Future Tech? 3D Printed Metal Rimfire Receiver Made in NZ

Rimfire .22 LR Receiver action 3D Printer Printing custom action New Zealand 40X PT&G

Here’s something truly innovative — a 3D-printed metal rimfire receiver!

Forum member Marcos G. (aka MFP_BOP) has designed and created his own rimfire action. But it’s not machined or forged. This new action was created with a 3D sintered metal printer. A 3D modeler by profession, Marcos has the requisite skill set and access to a very high-tech (and expensive) metal printer. As printed, the actual receiver is shown below. It has just been sent out to be age-hardened to 40 HRC, after which final finish work (e.g. cleaning up tenon threads) will be done. To learn more about this 3D-printing project, read this FORUM Thread.

Rimfire .22 LR Receiver action 3D Printer Printing custom action New Zealand 40X PT&G

When most of us think of 3D printing, we think of small plastic parts — nothing as strong as steel. But there are 3D printers that employ sintered metal to build complex metal components. Marcus says the receiver he’s created should have “stated yield and tensile strength similar to investment casting.” The material used for the action is 15-5 PH® Stainless Steel (in sintered form).

The action was designed to use a PT&G 40X rimfire bolt. Marcos notes that “There is an extraction cam inside of the action, something that would be very hard or impossible to do by regular machining and/or EDM.”

Born in Brazil, Marcos now lives in New Zealand. He tell us that: “New Zealand is a very gun-friendly country. I just need my A-CAT license to make [a receiver.]” So there are no special legal restrictions (as might apply in the USA). The printer is EOS270 laser metal sintering machine. Marcos says: “The current price for one of those machines is in five figures, but I am 99.99% sure that in 5-7 years this technology will be readily available to anyone.”

As designed, the receiver was 1.4″ in diameter. Marcos reports it came out of the printer at 1.403″. The designed boltway is .690″ and it came out .687″. Marcos notes: “I haven’t noticed any warping. The threads are rough, really! Interior and exterior finishes are really good though, probably because of the way it’s been printed: upside down (must have gone through tumbling afterwards). I will have to run some taps and single-point-cut the tenon threads to clean them up.”

Marcos says the actual printing process took a lot of time: “I should have asked how long it took to be printed!” But consider this, the 7″-long receiver is created in layers only 20 microns thick, so you can understand why the process took so long.

Reasons to Print a Rimfire Receiver
Marcos 3D-printed his own action basically to save money: “Some may be asking why I printed this receiver. Here’s a little history… I tried different ways to bring a Stiller 2500X action into New Zealand. The final price to my door was NZ $3000.00 (about $2195.00 USD). Designing and making one would be way cheaper, but I felt nobody here could machine the internal abutments with precision. Also printing was still a little cheaper and printing offered the chance to put in it all details I wanted — such as M4 threads, internal cam, and fillets.”

Thunder Downunder — New Zealand North Island Rifle Match

Clevedon New Zealand club match F-TR FPR F-Open Sling Target Rifle

Clevedon New Zealand club match F-TR FPR F-Open Sling Target RifleNew Zealand is a beautiful country with rich, verdant green hills, snowcapped Southern Alps, thousands of miles of coastline, and abundant, unspoiled nature. Here’s quick look at what it’s like to shoot in New Zealand, aka Aoteoroa, the Land of the Long White Cloud.

New Zealand has a long, proud heritage of Marksmanship, and the little island country has hosted major international matches in recent years. This report is from a regional club match hosted at the Clevedon Rifle Club in the North Island, south of Auckland. The club website says: “At Clevedon we shoot from 300 yards back to 1000 yards, mainly with single-shot target rifles in any caliber up to 8mm. There are several styles of target shooting, Target Rifle with open sights and supporting the rifle with a sling, F-Class where a rest and telescopic sights are used and Hunter Class where standard hunting rifles with a support are used. The shooting season goes from September until May. The range is situated on a working farm so changes to the club program happen around hay making [and other farm activities].”

These photos are from the Clevedon Rifle Club in Clevedon NZ (North Island), south of the Auckland metropolitan zone. The range is on a working farm near the Clevedon Scenic Reserve and Hanua Ranges Regional Park. These images were posted on the New Zealand NRA Facebook page.

Sunshine Down Under with Competition at 300, 500, and 600 Yards
The Kiwi club reports: “Round 5 of the Clevedon Club Championships was completed today over 300, 500, and 600 yards in fine, sunny conditions. This is the finish of the short ranges with the Long Range [matches set for] next Saturday. Being Easter weekend we had a great turn out with 28 shooters, still managed to get people shooting on the wrong target. The four divisions were F-Open, F-TR, FPR (Field Precision Rifle), and Target Rifle. Next Saturday, 10 April, shooting is over 800, 900 and 1000 yards, last round of the Club Champs, set up from 8:15 and shooting to start at 9am At 800 yards.”

What is FPR Class?
The FPR (Field Precision Rifle) class is for shooters with muzzle brakes or suppressors (not allowed in normal F-Class rules), and are generally bolt-action rifles purchased from retail stores. Commonly used are the Ruger RPR, Remington 700, and Savage variants. EDITOR: We would like to see the FPR Class get started here is the USA. It seems like a good way to expand participation with more affordable rifles.

Sunday GunDay: English Emily’s 6mmBR Benchrest Rifle

Emily Benchrest 1000 yards England UK schoolgirl Kales Scope Light Gun Record
Emily was just 8 years old when this photo was taken back in 2017. She’s now 11 but still enjoying shooting. Emily has won many awards — including a screamer at 1000 yards — and her accomplishments have not gone unrecognized.

English Emily and Her Record-Breaking 6mmBR Stolle

Report by Vince Bottomley
Turning back the clock a decade or so to 2006 and Accurateshooter’s Gun of the Week #71 you will see my smiling face and my 7mm WSM BAT which had just set a new UK Light Gun record for 1000-yard benchrest with a 5-shot group measuring 2.67 inches. That record has now been broken — sadly not by me but by Emily’s Grandfather with a gun I built for this talented schoolgirl. Here’s the story of the precocious Emily and her record-setting rifle…

In 2006, when I set the record, young Emily Lenton wasn’t even born but, a couple years later she arrived – into the shooting-mad Lenton family. Both father Bruce Lenton and Granddad Tony have represented their Country at European and World Benchrest Championships and it was no surprise to see Emily, at just eight years old in 2017, shooting in her first 1000-yard benchrest competition.

Emily Shoots 6mmBR Heavy Gun at 1000 Yards.

Recoil is always going to be a problem for a very young shooter, so Emily’s first bench-gun was Granddad’s 1000-yard Heavy Gun chambered for the 6mmBR cartridge. It hardly moves when Emily pulls the trigger and she soon became a serious contender. [Emily was 8 when she started, and is now 11 years old.]

Under her father Bruce Lenton’s careful supervision, Emily loads all her own ammunition.

Of course, she wanted her own gun and who better to ask to build it than the current record holder — me of course! Emily chose a Stolle action RBLP as this was to be a 17-lb Light Gun, bedded into a UK-made Joe West laminate stock. The barrel was a heavy-profile 1:8″-twist Krieger chambered in 6mm BR Norma (6BR) with a ‘no-turn’ neck (reamer from Pacific Tool & Gauge) and fitted with a UK Tier One muzzle-brake.

Emily’s Light Gun begins to take shape…

It was down to Granddad to help Emily with load-development and of course, he could also shoot it in competition — after all Emily had just about shot-out Granddad’s Heavy Gun with a full season of rapid-fire 10-shot groups!

Granddad Tony gets ready to shoot Emily’s gun.

Then something happened – Granddad went and broke my ten-year old record with Emily’s gun! Well, I suppose there was some consolation — at least I’d built the record-breaking gun. The new UK Light Gun 1000-yard five-shot record now stands at 2.462 inches. For those who like load details, Emily uses Lapua brass, Vihtavuori N150 powder, CCI 450 primers, and Berger 105 grain VLD bullets loaded with Wilson hand dies.

The World Benchrest Shooting Championship (WBC) was held in New Zealand earlier this month. The 14th WBC was conducted November 7-11, 2017 at the Packers Creek Range, Nelson, New Zealand. The match was hosted by the Nelson Branch of the New Zealand Deerstalkers Association on behalf of the World Benchrest Shooting Federation (WBSF). There were 76 competitors from 14 nations. Many competitors said this was one of the prettiest ranges they had ever seen. The Kiwi hosts put on a great event in a beautiful South Island shooting venue.

There were both individual and team awards. The Australian Benchrest Team 1 took top honors in the Two-Gun Team Match. Congrats to the Aussies, who had a great team effort to post a winning 0.283212 Agg. Finishing Second in the Two-Gun Overall was Team US1 with 0.286112. The 4-Man US1 Squad also won the Heavy Varmint Team Competition with a 0.270162 Agg, while the US2 foursome won the Light Varmint Team title with a 0.290925 Agg.

Standing atop the podium (center) are the four members of Team Australia 1, winners of the 2017 WBSF Team Championship:

Championship Organizer Graeme Smith said that the Championship got away to a cracking start with Kiwi shooter Greg Couper winning the Light Varmint Small Group contest with a Group of .076, just over the current world record. Overall the day was won by American Wayne Campbell, who was in hot form having recently won the USA Nationals. Day 2 provided the only new World Record shot at the Championship with Australia’s Steve Sori shooting a new Small Group record at 200 yards of 0.138, well under the existing WBSF record of .160. Mike Conry of the USA led the field for the day. The next two days followed the previous pattern with Wayne Campbell taking the Heavy Varmint 100-yard contest and Mike Conry the 200-yard event. The most sought-after medals were for the Two-Gun Aggregate, covering four days of competition. Mike Conry dominated the field, winning the Gold Medal, followed by Wayne Campbell taking Silver, and David Kerr of Australia earning Bronze.

In short-range benchrest, final standings can turn on a few thousands of an inch, so groups must be measured with great precision.

The “top gun” at the match was American Mike Conry from Texas. Mike won the Heavy Varmint Grand Agg as well as the Two Gun Overall Aggregate. Mike received glory, medals, and most importantly, a new AMP Annealing machine from the New Zealand-based manufacturer, AMP Annealing. AMP’s President, Alex Findlay told us: “Mike Conry was definitely the dominant shooter. By the end of the awards he was just about weighed down with all the medals around his neck.”

There were some ultra-small groups shot at the match. Shown below is an amazing 200-yard 5-shot Light Varmint Group shot by Australian Steve Sori. This tiny 0.138 group is a pending new World Benchrest Shooting Federation Record. Steve’s LV rig featured a BAT action, 1:13.5″-twist Krieger barrel, Scoville stock, and March High Master 48X scope. The cartridge was the 6PPC (of course), with Bart’s 68gr Bullets pushed by N133 and Federal 205m primers in Lapua Brass. Bullet-maker Bart Sauter is a Forum Member — its’ great to see his bullets perform so well at the WBC.

While this was an internationally-sanctioned match, the yardages shot were 100 yards and 200 yards. This was NOT a Metric Match with targets at 100m and 200m.

The Science of Annealing — Facts Uncovered, Myths Busted

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

The science behind annealing during the manufacture of new cases is well-established. What happens after that, when we repeatedly reload and anneal those same cases, has always been somewhat of a “dark art”. To help separate scientific fact from fiction, the creators of the Annealing Made Perfect (AMP) Annealer machine have conducted detailed studies of cartridge brass. The AMP Team’s studies offer some remarkable insights, while disproving a number of myths about annealing. Will annealing tighten your groups? The evidence of these studies shows it could.

The test results are fascinating. The team compared brands of brass, sectioning brass to examine both alloy composition and thickness from case mouth to case-head (bottom). They also examined how carbon build-up affects next tension. And they determined how brass changes over multiple loading cycles. They even did a series of bullet-pull tests to analyze factors affecting neck tension. Here are some of the key subjects in the reports:

Brand by Brand Analysis — How the cartridge brass alloy varies among different manufacturers.
Bullet Release and Neck Tension — Tensile Bullet-Pull tests show factors affecting neck tension.
Neck Tension and Carbon — How carbon build-up inside the neck affects “neck tension”.
SS Tumbling and Hardness – How tumbling with stainless media affects brass hardness.
Case Cleaning (Ultrasound and Tumbling) — How case cleaning affects annealing.
Multiple Loadings — How brass performs when annealed every reload over 10+ cycles.

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

You really should read the reports — there are some fascinating revelations. The AMP team made longitudinal sections of various cases to show different case wall thicknesses and head geometry. These examples also show how the hardness of the case varies from the case mouth to the case-head. Both virgin and used, annealed cases were examined.

Bullet-Pull Tests — Using advanced tensile test equipment, AMP experimented with different combinations of dies, reloading sequences, and neck hardness to ascertain the best practice.
Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Carbon Inside Your Case-Necks May Be a GOOD Thing
AMP’s testers found carbon in necks can be beneficial: “Even with identical interference fit and neck hardness, as the carbon layer increased (microscopically), the force to draw the bullet decreased. It would appear the carbon acted as a lubricant. Interestingly, the [pull force] standard deviation also improved, i.e. the case to case variation in the force required to draw the bullets decreased.”*

Read the Full Test Reports

The AMP team’s objectives were to clarify some misconceptions on just what annealing does and does not do, and also to establish the best practices for consistent results. They have consulted with three independent certified metallurgy laboratories to produce some definitive information. So far, the Stage 1 and Stage 2 reports have been released. The studies include a report on the general physical properties of cartridge brass, including grain structures, hardness scales, time/temperature annealing information, and what can cause de-zincification.

The FULL REPORTS, including comprehensive appendices, are found here:

Stage One: https://www.ampannealing.com/articles/40/annealing-under-the-microscope/

Stage Two: https://www.ampannealing.com/articles/42/annealing-under-the-microscope/

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Examining Different Brands of Brass — What the Tests Revealed

Is Lapua brass harder than Norma? Is Lake City better than Remington? You’ll find answers to these and other questions in AMP’s annealing studies. One of the key findings in Stage 2 of Amp’s research is that brass from different manufacturers does vary in the distribution of material in the walls of the case.

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Stage Two Conclusions:

— Different brands of the same cartridge cases can require different annealing power settings due to differing case wall thickness in the neck and shoulder region. The greater the mass of brass to be annealed, the greater the power requirement. Lot to lot variation within the same brand can occur for the same reason.

— The bushing die used in this set of tensile bullet pull tests gave significantly more consistent results than the standard neck die with expander ball.

— Cases should be annealed every reload in order to get the best repeatability.

Case Variations: Brand to Brand, and Lot to Lot

Here is a sample from AMP’s test report:

Analyzing Different Brands of Brass
In our Stage One report, we demonstrated that there is insufficient variation in alloy composition between brands to account for the variations we experience when annealing different brands of the same cartridge case. We therefore sought to confirm that it is the mass of brass to be annealed which accounts for the difference. Below are sectioned samples of four different brands of .223 Remington cases.

Both the Lapua and Norma neck walls are 314* microns (0.01236”) at the mouth. The Lapua neck wall thickens to 348 microns at the junction of the neck and shoulder, and the Norma neck thickens to 325 microns. Through the shoulder, however, the walls of both cases thicken to 370 – 380 microns. Once past the shoulder, they both taper back to 314 microns, before starting to thicken again, moving towards the case head.

The Lapua case requires AMP Program 47 to anneal correctly. It is the heaviest of the four cases tested through the shoulder region. The Norma case, which is only slightly lighter through the same region, needs Program 43.

The Remington case is very similar to the Lapua and Norma cases in the neck region, but it actually thins fractionally through the shoulder and front section of the body. The AMP program setting for Remington 223R is P32.

The Lake City case is the thinnest throughout of all four samples. It only requires Program 28.

The above samples clearly demonstrate that the mass of brass to be annealed is critical to the power requirement for correct annealing.

To see how the AMP Induction Annealing Machine works, watch this video:

* However, in Stage Two of AMP testing, the testers experimented with clean, carbon-free necks with dry lube. There was some indication of greater tensile pull consistency with dry-lube, but AMP plans to do more testing.

Barnard Action Q & A with John Whidden

Q: In addition to the Model P, What Other Actions Does Barnard Produce?

Whidden: Many shooters familiar with the Barnard Model P, but we now carry six (6) other Barnard actions. These include the PC action with multiple bolt/port options, the Model SM repeater (with Rem 700 footprint), and the PLM which is a perfect fit for the big .338 Lapua Magnum cartridge.

Q: What Are the Key Features of Barnard Actions?

Whidden: Barnard actions have won a reputation for accuracy, robustness, and exceptional straightness and quality in manufacture. Their design is very rigid and stiff. The three-lug bolt gives a short bolt-lift. These qualities are available in the full line of of Barnard actions. The fact that many models include the excellent Barnard trigger make them a good value among custom actions.

Q: What Barnard Actions Do You Recommend for Particular Disciplines?

Whidden: For those interested in F-Class and Long Range Benchrest shooting styles the Model PC is very attractive. The PC is the same size and footprint as the familiar Model P except that the PC offers different bolt/port configurations. Available in the PC are right bolt/left port, left bolt/right port, and dual ports. The Model S and SM actions will accept Remington pattern triggers and fit into stocks inletted for the Rem 700. This gives PRS shooters the chance to have a superb action with a three-lug configuration for their use. The PL and PLM are sized for the .338 Lapua Magnum cartridge and wildcats based on that case-head size.

You can check out the 6.5 Guys’ website at www.65Guys.com. Below is a sample from one of the 6.5 Guys’ best articles — Five Tips on getting started in practical/tactical matches.

We often meet people who are new to long range precision shooting, and want to improve their knowledge and skill level. However, they aren’t sure if they are ready to sign up to compete in a match. They often ask, “What knowledge or skills [and gear] are necessary to compete in a match?”

TIP ONE: Make Plans and Commit to Go

First you need to start by finding a match to attend. We recommend starting with any match that may be within a reasonable driving distance. This may likely be a local “club” match, many of which are held on a regular basis. Once you decide on the match you want to attend, do your homework. This means finding out if you need to pre-register or pre-pay the match fee. Commit to going by registering for the match and putting it on your schedule.

3D Metal Printed Rimfire Receiver from New Zealand

Rimfire .22 LR Receiver action 3D Printer Printing custom action New Zealand 40X PT&G

Here’s something truly innovative — a 3D-printed metal rimfire receiver!

Forum member Marcos G. (aka MFP_BOP) has designed and created his own rimfire action. But it’s not machined or forged. This new action was created with a 3D sintered metal printer. A 3D modeler by profession, Marcos has the requisite skill set and access to a very high-tech (and expensive) metal printer. As printed, the actual receiver is shown below. It has just been sent out to be age-hardened to 40 HRC, after which final finish work (e.g. cleaning up tenon threads) will be done. To learn more about this 3D-printing project, read this FORUM Thread.

Rimfire .22 LR Receiver action 3D Printer Printing custom action New Zealand 40X PT&G

When most of us think of 3D printing, we think of small plastic parts — nothing as strong as steel. But there are 3D printers that employ sintered metal to build complex metal components. Marcus says the receiver he’s created should have “stated yield and tensile strength similar to investment casting.” The material used for the action is 15-5 PH® Stainless Steel (in sintered form).

The action was designed to use a PT&G 40X rimfire bolt. Marcos notes that “There is an extraction cam inside of the action, something that would be very hard or impossible to do by regular machining and/or EDM.”

Born in Brazil, Marcos now lives in New Zealand. He tell us that: “New Zealand is a very gun-friendly country. I just need my A-CAT license to make [a receiver.]” So there are no special legal restrictions (as might apply in the USA). The printer is EOS270 laser metal sintering machine. Marcos says: “The current price for one of those machines is in five figures, but I am 99.99% sure that in 5-7 years this technology will be readily available to anyone.”

As designed, the receiver was 1.4″ in diameter. Marcos reports it came out of the printer at 1.403″. The designed boltway is .690″ and it came out .687″. Marcos notes: “I haven’t noticed any warping. The threads are rough, really! Interior and exterior finishes are really good though, probably because of the way it’s been printed: upside down (must have gone through tumbling afterwards). I will have to run some taps and single-point-cut the tenon threads to clean them up.”

Rimfire .22 LR Receiver action 3D Printer Printing custom action New Zealand 40X PT&G

Marcos says the actual printing process took a lot of time: “I should have asked how long it took to be printed!” But consider this, the 7″-long receiver is created in layers only 20 microns thick, so you can understand why the process took so long.

Reasons to Print a Rimfire Receiver
Marcos 3D-printed his own action basically to save money: “Some may be asking why I printed this receiver. Here’s a little history… I tried different ways to bring a Stiller 2500X action into New Zealand. The final price to my door was NZ $3000.00 (about $2195.00 USD). Designing and making one would be way cheaper, but I felt nobody here could machine the internal abutments with precision. Also printing was still a little cheaper and printing offered the chance to put in it all details I wanted — such as M4 threads, internal cam, and fillets.”

The short explanation of why we anneal brass is to return the brass to a softer and consistent hardness after the brass has work-hardened from repetitive firing and sizing. As the President/co-owner of Sinclair International for over 21 years I saw a lot of products come through our doors that annealed brass but these products always seemed like they had very little supportive data and research behind them. Most of them were based on some type of torch system. The New Zealand-based father/son team of Alex and Matt spent these past three years addressing the challenging questions about annealing:

- What is the correct temperature to reach when annealing?
– How long should you take to get to that temp and how long should you remain there?
– How frequently should you anneal?
– Can you ruin your expensive brass?
– How do we make the process repeatable for the handloader?
– How do you accurately measure the case hardness?

They worked closely with the Electrical Engineering Department at the local University of Technology and invested a lot of capital into detailed metallurgical research. Their decision to use induction heating was because of its repeatability and the ability to reach exacting and consistent temperatures. Induction annealing is achieved by placing the cartridge in a magnetic field thereby inducing eddy currents within the brass and heating the brass without contacting the brass physically. To learn more, I suggest you visit the AmpAnnealing.com website. It is very informative.

Why should you anneal? If you are just a casual reloader, than annealing isn’t necessary but if you a serious wildcatter or competitive shooter you may want to consider it. More and more competitive shooters anneal their cases (not necessarily for adding life to the cases) to achieve more consistent pressures and velocities.

My first favorable impression was received by just opening the extremely well-packed shipping box. You could tell these guys take a great deal of pride in their product. The unit comes with three cartridge-specific pilots (you decide on which pilots), a shellholder collet, a power cord, a thorough, well-written, easy to follow instruction manual, and a USB cord for future software updates.

This machine is so easy to use that I was up and running within a few minutes. All I had to supply was the shells, the correct shell-holder and an aluminum pan to drop the hot cases into. I started annealing some unturned .308 Winchester cases (Lapua headstamp) that had four firings. First I screwed the pilot for .308 cases (#11) into the machine, placed my .308 shellholder into the supplied shellholder/collet and turned the power on. The display fired up right away and soon registered the program level that the machine was set to.

Since the machine uses induction heating, you need to set the heating level for the correct setting for the brass you are using. The alloy being used isn’t as important as the thickness or amount of brass in the neck and shoulder region. For example, Lapua and Norma have more brass in that area so the setting would be higher for these brands than Winchester brass. Also, if you have neck-turned brass, the setting would be reduced from the standard setting because there would be less mass in the air gap.

This manufacturer-produced video shows how the AMP annealing machine operates:

The settings are obtained by referring to the “Settings” section on the AMP website and are broken out by cartridge, brand, standard unturned cases, and then neck-turned cases with various amounts of wall thickness removed. A great service that AMP provides to the handloader is that you can send sample cases of your brass to them (U.S. location in Wolcott, Indiana) and they will test the hardness for you and send you the exact setting for your specific lot of brass.

My setting for unturned Lapua .308 Winchester brass was “92”. The buttons on the front of the machine allow you to adjust the setting quickly. After you set the program number, the setting is locked in after the first use until you change it again. I placed the first case in the shellholder, lowered the assembly down through the pilot and into position. I then hit the start button which illuminated immediately and then about 6 to 7 seconds later, the light went off signaling that heating was completed.

Now, be aware, these cases are extremely hot. I lifted the case out using the shellholder/collet and then dropped it into my aluminum pan. I then placed another case into the holder, put it into the machine and then repeated the process. Once I got the coordination down, I did 100 .308 Win cases in about 24 minutes. I did some 6mmBR cases later (Lapua) and annealed 100 cases in about 15 minutes at the “75” setting. I found myself raising my shop stool a little higher than normal so I was at a comfortable height in relationship to the top of the machine. Very easy to do — I actually had a student do a few cases with me and she had no problem at all following the instructions.

There is a thermal cut-off that prevents the machine from overheating. Depending on the setting, this can occur after 20 to 35 minutes of continuous use. When this has occurred, simply leave the machine on and the fans will cool it down so you can resume annealing. This isn’t surprising considering the amount of heat being generated.

All in all, I found this machine extremely easy to setup and operate. Now, does it work? I have test batches of brass that I am going to run over the chronograph in 10-round strings. I plan on running at least 10 strings of annealed brass and 10 strings of unannealed brass out of the same lot, same number of reloadings/firings and out of the same gun. I plan on alternating annealed strings and unannealed strings with a cooling off period every 20 rounds. When I do testing, I have my wife pre-label my batches as Batch A and B so I won’t know what rounds I am shooting until I get back from the range. I’ll make the results available as soon as I can. My expectation is that velocities will be more consistent based on my understanding of the lab results that the Findlays have achieved with their Annealing Made Perfect machine.

Advanced Barrel Block F-Class Stock from New Zealand

True-flite trueflite barnard action new zealand barrel block F-Class F-Open

Here’s an interesting new F-Class Barrel Block Stock from True-Flite NZ Ltd. in Gisborne, New Zealand. This innovative design features a fore-arm barrel block that clamps around the barrel, allowing the action to free-float. We like the way a wood lower section (with pistol grip) is mated to the metal “spine” of the chassis. That creates a nice look and feel.

The folks at True-Flite state: “This stock has been designed by Steve Mann, and was developed in house here at True-Flite. Utilizing a 150mm barrel block, which clamps the barrel into the stock (allowing the action to free float), enables us to fit large, full-profile barrels, and still keep under the 10 kg weight restriction when running a Nightforce scope. This stock tracks like a demon, making it a very competitive rig.”

While this chassis is designed for the New Zealand-made Barnard actions, it can also work with other round actions. Target Shooter Magazine notes: “The great thing is, because the action is unstressed, you can get away with using … a Remington — rather than forking out for a custom action.”

Barnard Model P Action from New Zealand
Here’s a Barnard Model P action, which was originally developed in 1982. These three-lug actions are very smooth. They are popular with Palma rifle shooters and F-Class shooters. Designed for the Palma or long-range shooter, the Model P Single shot action is available in right-hand or true left-hand configuration (with other bolt/port configurations in the Model PC).

The bolt carries three forward locking lugs, is equipped with a Sako-style extractor and can be supplied to accept any case rim up to 0.534″(standard magnum rim). The Bolt undergoes finish machining after hardening, and is hand-lapped to its mating receiver. The receiver is 4340 chrome/moly/nickel steel, through-hardened to 38 RC and finish-machined after surface hardening to ensure concentricity.

Tikka T3 — Video Reviews from New Zealand and Scotland

Tikka T3 Review new zealand hunting scotland varmint rifle

The Tikka T3 rifle is very popular with hunters around the globe — for good reason. These rifles offer smooth-running actions, easy sub-MOA accuracy with good ammo, crisp triggers, and ultra-reliable detachable box magazines. The Tupperware stocks aren’t super-rigid, but they are comfortable and easy to handle. If you are looking for a hunting rifle, the Tikka T3 is a smart choice, offering good performance for the price (which starts at less than $580.00 for the T3 Lite version). The T3 series is offered in a wide selection of chamberings, from .204 Ruger up to the large magnums.

Here are two good Tikka T3 video reviews, the first from New Zealand, the second from Scotland. Both reviewers are experienced hunters who explain why the T3 is well-suited for hunting applications. In the first video, Mitch of BushBrothersNZ reviews a T3 with polymer stock and stainless barrel chambered for the .270 Win. Mitch focuses on the T3’s controls and functions, with particular attention to the operation of trigger, safety, and bolt.
