you… plotting provides a good reference for dialing back the other way while staying in the middle of the target. — YMMV, Monte
It’s good to see an ammo-maker step up to help the shooting sports. ELEY Ltd. has recently made significant investments in .22LR rimfire benchrest and competition segments within the USA. ELEY has partnered with the American Rimfire Association (ARA) and Professional Shooting League (PSL) to help promote and expand rimfire benchrest shooting, one of the fastest growing .22 LR rimfire competition disciplines worldwide. The ARA and PSL competitions are leading rimfire benchrest organizations within the United States. ELEY’s financial and logistical support will help the ARA and PSL grow the ranks of rimfire benchrest shooters.
Here’s a record-setting rimfire benchrest rifle owned by our friend Joe Friedrich who competes in ARA matches, primarily using ELEY .22 LR Tenex ammo.
ARA was started in April 1998 by a group of .22 LR shooters who wanted an organization for competitive .22 LR benchrest competition. In 2010, ARA started to transition to what it has become today, with the unique goal of continuing the vision of the ARA founders by providing an honest competitive organization that is true to .22LR shooting.
PSL was founded as a benchrest organization for the true precision shooting professional. With the growth of rimfire benchrest, there was a need to have a professional organization to which shooters would be compensated for their hard work, training and competition success.

Among .22 LR rimfire disciplines, benchrest shooting represents the “pinnacle of precision” — the very highest level of accuracy is needed to succeed. As such, ELEY has identified the need to help expand this growing sport. “This support by ELEY will help us bring .22 LR benchrest to the forefront of shooting competitions,” says Dan Killough, Director of ARA & PSL. “The expansion of [rimfire] benchrest … gives shooters a platform to enjoy and participate in rimfire competition that previously may not have been available to them,” stated Mike Corkish, ELEY Director of North America Sales.

2017 USA Smallbore Silhouette Champion | 2017 USA High Power Silhouette Champion
2017 Canada Smallbore Silhouette Champion
We don’t know if there is an official “Lady Rifle Shooter of the Year”, but we would nominate Silhouette shooter Cathy Winstead-Severin, based on her amazing shooting so far this summer. Cathy has delivered some truly dominant performances recently. In mid-July, competing at the Ridgway Rifle Club in PA, Team Lapua’s Cathy Winstead-Severin won the 2017 Hunter Rifle NRA Smallbore Silhouette Championship. Cathy scored 110/120 to win her 20th NRA National Silhouette title. Then Cathy went on to win both the Standard and Hunter High Power Rifle Silhouette National Championships.
With those victories, Cathy completed a clean sweep of Smallbore (Rimfire) AND High Power (Centerfire) awards — a stunning achievement. Cathy was using Lapua cases, VihtaVuori powder, and a combination of Lapua and Berger bullets to win her 21st and 22nd National Silhouette Titles.
More Glory Across the Border — Cathy Wins in Canada Too!
Less than three weeks after her wins at the USA National Silhouette Championships, Team Lapua’s Cathy Winstead-Severin ventured north and won the Canadian NFA National Smallbore Silhouette Championship. After the match she also hosted a very informative clinic for other shooters. Congratulations Cathy Winstead-Severin. You have our vote for Lady Shooter of the Year. We also thank Team Lapua for providing support for major Silhouette Championship events.
Creedmoor Sports has released a series of helpful “how-to” videos in its new InfoZone web page. In the latest InfoZone video Bill Gravatt shows how to seat bullets using L.E. Wilson Hand Dies and an Arbor Press. The basic process is simple, particularly with a micrometer-top seating die. That makes it easy to adjust and set seating depth. Before you start seating bullets, you want to adjust the height of the arbor so the stroke is appropriate to the height of your die.
Bill Gravatt Shows How to Use Hand Seating Dies — Creedmoor INFOZONE
ARBOR PRESS TECHNIQUE: When using an arbor press, smooth is good. You don’t want to slam the handle down quickly. Try to repeat the same motion each time. You can also experiment by seating the bullet part way, then rotate the cartridge (in the die) and do the final seating with a second stroke. If your arbor press has a force gauge, note both the max value of the gauge needle and how it moves as you seat the bullet. If the needle spikes too rapidly, or bounces back and forth irregularly, set that cartridge aside and/or mark it. You could have neck tension issue with that case or some other fault. You might even have a bad bullet. That’s rare, but can happen. The key to success is moving the press arm in a smooth motion every time, maintaining the same down-pressure with each cartridge.
Here Bill Gravatt Offers a Simple Tip for Adjusting Wilson Seating Dies
One of our Forum readers asked “How can I get a custom in-line seater for my new rifle?”. First, we would say that, if you are not shooting an unusual Wildcat, check first to see if L.E. Wilson makes a stainless Micrometer Seater Die for your rifle. These dies are a joy to use, and we’ve found the fit to be exceptionally good with many calibers. Typically priced from $90-$100, Wilson stainless micrometer-top seaters are available for dozens of cartridge types: .204 Ruger, 20 BR, .222 Rem, .223 Rem, 22 PPC, 22 BR, .22-250, .223 WSSM, 6 PPC, 6mmBR, 6XC, 243 Win, .243 WSSM, 25 WSSM, 6.5×47 Lapua, 6.5 Creedmoor, 6.5-284, 26 Nosler, .270 WSM, 7mm-08, .284 Win, 28 Nosler, 7mm RUM, 30 BR, 30 IHMSA, .308 Win, .300 WinMag, .338 Edge (and MORE).
If you do want a custom seater die, the process is relatively simple. Purchase a die blank from Wilson and have your gunsmith run the chambering reamer in. Forum member Gunamonth explains: “I start with a Wilson seating die blank. They’re available from Sinclair and other vendors. Just run the reamer in. For some of my rifles, where I wanted the stainless die with the micrometer adjustment, I bought a smaller die and had the smith ream it with the chamber reamer. That’s how I had my 6 Dasher and 6mm AI seaters made. With the Dasher I stared with a 6mmBR Micrometer die.”
SEATER STEM TIP: If, on your seated bullets, you are seeing a sharp line around the jacket near the ogive, you may want to smooth out the leading edge of the Wilson seater stem (see above left). Do this by putting a little lapping compound on one bullet and manually spin this around in the stem. Without much effort you’ll have a smooth bullet/stem interface.
Micrometer Top Add-on
We really like micrometer tops on a seating die. But what if Wilson doesn’t make a micrometer top seater for your chambering? Don’t despair, Sinclair Int’l sells a $39.99 micrometer top that can be added to Wilson standard seaters or to a custom seater die made from a Wilson die blank.
The F-Class World Championships (FCWC) in Canada are just one week away. This August 11-17, the world’s top F-Class shooters will gather at the Connaught Ranges outside Ottawa, Ontario. The vast majority of F-Open shooters will be running some kind of 7mm (.284 Caliber) cartridge, with the .284 Winchester, .284 Win Improveds, and 7mm RSAUMs being popular.
For those of you who plan to compete but who haven’t loaded your ammo yet, you may want to consider a very good 7mm match bullet from Sierra, 183 grain MatchKing (item #1983). We have found the 183gr MK, which comes “pointed” from the factory, to be very consistent in weight and base-to ogive measurement. Top F-Open shooters have told us that these bullets shoot exceptionally well, with minimal vertical dispersion at 1000. “Holding waterline” at long range is a reliable indicator that the BC is very uniform from bullet to bullet.
Sierra’s popular 7mm 183 grain MatchKing boasts an impressive 0.707 G1 Ballistic Coefficient (BC) at 2300+ fps. These bullets also have very consistent bullet-to-bullet BC, thanks to very uniform jackets and the tips being “pointed” at the factory. Sierra explains: “A final meplat-reducing operation (pointing) provides an increased ballistic coefficient for optimal wind resistance and velocity retention.”
Insight Into Sierra’s New 7mm MatchKing® by Sierra Product Development Manager Mark Walker
In late 2015, Sierra introduced a new 7mm MatchKing® bullet with a different type of ogive. As part of the introduction, I had the opportunity to use them at the F-Class Nationals held in Phoenix with very good results. While at the match, several people had questions about what exactly was different about the ogive on this bullet as opposed to our tried and true blended tangent ogive. So with that in mind, hopefully this blog will answer those questions.
In the past, Sierra has typically used a tangent radius ogive design on our MatchKing® bullets. This is one of the most forgiving ogive designs due to its ability to shoot extremely accurately when jumped, as well as, jammed into the rifling. On rare occasions, some of our MatchKing® bullets have used a secant ogive due to design constraints. However, this ogive is much more sensitive to changes in seating depth than the tangent ogive so we tend to shy away from it. When we decided to work on this new bullet, we wanted to see if we could improve on the accuracy of even our best shooting tangent ogive bullets.
One of the main factors of what makes an accurate shooting bullet is how it aligns itself with the bore when fired. If a bullet is slightly crooked when entering the bore, it will cause inaccuracy on the target. We set out trying to think of ways to make sure that the bullet has no choice but to align itself with the bore perfectly.
The first part of the barrel to encounter the bullet is the leade in the chamber. The leade is an angle that is cut into the leading edge of the rifling which helps to guide the bullet into the bore. To illustrate how current bullets fit into the leade, picture a cone (leade) with a ball (bullet) sitting inside it. The ball can be rotated in all directions and the cone cannot force the ball to orientate itself in any particular direction. When a bullet with a radius encounters the leade, it behaves in a similar way. Now this of course is a very simple example and of course advanced shooters use tight necks and brass that is perfectly formed to the chamber to make sure the bullet is aligned as perfect as possible. However, there is always a small element of misalignment that is possible even with all this precise preparation.
This brings us to the ogive on the new 7mm MatchKing®. We thought instead of using the typical ogive radius that can allow slight misalignment, why not use the same straight angle that is used in the chamber leade on the bullet ogive to force itself to always align with the bore? Imagine the same cone as above (leade) with an identical cone (bullet) sitting inside of it. The cone inside has no choice but to align itself perfectly with the cone that it is sitting in every time. With that in mind, we designed the area of the bullet which contacts the leade in front of the bearing surface using a straight 1 1/2 degree angle instead of the typical radius. Once past that area, we use a traditional high caliber ogive radius to provide a very sleek, high BC bullet.
I hope that explains our thought process behind this new bullet. In our testing, it is one of the most forgiving high-BC bullets we have ever made.
For affordable, low-recoil shooting fun it’s hard to beat a semi-auto .22 LR. While Ruger’s 10/22 is the most popular semi-auto .22 LR rifle, manufacturers are now offering AR-style self-loading rimfire rifles. We like AR-style .22LR rigs for Rimfire Tactical Matches and 3-Gun cross-training. With an AR-style rimfire rifle you can train with low-cost ammunition while enjoying the same ergonomics, controls, and sighting systems found on your centerfire ARs.
Smith & Wesson has upgraded its M&P 15-22, a fun rifle that we’ve praised in the past. The new M&P 15-22 Sport MOE SL model (Magpul Original Equipment Slim Line) features a more comfortable handguard, an improved grip, and an adjustable Magpul buttstock. The dedicated .22 LR M&P rifle retains the look and features of the company’s popular M&P rifle line, with the enhanced ergonomics of Magpul furniture. It’s offered with Flat Dark Earth (tan) furniture or dressed in matte black.
These rimfire versions of the AR-15 are excellent training tools for 3-Gun and service rifle shooters. You can practice with less expensive rimfire ammo, and save wear and tear on your centerfire ARs. Rimfire AR clones also work great for Rimfire Tactical Matches.
Field Testing the Smith & Wesson M&P 15-22
Smith & Wesson’s 15-22 is a nice little rifle. The M&P 15-22 is designed and built as a true .22 LR semi-auto from the ground up, with ergonomics (and most controls) identical to a centerfire M&P 15 rifle. NRA reviewer Colon Noir tested the M&P 15-22 and was impressed: “This gun is unbelievably fun to shoot. There is virtually no recoil. The non-existent recoil makes shooting fast a breeze. Yeah, the magazine is a little quirky… but in the grand scheme of things, this gun feels like a full-out AR-15. The M&P 15-22 makes for a great training companion. I would place this gun in the ‘Fun Box’ — it’s reliable enough that you can have a fun time shooting. I’m picking one up, because it’s guns like these that make you truly realize how fun shooting is.”
Here’s a Video Review of the M&P 15-22 by the NRA’s Colin Noir
The Kahles 10-50x56mm MOAK Long Range Riflescope By James Mock
The Kahles company of Austria is very old — dating back to 1898. With its long history, Kahles (two syllables, pronounced “Kah – less”) claims to be the oldest rifle scope manufacturer in the world.
What are the features of this scope that endear it to the discriminating long range shooter? First, it offers serious magnification — a true 10X-50X. It has a rather unique, centrally-mounted parallax adjustment control integrated with the elevation turret (i.e. they share the same axis). Included with the scope is a large ring which can be attached to the parallax control to facilitate adjustments without removing one’s head from the stock. Another unique feature is a small red and white pin that indicates how many revolutions one has made. If one red band shows, the scope is in the first revolution; with a one red and one white band, it is in the second revolution, and so on.
This scope has a 56mm lens, fast-focus eyepiece, and 1/8th MOA adjustments. This is an expensive scope ($2799.00 at Brownells), but there are no short cuts in its construction. The lenses have a proprietary “AMV” multi-layer coating that’s claimed to transmit almost 100% of the light. Also, there is an oil-phobic coating to resist scratches and contaminates such as oil or dirt from sticking to the lens. The scope is nitrogen-filled and features hardened steel mechanisms for adjustments.
Kahles 10-50x56mm Specifications:
Magnification: 10X to 50X
Objective lens: 56mm
Reticle: Second Focal Plane with MOA subtensions at 40X power
Tube diameter: 30mm, Nitrogen filled
Length: 16.9 inches
Weight: 31.4 ounces
Click Value: 1/8 MOA with 20 MOA per revolution
Range of adjustments: 5.3 ft. elevation/ 3.6 ft. windage @ 100 meters
Field of view at 100m: 8.7 feet @10X and 3.6 feet @ 50X
Parallax Control: Parallax ring is centrally mounted on same axis as elevation knob.
Parallax Range: 8m to infinity
Eye relief: 3.74 inches
I first got to test the Kahles in competition at a 300-yard match. The scope performed flawlessly with spot-on, positive adjustments. The central-mounted parallax ring worked perfectly, giving me parallax-free viewing with the ring set on 300. The quick focus ocular adjustment also brought the image into sharp focus. We had some mirage today, but I had no problem seeing bullet holes with the scope set at 40x. The MOA reticle served me well by allowing me to know how many 1/8 MOA clicks to adjust from the sighter target. I shot my Bartlein 1:13.5″-twist 6mm PPC barrel with N133 and Bart’s 65gr Super Man BT bullets. I shot 296-4X out of 300 possible. The 65gr BT seems to be at its maximum range and I was edged out by an excellent 297/?x by a 6mm Dasher. The scope certainly did its part, but I didn’t.
Shooting the Kahles 10-50X at 200 yards before 300-yard match. The quality of this scope makes zeroing it a pleasure. The clicks are positive and audible.
Kahles Performs Superbly Shooting the Square
With every new scope that I test, I shoot the “square” (a box test). This target below above has ½ inch squares and my aim point was the small square in the lower right quadrant. I shot two shots at it then moved the windage knob 5 MOA left and fired one. I then moved 5 up and fired again; moved 5 right and fired; followed by my final shot after clicking 5 MOA down. This last shot went through the hole made by the original two shots! That’s amazing. These were shot at 100m without wind flags.
Shooting with the Kahles in 600-Yard Competition
On the 3rd Saturday of the month, we shoot a 600-yard match consisting of four, 5-shot targets on the IBS target. The 600-yard match demands a scope that is very reliable and “spot on” in its adjustments. Since I don’t have a 600-yard range on which to zero, I simply zero at 100 yards and click up 11 MOA. At our matches we shoot steel gongs for sighting in. There is NO sight-in period before the match — all competitors are expected to be “on target” upon arrival. I had to put my faith in the Kahles click values.
Our 600-yard match was my first opportunity to use the Kahles at that distance. I shot the scope set at 40X all day. The crisp adjustments allowed me to get on target quickly and in the first match, I shot a respectable 48/50 with 1X. NOTE: for this 600-yard match I replaced my 6 PPC barrel with an 8-twist 6mm Dasher. I use 32.8 grains of Varget pushing a Bart Sauter 105gr rebated boat tail bullet.
Testing with Hood Scope Checker
Many shooters’ primary concern with scopes used for competitive shooting is their ability to hold point of aim (POA). To test the Kahles, I mounted it on the Hood Scope Checker alongside my 36X Valdada. By aiming both scopes at a given point on the paper and firing several shots, one can determine if either of the scopes’ POA is moving. I don’t have a “frozen” scope to use, but the Valdada has been rock solid for me during many competitions over the last eight years. Pictured below is the setup that I used to test the scopes.
It is a pleasure to test a scope of this quality. Everything works as advertised and there are no unpleasant surprises. Many premium scopes fail the POA test outlined above. If a scope holds point of aim, has repeatable crisp adjustments, and sharp clear images, what more could a person ask?
Summary: A Quality Optic with Great Performance
Although I am still evaluating this scope, there are some definite conclusions that I have reached. This scope is for the person who will not compromise his demands for quality, regardless of price. This is not the most expensive large scope on the market at $2799.00, but it represents an extremely high-quality product for those willing to pay a premium for a premium product.
Are there things that I do not like about this scope? Yes, the primary one is the weight (31.4 ounces). This is not a problem for those shooting long range with 17- or 22-pound limits, but the weight is a consideration for those shooting short range benchrest varmint classes (10.5 or 13.5 pounds). Also, I would appreciate screw-on lens caps rather that the large bulky cover. I know that both of these are minor things and do not reflect the quality of the instrument.
If I had to offer any type of critique, it would be for a lower price and lighter weight. I cannot fault the price or weight too much however because quality costs and the scope has large objective lens and a sturdy tube. All in all, I can recommend this scope without reservation to all who want the best and have the ability to pay for same. — James Mock

The Golden Eagle has earned good reviews from our Forum members. This scope features 60X max magnification, sharp lenses, low-dispersion glass, 1/8-MOA clicks, and a reticle that features MOA-based hold-offs and hold-overs subtensions are MOA-based at 40X magnification:
F-Class is a known-distance event, with targets of known dimensions that have markings (rings) of known sizes. Any ‘holding off’ can be done using the target face itself. Most ‘benefits’ of Front (first) focal plain (FFP) optics are null and void here — they work great on two-way ranges where ‘minute of man’ is the defining criteria — but how many FFP scopes do you know of in the 30-40X magnification range? Very, very few, because what people who buy high-magnification scopes want is something that allows them to hold finer on the target, and see more detail of the target, not something where the reticle covers the same amount of real estate and appears ‘coarser’ in view against the target, while getting almost too fine to see at lower powers.
Others use a plot sheet that is a scaled representation of the target face, complete with a grid overlaid on it that matches the increments of their optics — usually in MOA. Take your Swag at the wind, dial it on, hold center and shoot. Shot comes up a 10 o’clock ‘8’… plot the shot on the sheet, look at the grid and take your corrections from that and dial the scope accordingly. This process should put you in the center (or pretty close), assuming that you didn’t completely ignore the wind in the mean time. Once in the center, hold off and shoot and plot, and if you see a ‘group’ forming (say low right in the 10 ring) either continue to hold high and left or apply the needed corrections to bring your group into the x-ring.
It’s good to see an ammo-maker step up to help the shooting sports.
