Our friend Erik Cortina has built a new PRS/NRL rifle based on the new Borden Super Short 6 Action. This video show Erik’s first mag-feeding test with ten 6BR loaded rounds. You’ll see there is NO problem speed-feeding the short 6BR case. Erik tells us: “I removed the firing pin from bolt for safety. The magazine has not been modified in any way. I would say there is no need to do anything to it, she’s ready to run!” Impressive indeed.

4. Shooting USA — Texas Varmint Benchrest Match

Varmint Benchrest silhouette TexasThis episode of Shooting USA TV features long-range varmint silhouette competition in Texas. This discipline combine the pure accuracy of benchrest competition with the fun of knocking down critter targets. These are smaller than standard silhouettes, so it’s quite a challenge to hit them at 300 yards and beyond.

In this episode, host John Scoutten competes with his 6.5 Creedmoor PRS rifle. Most shooters use benchrest-grade rifles with premium front rests. NOTE: This video shows some top-flight benchrest rifles, and also covers the origins of benchrest varmint silhouette in Pennsylvania. There are even some AccurateShooter Forum members on screen.

5. Vickers Tactical — .308 Win Bolt Gun Vs. .308 Win Gas Gun

This interesting video from Vickers tactical compares and contrasts two tactical style rifles both chambered for the .308 Winchester. The test team compares functionality, accuracy, ergonomics, and versatility. Each platform has its advantages, as the video reveals.

6. Outdoor Life — The Best New Affordable Precision Rifles

This video showcases three modern tactical-style rifles suitable for the PRS Production (Factory) Class which is limited to $2000 for rifle alone, not counting optics (Rule 2.3.1). Outdoor Life Shooting Editor John Snow puts three capable rifles through their paces: Patriot Valley Arms John Hancock, BadRock Precision SouthFork, and Seekins Precision Havoc Bravo.

7. Aerial View of Deep Creek Shooting Range in Montana

The Deep Creek Range near Missoula, Montana, is one of the best 1000-yard ranges in the country. Many long-range benchrest records have been set in this scenic, tree-lined facility. Now, thanks to Forum member David Gosnell (aka “Zilla”), you can see Deep Creek from the air. David flew a camera drone over the Deep Creek Range, soaring from firing line to the target bay and back again. This video gives you a “birds-eye view” of one of America’s elite ranges.

8. Nat’l Rifle League — Intro to NRL22 Rimfire Tactical Matches

NRL22 is a great way to get into competition shooting with minimal expense. There are Five (5) classes: Open, Base, Ladies, Young Guns (8-16), and Air Rifle. Base Class is for the budget-minded shooter — the combined MSRP of Rifle and Optic may not exceed $1050.00 (so you could spend $550 on a rifle and $500 on a scope for example). That keeps the sport affordable. Open, Youth, and Ladies Classes have no price limits on Rifle and Optic. Visit NRL22.org to find an NRL22 match near you.

Neck-Turning Brass on Milling Machine with Erik Cortina

cartridge brass neck turn neck-turning milling machine Erik Cortina

Here’s the super-speedy way to turn case-necks. Our friend Erik Cortina figured out how to turn his match cartridge case-necks using his milling machine. Erik told us: “While in Raton, Mid Tompkins told me that he turns his brass on milling machine. He said he could do about 500 in two hours, so I decided to try it.”

Erik fitted a Don Nielson “Pumpkin” neck-turner to the mill, and he used a modified 21st Century case holder to secure the brass. As you can see from this video, Erik was very successful with the process. The tool spins at 1500 rpm, turning Lapua 6.5-284 cases that have been necked up to 7mm.

Video Shows Erik Cortina Neck-Turning Cases with Milling Machine:

Cartridge Brass: Lapua 6.5-284 necked up to 7mm
Lubricant: Lithium grease inside and outside of neck
Neck-Turner: Nielson Pumpkin running at 1500 RPM

It’s hard to argue with Erik’s results. Here are his turned Lapua cases, which have neck-wall thickness consistent to two ten-thousandths of an inch. Think you could do better turning manually?

cartridge brass neck turn neck-turning milling machine Erik Cortina

Some of Erik’s Facebook friends had questions about this process:

Q: Who makes the shell-holder?

Erik Cortina: I did! The shell-holder you can get from 21st Century. I Tig-welded a punch as a handle.

Q: I love the idea of working smarter not harder! Any galling issues? What are your mitigation techniques?

Erik Cortina: No issues. I use lithium grease in spray can. Makes a foam that I dip necks into.

Q: Shouldn’t either the case or the cutter be floating to allow most precise neck turning?

Erik Cortina: Up until [I tried this] I believed the same thing. I was going to build a floating case holder but decided to try rigid setup on a few cases before I built it. Results were great. Neck thickness doesn’t vary more than .0002″, which is same as when I was doing it with floating case holder on the lathe.

Q: Any problems with the Pumpkin changing the cut as it heats up?

Erik Cortina: No — there were no issues with that.

NOTE: Erik Cortina is a very skilled machinist who custom-crafted fittings used for this process. This kind of neck-turning with a milling machine may not be for the everyday hand-loader!

Nielson “Pumpkin” Neck-Turner

Don Nielson Pumpkin neck turning toolThe circular orange cutting fixture on Erik’s Milling Machine is a Don Nielson “Pumpkin” neck-turning tool. Don designed this tool to be used by hand or with power. The Pumpkin boasts an eccentric mandrel that allows the cut to be adjusted easily in precise .0001″ increments. Benchresters like this as it allows for very precise control of cut depth and neck-wall thickness.

Jason C., commenting on Erik’s YouTube video stated: “I have a couple of those too. Nothing cuts like a Pumpkin. [Don Nielson] made the best cutter tool ever.” These are still available if you ask around. The photo shows Don with a case-holder mounted to a power assembly. A talented machinist and tool-maker, Don has also been a successful short- and long-range benchrest shooter, who has won NBRSA 600-Yard Championships.

.284 Shehane — Winning Wildcat for F-Open Competition

7mm .285 shehane improved f-class f-open caliber cartridge chambering

High-BC 7mm Bullets7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.

The straight .284 Win is an excellent cartridge, quite capable of winning F-class matches. However, in most barrels, it can’t push the 180s at 2900-2950 fps velocity levels*. A lot of barrels will top out at about 2850 fps. That’s where the .284 Shehane comes into play.

The .284 Shehane is a slightly modified wildcat that retains the same 35° shoulder as the parent case. However, by blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc. With N560 or Reloder 17 you can go even faster.

Norm Harrold Won 2018 F-Class Open Division Nationals with .284 Shehane Rifle
F-Class Open F-Open Norm Norman Harrold Champion Championship 2018 Raton NM New Mexico 284 Shehane Berger Bullets

Norm Harrold (above) won the 2018 USA F-Class Nationals shooting a .284 Shehane. Norm’s F-Open rig features a McMillan Kestros ZR stock and Bartlein barrel chambered for the .284 Shehane, which has a bit more case capacity than a standard .284 Winchester. Norm loaded Berger 184gr 7mm bullets in Lapua brass. Norm revealed his load in an Erik Cortina YouTube Video.

F-Class shooter Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.

Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long-range round there is — bar none. Here is why:

You have to shoot a 30 Cal Magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight .284, the .300 WSM, and the .300 Win Mag with less recoil. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”

Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”

.284 Shehane Shines in 1K Benchrest Competition Too
The .284 Shehane has won in Benchrest as well as F-Class competition. In 2013, Henry Pasquet won the IBS 1000-Yard Nationals shooting a .284 Shehane. Henry’s Championship-winning rig is shown below. Note the 5″-wide fore-end which is not legal for F-Class. Henry also runs a combo tuner/muzzle-brake.

Amazing Accuracy When Fire-Forming .284 Shehane

7mm .285 shehane improved f-class f-open caliber cartridge chambering

If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains: “Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.”


*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s”.

Ireland vs. USA — 2019 Creedmoor Cup Competition

Arizona Ireland USA American Creedmoor Challenge Cup rifle competition

The Creedmoor Cup is an historic challenge match between American and Irish marksmen. The first match was held in in 1874 between American and Irish Teams in Creedmoor, New York. (Read Match History). The Match was revived in 2011 and is now held every four years.

In 2019, the match was held this week at the Ben Avery Range in Arizona, following the Berger Southwest Nationals. It proved to be a great match, with Team USA coming out on top. Erik Cortina stated: “What a great experience this has been. Team USA won the 2019 Creedmoor cup vs Ireland. It had been over 100 years since match was shot in the United States. Glad to see this tradition continue.”

Not Your Typical Warm Arizona Days at Ben Avery
There were variable conditions at the match — first easy, then tough. USA Captain Phil Kelley reported: “On Day 1 of the 2-day match, things started good then got tougher. The morning and 800-yard line saw 34° and light winds leading to high scores.

That changed as the 16-shooter teams made their way to the 900-yard line as sun, moderate wind and building mirage hit the range providing more challenging conditions.

After an excellent lunch both teams were in for a challenge. Winds of 12-16 mph with constant angle changes and surging mirage made communications and coordination among five coaches critical. The wind chill also dropped as teams stayed on the line for the majority of allotted time.”

The First-Ever Creedmoor Challenge Match in 1874
The Irish International Shooting team arrived in New York on the 16th of September and proceeded to “take in the sights”, which was understandable, before some practice at the Creedmoor range. On September 26th they presented themselves for the match with confidence and in high spirits. The crowds that day were reported to be between 5,000 and 10,000 strong, which showed the huge support already growing for the fledgling sport in America.

The course of fire was 15 shots to each man at 800, 900, and 1000 yards. Unfortunately, the details of each mans scores at the individual distances have been lost to time but we do know that the Americans were well ahead after the 800-yard shoot. The Irish then caught up after the 900-yard and finished the 1000-yard shoot ahead by 1 point. The Americans still had one man left to shoot and it came down to his very last shot with which he scored a 4 giving the American team the win over the Irish by 3 points.

Post-Competition Camaraderie and “Craic” at the Pub
“Craic” is an Irish term referring to positive interaction among people through conversation, stories, and music. The Craic was strong after the 2019 Creedmoor Match.

Desert Sharpshooters posted: “The ‘Craic’ is amazing tonight with the Irish rifle team to finish the Creedmoor. Thank you to the USA team members that came out tonight to show the Irish a good time. This is truely what the Creedmoor Cup is about, Friendship and good times.”

‘Quit Neck Sizing’ — Cortina Explains Full-Length Sizing is Better

Full-Length Sizing Erik Cortina Neck Sizing Video

Our friend Erik Cortina is at Raton, NM this week at the F-Class Nationals. When he’s not shooting (or working) Erik produces YouTube videos. One of his most popular videos explained why you should full-length size cartridge brass. In no uncertain terms Erik says: “Quit Neck Sizing!!!” Watch the 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!

Full-Length Sizing Erik Cortina Neck Sizing Video

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.

Make Your Own Threaded Case for Measuring Length to Lands

Hornady Stony Point Tool OAL O.A.L. gauge bullet seating length ogive checker

In this video, Forum member Erik Cortina shows how to create a custom modified case for use with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). While Hornady sells modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case*. And even if you shoot a standard cartridge such as the .308 Winchester you can get more consistent measurements if you make a custom modified case from a piece of brass fired in your chamber.

The process is straight-forward. Take a piece of brass fired in your chamber and full-length size it (with about .002″ shoulder bump). Then you need to drill out the primer pocket. Erik uses a mini-lathe for the operation, but this general process can be done with a drill press or other tools. Erik shows how to do this with a 0.290″ HSS (High Speed Steel) drill bit on a mini-lathe. After drilling the hole comes the tricky part — you need to tap the case with the precise 5/16″ x 36 threads per inch (tpi) right-hand thread that matches the male thread on the O.A.L. Gauge. This 5/16″ x 36 tpi tap is pretty uncommon, but you can order it from Amazon.com if you can’t source it locally.

Hornady Stony Point Tool OAL O.A.L. gauge bullet seating length ogive checker

If you use a mini-lathe, Erik suggests loosening the tailstock slightly, so it can float while cutting the threads. Erik also says: “Make sure you get the tap on pretty tight — it’s going to want to spin.” Erik turns the case at about 100 rpm when tapping the threads. Once the case and tap are rigged, the actual tapping process (see video at 6:00) takes only a few seconds. While the mini-lathe makes the tapping process go more quickly, the threading can also be done with other systems.

TIP: Don’t just make one modified case, make three. That gives you one for your range kit, one for your home reloading bench, plus a spare (since you WILL eventually lose or misplace one).


Here’s the Stuff You Need

Hornady Stony Point Tool OAL O.A.L. gauge bullet seating length ogive checker

5/16″-36 TPI Threading Tap
The required thread is somewhat uncommon. You need a 5/16″ – 36 tpi Right Hand Thread Tap. If you can’t find it locally, Amazon.com carries the correct tap. Erik notes: “The 5/16-36 tpi tap is not a common size. I think Hornady did this on purpose to make it more difficult for the average guy to make his own modified cases.”

0.290″ Drill Bit
Erik uses an 0.290″ HSS “L” drill bit. (This “L” Letter Gauge code designates a 0.290″ diameter bit). A close metric equivalent would be 7.3 mm (0.286″). Erik says: “A 9/32″ drill will also work but it will be harder to run the tap in since the hole will be .281″ instead of .290″ with the Letter Gauge L bit.”

Tips for Using O.A.L. Gauge with Modified Case
We’ve noticed that many folks have trouble getting reliable, consistent results when they first start using the Hornady O.A.L. Gauge (formerly the Stoney Point Tool). We’ve found this is usually because they don’t seat the modified case properly and because they don’t use a gentle, consistent method of advancing the bullet until it just kisses the lands.

Here is our suggested procedure for use the O.A.L. Gauge. Following this method we can typically make three of four measurements (with the same bullet), all within .001″ to .0015″. (Yes, we always measure multiple times.)

1. Clean your chamber so there is no build-up of carbon, debris, or lube. Pay particular attention to the shoulder area.

2. Screw the modified case on to the O.A.L. Gauge. Make sure it is seated firmly (and doesn’t spin loose). Note, you may have to re-tighten the modified case after insertion in the chamber.

3. Place your selected bullet so that the ogive (max bullet diameter) is behind the case mouth. This prevents the bullet from “snagging” as you insert the tool in the action.

4. Insert the O.A.L. Gauge into your chamber smoothly. Push a little until you feel resistance. IMPORTANT — You need to ensure that the shoulder of the modified case is seated firmly against the front of your chamber. You may have to wiggle and twist the tool slightly. If you do not have the modified case seated all the way in, you will NOT get a valid measurement.

5. Advance the bullet slowly. (NOTE: This is the most important aspect for consistency!). Push the rod of the O.A.L. tool gently towards the chamber. DON’T shove it hard! Easy does it. Stop when you feel resistance.

6. IMPORTANT. After gently pushing on the rod, give the end of the rod a couple forward taps with your finger. If your bullet was slightly skewed, it may have stopped too far back. Adding a couple extra taps will fix that. If the bullet moves after the taps, then again push gently on the rod. NOT too much! You just want to push the bullet until it just “kisses” the lands and then stops. Do NOT jam the bullet into the rifling. If you do that you will never get consistent results from one measurement to the next.

* For a $15.00 fee, Hornady will make a custom modified case for you if you send two fired pieces of brass. Send two fired cases and $15.00 check to: Hornady Manufacturing, Attn: Modified Cases, 108 S. Apollo St., Alda, NE 68810. More Info HERE.

Three Great How-To Videos from Erik Cortina

Erik Cortina Video SEB Rest NEO Upgrade coaxial Lambang Modified Case Hornady Length gauge RCBS Chargemaster

Erik Cortina is one of the nation’s top F-Class shooters. A member of Team Lapua-Brux-Borden, Erik has been a top performer at National and World F-Class Championships. Erik is also a very smart guy and a skilled toolsmith who has upgraded his shooting equipment in interesting ways. Today we feature three “How-To” videos from Erik. These show how to upgrade a SEB Coaxial Rest, how to improve the performance of an RCBS Chargemaster, and how to create your own Modified Case for measuring length to lands.

1. How to Upgrade your SEB Co-Axial Joystick Rest

Erik Cortina Joystick SEB Rest accessory f-class feet holder

Joystick (coaxial) rests are used by top shooters in benchrest and F-Open disciplines. With coaxial rests, you can adjust both vertical and horizontal aim instantly in one fluid movement — there are no mariner wheels to spin or knobs to turn. Just gently stir the joystick to move up, down, or sideways. Erik Cortina explains: “If you want to get into F-Class (Open) and want to win, you should get a SEB rest. SEB makes an excellent product, but the one thing we upgrade automatically … is adding the F-Class feet. These have a bigger footprint and a spike on the bottom [so you can] dig the feet into the ground and make your rest a lot more stable.” In this video Erik installs a set of Blake Machine Co. F-Class feet. These feature a set-screw, so they are easy to attach and then remove for travel (no Loctite!). “Simple yet effective” declares Erik.

In the second half of the video (starting at 5:30), Erik installs a Dan Bramley Joystick Holder. This features two clamp-on cradles that hold the joystick crosswise below the top (see photo). This handy accessory ensures your handle always remains with the rest (and doesn’t get left at home when you travel to a big match). This joystick holder has been popular with competitors. Erik says, “The Bramley Joystick holder is $60.00 — money well spent.” To order, email Dan at dbramley [at] yahoo.com.

2. How to Make a Modified Case for the Hornady OAL Tool

Hornady Stony Point Tool OAL O.A.L. gauge bullet seating length ogive checker

In this video, Forum member Erik Cortina shows how to create a custom modified case for use with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). While Hornady sells modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case. And even if you shoot a standard cartridge such as the .308 Win, you can get more consistent measurements if you make a custom modified case from a piece of brass fired in your chamber.

3. How to Make the RCBS ChargeMaster 1500 Work Better

Erik Cortina has been fiddling around with his RCBS ChargeMaster and he discovered something interesting. Through a series of tests he determined that the ChargeMaster dispensed slightly more precise charges when he trickled the last few 10ths of a grain on to the RCBS pan. Erik wasn’t expecting this result, but he confirmed there may be a slight benefit to this trickling method (as opposed to allowing the ChargeMaster to dispense the full charge). You can see Erik’s test procedure in this video:

We should note that Erik’s preferred method of weighing powder is to first dispense a slightly lower charge with the RCBS, transfer the pan to a laboratory-class Sartorius magnetic force restoration scale, then trickle up with his Omega (Dandy Products) Powder Trickler. However, if you don’t have a $800+ laboratory-grade scale, you might just try trickling on to the ChargeMaster pan.

MORE INFORMATION: We have published a more lengthy Bulletin Article that covers Erik’s Chargemaster Performance Findings in greater detail. That article has more photos plus a clever, bonus “Beep Defeat Tip”. If you own a Chargemaster, we recommend you READ the Full Article.

Going Grendel — Erik Cortina Converts AR15 to 6.5 Grendel

6.5 Grendel AccurateShooter.com cartridge Erik Cortina

Here’s an interesting project — using a second-hand barrel to upgrade an AR15. Our friend Erik Cortina decided to make his AR15, originally chambered in 6.8 SPC, into a 6.5 Grendel. Erik acquired a “pre-owned” 6.5-06 match barrel through our Shooters’ Forum. Erik inspected the barrel with a bore-scope and confirmed it was in good shape after the first few inches (past the chamber).

Erik Cortina barrel 6.5 Grendel

The 6.5-06 barrel had more than enough length, so he trimmed off the chamber end, then contoured the barrel to fit his AR15. This is a smart way to upgrade a gun without spending $350 or more on a brand new barrel.

In the first video, Erik explains the process of converting his 6.8 SPC AR15 into a 6.5 Grendel: “I take the upper completely apart and pull barrel off which will be used to take dimensions for new barrel. The new barrel will be turned from an old competition heavy barrel. All the barrel reaming will be done using JGS reamers. I will also use JGS reamers to make a seating and F/L sizing die.”

In the second video, Erik contours the “pre-owned” barrel to fit his AR. He uses an old bolt-action 6.5-06 competition barrel and cuts it to 17″ long and contours it to fit his AR-15. The barrel is turned down on a manual lathe to .750″ outside diameter for the majority of its length in order to fit the gas system barrel block that is made for a .750″ barrel. After contouring, the barrel will be threaded and chambered.

Stop Neck Sizing! Why You Should Full-Length Size Your Brass

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 out 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.

F-Open Nat’l Champ Talks Wind Reading and Cartridge Choice

Lodi Wisconsin F-Class National Championship Ian Klemm Robert Mead Jay Christopherson F-TR F-Open Borden Brux
“A big congratulations to Bob Mead (1582-68X), who utterly destroyed the competition in tricky wind conditions to take the Gold.” — Jay Christopherson, 2017 F-Open Nationals Second Place.

In this 15-minute video, Team Lapua’s Erik Cortina interviews Robert Mead, the 2017 LR F-Open Champion. Robert (Bob) discusses his wind reading techniques with Erik, and the newly-crowned F-Open Champ explains how to set up a reliable wind zero. Bob also discusses cartridge choices in F-Open. He admits the straight .284 may be the tightest grouping 7mm cartridge, but he has used the 7mm RSAUM for a decade now. He believes the RSAUM may the best cartridge for 1,000 yards in 7mm, all things considered (grouping ability, ballistics): “To me it’s a light magnum, it’s capable of high speed, yet burns less powder than your regular magnums. [But] it’s a finicky cartridge — you’ve got to do a fair amount of load development.”

Every serious F-Class competitor should watch this video start to finish:
