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

Ultimate Accuracy — The Best-Ever Five 5-Shot Targets

Gary Ocock Rail Gun Unlimited Target Visalia CA 6 PPC IBS NBRSA
Want to see the details? CLICK HERE to view full-screen photo.

Here are five targets, each with FIVE shots in essentially one hole. This amazing feat of accuracy was accomplished six years ago. We are reprising our report because this five-target Aggregate arguably represents the most impressive feat of 100-yard accuracy in the history of marksmanship on this planet.

Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s amazing 0.0840 Five-Target Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg will NOT be submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.

The argument can be made that this is the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time.

The Unlimited Benchrest Record That Will Never Be (Official)

Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:

When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.

GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.

LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets* seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.

Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.

Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.

Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.

Boyd Allen notes: The reason that the match was not sanctioned was that the sanctioning bodies like to have a month’s notice when scheduling a sanctioned match and because the range had been down for modifications and this was the first match after that, there was some question as to whether the work required to have stationary backers could be finished in time for the match. Rather than promise what might not be deliverable, the decision was made to hold the match under all of the usual competition rules as a non-sanctioned “fun” match. None of this diminishes Gary’s performance.

* Gary Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Shooting in Kneeling Position — Olympians Show Technique

Amanda Furrer USA Shooting

Bob Foth Paralympic coachWatch the video below to learn about the kneeling position, as explained by National Paralympic Coach Bob Foth and 2012 Olympian Amanda Furrer. Three-time Olympian and Silver Medalist Bob Foth details the proper techniques (both body position and gun-handling) for kneeling position shooting. Putting Foth’s coaching tips into practice, three-Position smallbore shooter Amanda Furrer demonstrates how to properly shoot from a kneeling position using a .22 LR match rifle.

Amanda, a member of the 2012 U.S. Olympic team, shows how to set up the right body position when kneeling, how to support the rifle, and how to relax breathing to steady the shot. This takes practice, but remarkable accuracy can be achieved from the kneeling position by top-level shooters. This is a great video, well worth watching.

The video uses superimposed graphics and diagrams to show rifle hardware/sights, and key aspects of the head position, sling set-up, and hold. If you are a position shooter, this is a “must-watch” video. Narrated by Olympian Bob Foth, it is very informative.
