Improve Bullet Seating Consistency — Lap Your Seating Stems

Erik Cortina bullet seating stem polish lap lathe

Here’s a simple task you can do that will give your seater die a more perfect fit to your match bullets. You can lap the inside of the seater stem so that it matches the exact profile of the bullet. This spreads out the seating force over a larger area of the bullet jacket. That allows smoother, more consistent seating, without putting dents, creases, or sharp rings in your bullets.

Erik Cortina bullet seating stem polish lap lathe

This process is demonstrated here by our friend Erik Cortina of Team Lapua-Brux-Borden. Erik, one of the nation’s top F-Class shooters and a skilled machinist, explains: “Here I’m lapping my new seater die stem with lapping compound. I chuck up a bullet in the lathe and lap the inside of the seating stem. I put lapping compound on the bullet and also in the stem. You can do the same with a hand drill and bore paste. You can see in the piture below how much contact area the stem has on the bullet after being lapped. This bullet is a Berger 7mm 180-grain Hybrid. ”

Q1: Is Lapping Seating Stems really necessary?

It can be helpful but it’s not necessary to make your seating stem an exact match to a bullet, particularly if you’re loading hunting or varmint rounds. But it is helpful to do some mild internal stem polishing. This should eliminate any ring (or dent) that forms on the bullet jacket during seating.

Sharp edges on a seating stem can cause a ring to be pressed into the bullet jacket — especially with compressed loads that resist downward bullet movement.

Q2: Is there any down-side to the process?

Not really. However, if you shoot many different bullet types for a particular cartridge, you may not want to conform the stem aggressively to one particular bullet design. Lightly lap the inside of the stem to remove burrs/sharp edges but leave it at that. A light lap will prevent a ring forming when seating bullets.

SSUSA Report on 2023 F-Class World Championships

F-Class World Championships south africa f-open f-tr

There’s a good report on the F-Class World Championships, held earlier this year in South Africa. The current issue of Shooting Sports USA (SSUSA), available for free online, features a detailed 6-page report on the F-Class Worlds. This major event features individual and team competitions. F-Open Team USA, shown above, won the F-Open World Championship, while the American F-TR team finished second to F-TR Team South Africa.

F-Class World Championships south africa f-open f-tr

F-Class World Championships south africa f-open f-trTeam USA won Gold and Silver at the 2023 F-Class World Championships in South Africa. With a strong, come-from-behind performance on the last day of the team match, The U.S.A. F-Open Team topped South Africa to win the F-Open Team Championship with a 3540-366V score (South Africa finished with 3535-374V — a “V” is like an “X” in the USA).

SSUSA Editor John Parker notes: “In March for this year’s F-Class World Championships held in Bloemfontein, South Africa, the United States sent a united F-T/R and F-Open team, shooting different guns, but with the shared goal of returning to America with as many team medals as possible. Our F-Open rifle shooters defeated South Africa on its home range for the first time in over two decades, capturing the F-Open Team Aggregate gold medal in a historic victory. Preceding the F-Class World Championships in Bloemfontein was the 2023 South African National Championship, where U.S. rifle shooter Erik Cortina [led] the F-Open leaderboard with a score of 687-65V. See Cortina, along with his 7mm PRCW rifle, on the cover.”

The F-Class World Championships were held March 26 – April 1, 2023 at the Genl De Wet Shooting Range outside Bloemfontein, South Africa. The multi-day individual matches had some tough conditions with strong, twitchy winds and rain delays. And the winds were challenging for the team matches as well.

Both F-Open and F-TR team matches were shot at multiple metric distances: 700m, 800m, 900m. The high-scoring American F-Open shooter was B. Kolodziej with 448-50V. His team-mate Todd Hendricks (444-53V) had the most Vs with 53.

Berger 6.5 Creedmoor Ammunition Shoots Great in PRS Rifle

Erik Cortina Berger Factory ammo ammunition OTM tactical PRS rifle MPA chassis Lapua brass

Is factory 6.5 Creedmoor ammunition good enough to win a PRS or NRL competition? The answer is a resounding “YES” if we’re talking about Berger ammunition. Produced with Berger match bullets and premium Lapua brass, this Berger 6.5 Creedmoor ammunition demonstrated excellent accuracy, impressive velocity, and very good ES/SD numbers. When tested at 1000 yards with an MPA-stocked PRS rig with Rem 700 action, this ammo showed just half-MOA of vertical, and produced a group that would have been a 50-1X in F-Class competition. That’s quite impressive for a PRS rig.

Erik Cortina Berger Factory ammo ammunition OTM tactical PRS rifle MPA chassis Lapua brass

This ammo test was performed by our friend Erik Cortina from Texas. The reigning SW Nationals F-Open champion, Erik is a top F-Class competitor who also shoots tactical matches (for fun and glory). A couple seasons back, Erik built a new 6.5 Creedmoor with a Remington 700 action. Though this rifle sports a top-shelf MPA chassis and premium Kahles scope, Erik calls this his “budget build” because it has a plain Rem 700 factory action rather than the elite Borden actions he normally runs. Erik’s actions of choice are the Borden Mountaineer for PRS and Borden BRM-XD for F-Class.

Erik Cortina Berger Factory ammo ammunition OTM tactical PRS rifle MPA chassis Lapua brass

Erik posted: “Shot my budget 6.5 Creedmoor … with Berger Bullets factory ammo. I shot five rounds over the chrono to get speed. I used BC info from the box and it all lined up properly. I adjusted my ECTuner to tune load and it took just 15 shots to get it shooting well. It’s simple with good components.”

This Berger factory ammo features Berger 130gr Hybrid OTM Tactical bullets. The Lapua 6.5 Creedmoor cases have a large rifle primer. You can see this ammo displays good velocity with Extreme Spread and Standard Deviation rivaling good hand-loads.

Barrel Tuner by Erik Cortina — Fits Behind Muzzle Brake
This rifle features a barrel tuner designed and crafted by Erik Cortina. You can the EC Barrel Tuner alone, or, as you can see, the EC Tuner can be fitted BEHIND a muzzle brake. Erik tells us: “The EC Tuner allowed me to tune the barrel to my ammo rather than tuning the ammo for barrel as is done when reloading. With the tuner, there is no need to try different brands of ammo as they can all be tuned to shoot as good as possible in my rifle.”

Saturday at the Movies: Erik Cortina Video Showcase

Erik Cortina saturday video f-open F-class reloading interviews

Erik Cortina is one of the world’s top F-Class shooters. Erik won the 2023 Southwest Nationals in F-Open Division, and he was a member of Team USA which won the F-Open World Championship in South Africa. And Erik also won the individual F-Open title at the South African National Championship which preceded the 2023 F-Class Worlds. Erik also has competed successfully in Long-Range and Precision Rifle matches. Along with his shooting skills, Erik is a respected video host. His Erik Cortina Video Channel now boasts nearly 500 videos, covering a wide range of shooting disciplines, along with reloading, load tuning, and other gun tech topics.

This Saturday we are featuring nine of Erik’s informative videos. These cover reloading techniques, marksmanship tips, and more. We start with two vertical-format “shorts”, both worth watching. In the first video you can see Erik nail five straight targets at 500 yards, with the last one a tiny square.

Barrel Break-in — Don’t Waste Barrel Life

A factory barrel can benefit from a break-in regimen. Some custom barrels shoot great from the get-go and don’t require elaborate break-in rituals. In this popular video, Erik explains how he determines the appropriate break-in procedure for his barrels: “Deciding if you need to break-in a barrel is not as easy as many think. In this video, I discuss the thought process I go through in deciding if I need to break in a barrel or not.”

Smallest 1000-yard Group Ever Caught on Camera

This 1000-yard group was NOT shot in a match, so it is not a record. But Erik shot a truly spectacular group during practice. This shows what modern F-class rifles can do with ideal conditions. Erik drilled five shots in 1.3″ inches, with 4 shots in under 1/2″ (see 1:15 – 2:20 time). And the first 3 shots landed right on top of each other (about 1/4″). Erik notes: “While shooting, I decided to set up my camera and record the screen on my phone so I could see the shots on my Electronic Target. To my surprise, the shots kept stacking up on top of each other. I had a 3-shot group under 1/4 inch! Most shooters would be happy with that at 100 yards, but this is at 1,000 yards!”

Common Sense Reloading

All novice reloaders should watch this video. Erik explains the three key items when reloading for accurate rifles. Erik explains: “We as humans have a tendency to complicate things, and reloading is no different. For some reason, we think that the more complicated it is, the better the end product will be. It doesn’t have to be that way, today I explain the three different things that must be in check to ensure you have a consistent and efficient load. Once you get these three things corrected, you’ll always have a good load.”

Team USA F-Open World Champions

The 2023 F-Class World Championships were recently held in South Africa. There were talented teams from many countries. With a strong, come-from-behind performance on the last day of the team match, The U.S.A. F-Open Team topped South Africa to win the F-Open Team Championship with a 3540-366V score (South Africa finished with 3535-374V — a “V” is like an “X” in the USA). Congratulations to the 2023 USA F-Open team, the new World Champions! Erik Cortina was a member of Team USA.

Stop Neck-Sizing Brass

With over 400,000 views, this is one of Erik’s most popular videos. Erik explains why it is NOT smart to neck-size only. For almost all rifle applications, you’ll get better case life and more consistent loads if you full-length size your cases. Full-length sizing also provides vital shoulder bumping, which is essential for proper case-feeding and smooth bolt closure. Proper full-length sizing will also help optimize ES and SD.

Precision Reloading Class at PRS Expo 2022

This 8-minute video records a seminar Erik conducted at the 2022 PRS Expo. In this segment, Erik explains the key elements of accuracy. He advises that the bullets are the most expensive element of each cartridge, and are critical to accuracy, so competitors should always buy the best — never attempt to cut costs on projectiles. CLICK HERE for PART TWO of Erik’s presentatiion.

About Erik Cortina Precision Products
Cortina Precision makes some of the best barrel tuners on the market. The EC Tuner was developed over a decade ago and has many championships under its belt. The EC Tuner was recently revamped and released as the EC Tuner V2. The V2 model employs a spring to maintain load on the tuner at all times and eliminate backlash. That helps with consistency. The EC Tuner V2 works well for centerfire, rimfire, and even air rifles.

Cortina Precision also offers the EC Tuner Brake. The Tuner Brake combines a barrel tuner with a muzzle brake. The EC Tuner brake greatly reduces recoil and allows you to tune your rifle to your load. These Tuner Brakes are a good choice for hunters and PRS/NRL competitors, as they work equally well with handloads and factory loads. For more information, visit ShootSmallGroups.com. – Erik Cortina

Erik Cortina Wins South African F-Open Title in Prelude to F-Class World Championships

F-class f-open world championships south africa

Congratulations to Erik Cortina winning the 2023 South African F-Open Target Rifle Championship with a Grand Aggregate score of 687-65X. This match was the domestic South African F-Class Championship, which preceded the 2023 F-Class World Championships which conclude on April 1, 2023.

The 86th South African Open Target Rifle Championships were held March 10-18th at the Genl De Wet Shooting Range in Bloemfontein, South Africa. The multi-day individual match had some tough conditions with twitchy, strong winds and rain delays.

Cortina, fresh off his first-place finish at the Southwest Nationals, used Lapua 6.5 PRC cases necked up to 7mm in his 7mm PRCW. He also took second in the President’s Cup, fourth in the Jack Mitchely Cup, and 11th in the Dalrymple Cup. Cortina is sponsored by Lapua.

“Traveling ten thousand miles and competing on an unfamiliar range is always nerve racking, but it’s comforting when the preparation pays off and things fall into place,” said Erik Cortina.

Cortina is currently in South Africa with the U.S. F-Class team competing in the 2023 F-Class World Championships. Eric Cortina finished 14th in the F-Open Division at the Worlds, which was won by B.J. Engelbrecht of South Africa.

2023 Southwest Nationals Match Report: F-Open, F-TR, Sling

Berger Southwest SW Nationals 2022 f-class f-open f-tr 1000 yards palma sling match Ben Avery Phoenix AZ

The 2023 Southwest Nationals (SWN) have concluded. Though there were very challenging wind/weather conditions this year, the 2023 SWN was a very successful mid-range and long-range event. There was some great shooting in F-Open, F-TR, and Sling divisions. We congratulate the 2023 Long-Range SWN Champions: Erik Cortina (F-Open, 1241-60X); Jeremy Newell (F-TR, 1221-49X); and Justin Skaret (Sling, 1233-50X). Notably, Skaret won Sling Division by 11 points — a big margin. SEE ALL 2023 Results.

The 600-yard champions were: Louis Buatt (F-Open, 600-39X), Luke Ramsey (F-TR, 596-31X), and Randy Teissedre (Sling, 597-33X). Buatt shoot a remarkable “clean” 600-yard match, not dropping a single point while amassing 39 “X”s. Superb performance by Louis!

Shown below is F-Open Long-Range (1000-yard) Winner Erik Cortina. Erik’s purple F-Open rifle was chambered for the new wildcat cartridge based on the 6.5 PRC necked up to 7mm. This drives high-BC 7mm Berger bullets at 2950 fps.

Review of Forster Co-Ax Press — Plus Cool Co-Ax Accessories

Co-ax Forster press
Forster Co-Ax Press
Lower image from Rex Roach Co-Ax Press Video Review on YouTube.

Forum member Erik Cortina has produced a series of YouTube videos about reloading hardware and precision hand-loading. Here we feature Erik’s video review of the Forster Co-Ax® reloading press. The red-framed Co-Ax is unique in both design and operation. It boasts dual guide rods and a central handle. You don’t screw in dies — you slide the die lock ring into a slot. This allows dies to float during operation.

Erik does a good job of demonstrating the Co-Ax’s unique features. At 1:00 he shows how to slide the dies into the press. It’s slick and easy. At the two-minute mark, Erik shows how sliding jaws clasp the case rim (rather than a conventional shell-holder). The jaws close as the ram is raised, then open as it is lowered. This makes it easy to place and remove your cases.

At the 5:20 mark, Erik shows how spent primers run straight down into a capture cup. This smart system helps keep your press and bench area clean of primer debris and residues.

While many Co-Ax users prime their cases by hand, the Co-Ax can prime cases very reliably. The priming station is on top of the press. Erik demonstrates the priming operation starting at 4:20.

Smart Accessories for the Co-Ax from Inline Fabrications
Forum member Kevin Thomas also owns a Co-Ax press, which he has hot-rodded with accessories from Inline Fabrication. Kevin tells us: “Check out the add-ons available from Inline Fabrication for the Co-Ax. I recently picked up a riser mount and a set of linkages for mine and love the results. The linkages are curved. When you replace the original straight links with these, the work area opens up substantially and the the press becomes much easier to feed.” CLICK HERE for Co-Ax Accessories.

Qualities of Winning Barrels — Brux Co-Owner Explains

brux barrels cut-rifle rifling Erik Cortina Krieger Ken Clemens

In this 54-minute video interview, Ken Clemens, co-owner of Brux Barrels, is interviewed by F-Class ace Erik Cortina for the Cortina Precision YouTube Channel. A lot of ground is covered, with many fascinating insights into barrel-making revealed. Watch and learn:

Interview with Ken Clemens, Co-owner of Brux Barrels

brux barrels cut-rifle rifling Erik Cortina Krieger Ken Clemens

If you are involved in competitive shooting, and especially if you compete in F-Class or long-range benchrest, we recommend you take the time to watch this interview, perhaps in a couple of sessions because it runs for a lengthy 54 minutes. Ken Clemens explains the important procedures that go into making match-grade, cut-rifled barrels. Ken also explains some factors to consider when choosing a barrel-maker and specifying length, contour, land/groove configuration, and twist rates.

For more information visit BruxBarrels.com, use the online PRICE ESTIMATOR, or call (608) 592-3324.

brux barrels cut-rifle rifling Erik Cortina Krieger Ken ClemensAbout BRUX Barrel-Making Methods
Brux starts with 4150 chrome-moly or 416R stainless steel double-stress-relieved bar stock — the best available. Barrels are bored with the Barnes gun drill, and reamed with an industry-standard Pratt & Whitney reamer. Brux uses solid carbide cutter hooks and employs special methods to achieve best results.

After the bore-cutting process is complete, each barrel is hand-lapped to high-precision standards. Multi-point inspections and meticulous hand processes (not possible in mass production) ensure extremely high quality. The Brux website says: “If there is the slightest deviation in surface finish or tolerance, the barrel is discarded.”

BRUX Specializes in Cut-Rifled Gun Barrels
Brux produces custom cut-rifled barrels, precision-crafted by professionals with extensive experience in both machine tools and competitive shooting. While Brux earned its reputation building great barrels for F-Class, benchrest, and long range competition, Brux also crafts hunting barrels. Brux states: “Hunters, big game and varmint, can benefit from the accuracy and dependability of a custom barrel made to your specifications.”

brux barrels cut-rifle rifling Erik Cortina Krieger Ken Clemens

BRUX Barrels’ Owners Are Competitive Shooters
Brux owners and machinists are shooters themselves. So they understand how important a truly top-quality barrel can be. Everything else about a rifle can be great, but you need a superb barrel to win at the highest level. Owners Ken Clemens (pictured above) and Norm Brux are both seasoned shooters with years of experience using their own products.

Made in the USA — About the Home of Brux Barrels
The Wisconsin River Valley near Lodi has a storied history of hunting and shooting. The glacier spared many granite escarpments, leaving secluded glens and a topography rich in soil and wildlife habitat, which attracted families with old-world values and skills. Many of their descendants turned raw steel and iron into the tools necessary for farming – and some evolved to precision tooling and making gun barrels.

F-Class Shooting at Bisley Range in the United Kingdom


F-Class Bisley England UK European Championships

F-Class competition is popular around the world, and the UK is a major center of F-Class shooting in Europe. The Bisley range is justly famous, with a long heritage of shooting competitions. This video features the European F-Class Championship held at Bisley in 2015.

Highlights from Day 1 of 2021 F-Class Nationals

In 2021 the NRA F-Class National Championships were held at Camp Atterbury, Indiana. Here is interesting footage from Day 1 of the Long-Range 1000-yard match. The video is narrated by our friend Erik Cortina, a top F-class shooter and member of Team Lapua-Brux-Borden. Erik has a popular YouTube Channel featuring interviews with many top shooters as well as reloading and tech tips.

WICKED WINDS — At Ben Avery with 18-30 mph Winds

Long-range F-Class shooters will tell you that the winds can be the biggest challenge in a match. And things can get pretty wild at times as the Ben Avery range in Phoenix, site of the 2022 NRA F-Class National Championships. In this video, shooters fight through extremely strong 18-30 mph winds at 600 yards. In these kind of extreme conditions, a major unexpected gust can send your bullet off-target.

Front Rest Options for F-Open (and Benchrest) Competition

If you are shopping for a front rest, definitely watch this comprehensive 42-minute video from start to finish. This is probably the most informative video about premium shooting rests available on YouTube. Top F-Class shooter and video-maker F-Class John covers a wide selection of front rests, with some observations about coaxial bipods as well. John covers the impressive new SEB NEO-X, the easy-to-transport SEB Mini-X, the excellent Rodzilla Rest, the innovative 21st Century Hybrid Rest, the sleek Italian Lenzi Rest. And at the end of the video John reviews the very affordable Caldwell Fire Control Rest ($204.99 on Amazon), explaining how it can be a decent choice for shooters on a limited budget.

Newbie Perspective — First Time Shooting F-Class

Saturday movies F-Class Australia Bribane Tikka T3 F-Open F-TRJust getting started in F-Class? Then you would appreciate this video, which covers the experience of an F-Class novice from Australia. The host of the video shot his first F-Class match at 600 yards with the Brisbane Mariners Rifle Club (BMRC) in Brisbane, Australia. He was using a Tikka T3 factory rifle with a $40 bipod. He enjoyed the challenge and had a good experience. This video shows that club-level F-Class can be fun, even with a modestly-priced factory rig. NOTE: This video is filmed indoors after the match, NOT on the lovely BMRC range shown above.

Reloading for F-Class — Interview with Erik Cortina

In this Precision Rifle Network video, Erik Cortina of Team Lapua-Brux-Borden covers the reloading process for his F-Class rifle. All phases of reloading are noted — brass prep, annealing, primer seating, precision powder measuring (to the kernel), and bullet seating. Erik also talk about load testing and use of barrel tuners. Erik produces the EC Barrel Tuner which is used by many top competitors.

Building a Modern F-Open Stock for Competition

In this video, our friend F-Class John explains the process for building two custom laminated stocks for his F-Open rifles. John selected handsome, highly-figured African hardwoods, which were then laminated into layers with purple-tinted heart-wood and dark Wenge wood stringers in the middle. The stock-maker then sliced the wood into layers (1:02) and then glued the layers together (1:40). After final cutting, the stocks are shown at 2:00, and then the video shows how the stocks received their final finish. Both stocks are fitted with the R.A.D. recoil-reduction system. See the bedding at 19:00 and the fully finished rifles at 19:12 with barreled actions fitted.

Crazy Small F-Class Group — Five Shots in 1.3″ at 1000 Yards

This video might just make you slap your forehead and say “that’s amazing!” During a practice session, Erik Cortina had a camera set up on the firing line along with a ShotMarker system on the target 1000 yards away. Erik recorded himself nailing a 1.3″ five-shot group, with four of the shots all touching in just 0.3″. The full group size, 1.3″, works out to 0.124 MOA — amazing accuracy for a big 7mm cartridge! And the four touching shots in 0.3″ represent an insane 0.029 MOA cluster! (1 MOA at 1000 yards is 10.47″.) As this was not shot in a competition, Erik’s 1.3″ group doesn’t count as a record, but it just shows how accurate a modern F-Open rifle can be when all the stars align for a talented trigger-puller.

Quit Neck-Sizing — Why It’s Better to Full-Length Size Your Cases

Full-Length Sizing Erik Cortina Neck Sizing Video

Why It’s Smart to Full-Length Size Your Brass

Commentary by Erik Cortina

Should You Full-Length Size Your Cartridge Brass?

Absolutely. Let Me Explain Why…

I have seen it time and time again, shooters on the line wrestling with their rifle trying to get the bolt closed while the wind is switching. They were too focused trying to get their bolt to close and getting their rifle settled back on the bags that they missed the wind switch. Bang… Eight! The straw that broke the camel’s back for me was at the 2017 Canadian Nationals. I was paired up with a young girl and she would try really hard to close the bolt on her rifle. The majority of the time she would get it to close, but often times she could not even get the round to chamber. She was focused on her rifle the entire time rather than on the conditions. When we completed our strings, she had five rounds that did not chamber our of 15! That is way too many!. I told her she needed to think about Full-length sizing with 0.002″ shoulder bump, or Controlled Full-length Sizing like I call it. I told her not to worry about losing accuracy. I told her that I full-length size all my rounds and asked if she noticed how smooth my bolt was and noticed my score. She said yes, they were both great!

Controlled Full-length Sizing Does NOT Harm Accuracy
I have found that Controlled Full-length Sizing does NOT hurt accuracy or shorten brass life. I find that I can focus much more on the conditions when I don’t have to think about chambering a round nor extracting it. It has become second nature. After firing, I keep my head welded to the stock, I open the bolt by placing my thumb on top of stock and rotating hand upwards. I reach in and retrieve spent case, place it back in ammo box, and pick up another loaded round and put in chamber. I verify conditions and when ready, I push the bolt in and close it with my index and middle finger.

With Controlled Full-length Sizing you “bump” the shoulder around .002″ for bolt guns.*

Whidden Gunworks DiesWhidden Full-Length Sizing Dies
by AccurateShooter.com Editor
For proper Full-length sizing, you want a quality die that’s a very good match to your chamber. For our project rifles we usually turn to Whidden Gunworks which offers both bushing and non-bushing FL dies. And if you want the hot new option, check out Whidden’s patent-pending, click-adjustable FL-sizing die. This gives instant, precise control over shoulder bump. It works great.

*With gas guns, such as the AR10, you may want to increase shoulder bump to .003″ or more. With some benchrest cartridges, .0015″ bump may prove optimal. But .002″ is a good starting point.

European F-Class Championships at Bisley in UK — F-Open Top 3

European F-Class Championships Bisley England UK

While American F-Class shooters have been getting ready for the 2022 U.S. F-Class Championships in Arizona next month, European F-Class aces were busy this month at the European F-Class Championships at the famed Bisley range in the UK. And a few Yanks were at Bisley as well. Our friend and Team Lapua-Brux-Borden member Erik Cortina shot great to take second place overall in the F-Open division, after Germany’s Alexander Kreutz. Past GB/Euro National League Champ Gary Costello took third in F-Open. We congratulate all three men. Erik had new hardware for this match — a prototype SEB NEO-X front rest. Erik told us: “I used the new SEB NEO-X. This was the first time using it in a match. It is truly amazing.”

British shooter and TargetShooter.co.uk editor Vince Bottomley sent this note:

“We were honored to have Erik Cortina over for the 2022 European F-Class Championship. In addition there were shooters from South Africa, Canada, Australia and of course Europe.

Erik acquitted himself amazingly well with second place overall in the F-Open category. The photo shows him with winner, Alexander Kreutz from Germany (center), and Brit Gary Costello in third place (right).

In addition to the usual ‘gongs’ the winner took home a Victrix F-Open gun plus a March scope.
