If you have ANY interest in custom rifle actions, you MUST watch this video from UltimateReloader.com. Folks, definitely watch the video — it is VERY informative! To produce this video, Ultimate Reloader’s Gavin Gear visited the BAT Machine facility in Post Falls, Idaho, and interviewed BAT owner Bruce Thom.
In the video Bruce Thom demonstrates how BAT Machine actions are created from start to finish. Bruce shows every stage of the process, employing multiple high-tech machines. It’s impressive — Forum members say that this is a “must-watch” video. Gunsmith Jackie Schmidt noted: “Great Video. Even though I have been in the machine shop business for 50 years, I still marvel at the new innovations in precision machining. Bruce has a very down-to-earth, common sense approach to explaining what to many seems like machining wizardry.” And Mark T. posted: “Watched it last night. Excellent video and excellent machining practices — precision from beginning to end.”

For further explanation of the action production processes, with step-by-step listing of how receivers and bolt assemblies are created, read Gavin Gear’s full BAT Machine Article on UltimateReloader.com.
BAT Machine Company Was Started 29 Years Ago
Back in 1991, Bruce Thom started BAT Machine Company, which was incorporated later in 1996. Bruce’s shop stared with manual machines, quickly moving to CNC machines later in the 1990s. BAT Machine quickly achieved a following among benchrest shooters for crafting superb actions that exhibited flawless function and superb machining. Those qualities, benchrest competitors realized, helped produce tiny groups, win matches, and set benchrest records. BAT Machine now makes rifle actions for a wide variety of disciplines: F-Class, PRS, ELR, hunting, and of course short- and long-range benchrest.
BAT Action Body Machining Stages
As shown in the video, here are the major stages for the fabrication of a BAT Machine receiver body:
1. Start: raw 17-4 stainless round bar (higher toughness than typical barrel/receiver steel)
2. Heat treat
3. Bore central hole (for EDM wire), face ends
4. EDM machining (cut bore and raceways)
5. True OD, cut receiver threads and lug seats
6. Cut tang and related features
7. Finish machining including body OD, integral lug (if equipped)
Final Production Stages — Polishing and Deburring
After the receiver body and bolt are machined, they go through a deburring and polishing process.
In the image above you can see the stages. At left is a receiver body straight from machining. Some hand work is typically performed to break interior edges that are sharp from machining. In the center, the receiver shows can see the initial polish stage. During this stage, machining marks are removed by coarse polishing. Additionally for receivers that will be nitrided, that will be done next. But for actions that are NOT nitrided, a final polish brings the parts up to a high luster, as show on the right.
After polish (and nitriding if that applies) the bolts and receivers get a finish assembly, and testing for proper smooth functioning. The receivers are then registered with the ATF and shipped to the customer.

Our friend Gavin Gear of UltimateReloader.com often gets to test the latest and greatest reloading tools before they hit the market. He does a good job showing the features of new products with informative videos. Today we present three interesting products that Gavin has reviewed. First off is the impressive new RCBS Rebel reloading press. Next is the versatile three-head Case Prep Trio machine from Hornady. Third, Gavin reviews new Die Lock Rings and Breech Lock Die Bushings from Lee Precision.
RCBS Rebel Single-Stage Reloading Press
Most hand-loaders have used an RCBS Rock Chucker press at one time or another. Recently RCBS unveiled its new Rebel single-stage press. Like the Rock Chucker, the Rebel has a Cast Iron frame, but with a bigger base and taller arch (for a larger opening). The most important change is that this new Rebel press ejects primers out the bottom of the ram. This a big deal — just put a bin under the press to collect spent primers. However — take note — the Rebel has no on-press priming. You need to prime your cases separately. That’s not really a major issue, as we know the majority of our readers prime separately using hand or bench priming tools.
In this video Gavin loads ammo on the new the Rebel single-stage press and explains its notable features, including the primer ejection through the ram.
Note, RCBS is currently running a Buy Green Get Green Rebate Program. The Rebel Press qualifies for a $50.00 Rebate. And right now, MidwayUSA has the Rebel Press on sale for $186.99. So your net cost, after RCBS Rebate, is just $136.99. That’s a great deal on an excellent press.
Hornady Lock-N-Load Case Prep Trio
Hornady’s compact Case Prep Trio machine (item 050160) packs a lot of functionality in a small package. This triple-threat tool has a small footprint, yet it can perform three tasks as well as much more expensive, tower-style case prep units.
Gavin Gear does a nice job explaining the features of the Case Prep trio. Watch this video to see how it can help you perform chamfering, deburring, and pimer pocket uniforming tasks more efficiently.
With three active stations, you can chamfer, deburr and clean primer pockets without having to change tools. The Case Prep Trio ships with inside chamfer, outside chamfer, and deburr tools. You can also use the machine with other optional 8/32 threaded accessories such as primer pocket reamers and case neck brushes. We’ve used this machine and it works well. The only negative is that you will get metal shavings on your bench (unlike some of the larger case prep centers). We’ve seen some guys put a small pan under the power head — then you can just dump the shavings out of the pan.
New Lee Die Lock Rings and Spline Drive Breech Lock Bushings
New basic lock ring in left hand. Older non-splined ring in right hand.
In this recent video Gavin Gear reviews three types of die accessories from LEE. These work for virtually all standard dies, not just LEE-brand reloading dies. The new LEE basic silver-finish die lock rings now feature splines for enhanced grip and compatibility with LEE’s new die lock ring wrench (photo right). They still boast a rubber 0-Ring that helps “float” the die for improved cartridge concentricity.
LEE’s new Ultimate Die Lock Rings have two major improvements — a colorful anodized finish, and a split-ring design with a tensioning screw, that allows these rings to be clamped securely to your dies. Available as a set, this package includes three ultimate die lock rings, and a plastic die lock ring wrench.
Gavin also reviews Lee’s new Spline Drive Breech Lock Bushings for use with presses fitted with LEE’s Breech Lock system. These new Breech Lock bushings allow rapid change-out of dies without modifying the setting. The colorful new bushings feature splines on top that work with the new Lee Lock ring wrench shown above. In addition, the Breech Lock Bushings have a clamp to preserve die depth setting.

Our friend Gavin Gear has just released an excellent video showing how to make a threaded Modified Case for use with the Hornady Lock-N-Load Overall Length Gauge. You can watch Gavin make a Modified Case start to finish in the video below:
Video Shows How to Drill and Tap Modified Case
Gavin has some clever tricks. First he uses a sizing die to hold the cartridge case during the threading process. Second he uses two drill bits in sequence — a smaller bit to ream out the primer pocket, and then a larger “M” bit to increase the hole diameter before threading the brass. Finally he leaves the threading tap IN the brass, locks the tailstock, and then “gently pulls on the quill” to remove the brass from the die held in his lathe (See 5:46 timemark).
Get the Correct 5/16″-36 RH Tap
Unfortunately, Hornady has selected an uncommon thread type for OAL Gauges. You probably won’t be able to buy the correct 5/16″ – 36 RH HSS Tap at your local hardware store. However you CAN order this special tap from Amazon for $9.99.
Modified Case Q & A — TECH TIPS
Why do I need a Modified Case?
Every serious reloader should have a Modified Case for each cartridge type they shoot. The reason is that this allows you to get very precise measurements of the length-to-lands in your chamber. When used with the Hornady OAL Gauge, with some practice, you should be able to get repeatable length-to-lands measurements within about 0.015″. We generally do 4-5 measurements with the OAL Gauge and usually 3 or 4 will be “on the money”. NOTE: We recommend a gentle, easy pressure on the plastic pusher rod. Don’t push too hard or you will jam the bullet hard into the lands, which produces inconsistent results.
Can’t I Just Buy a Modified Case?
Hornady makes a variety of Modified Cases sold on Amazon and through retailers such as Midsouth. While Hornady makes 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 with a custom Modified Case.
If you do decide to make your own modified case, you’ll want to start with a case that’s been fired in your rifle. That way you get the best fit to YOUR chamber. Also, you won’t need to expand the neck to provide bullet clearance. Then you need to drill out the primer pocket and tap the base of the case to match the threads on the Hornady OAL Gauge tool. Make at least two modified cases, as you’ll probably misplace one at some point.
Erik Cortina Makes a Modified Case
If you want to learn more about making Modified Cases, top F-Class shooter Erik Cortina has also created a helpful video showing the process he uses to make modified cases. In Erik’s video, he shows how he taps a case to work with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). Erik also explains how to get the best results when using the Modified Case to measure length to lands.
MORE INFORMATION: Want to learn more? We published a much longer story in which Erik explains in greater detail how to made the Modified Case. That article illustrates the 5/16″ – 36 RH HSS Tap required and shows how to set up the lathe to drill and tap your case.

The Bergara B14-R is a high-quality, accurate .22 LR rimfire bolt-action rifle. The rifle’s accuracy and functionality make it a good choice for NRL22 competition. And with stock geometry and ergonomics that duplicate a full-size centerfire rifle, the Bergara B14-R is also an excellent choice for cross-training. By training with a rimfire rifle, you can get essential “trigger time” while saving money. Good centerfire ammo can cost $1.50 per round or more. Decent rimfire ammo can be found for $6.00 per 50rd box. That’s just 12 cents per round.
Click above photo to load full-screen high-rez image.
To find out how well the Bergara B14-R can perform, Gavin Gear of UltimateReloader.com recently tested a B14-R (carbon-covered barrel version) at his private range. Using a variety of Lapua and SK Ammo, this rig delivered impressive results. Watch this video to see the B14-R in action.
“The B14-R is a great shooter, and for me it felt very familiar. Just like shooting one of my centerfire match guns, but without all of the recoil!” — Gavin Gear
Gavin reports: “At the 2020 SHOT Show, Bergara announced the B14-R trainer. The concept? Take the B14 HMR series centerfire rifle formula, and adapt it for rimfire. The result is a .22 LR rifle you can shoot all day long without wearing out your arm or your wallet! It looks/feels like a centerfire long-range precision rifle. And that’s what makes this rifle a GREAT training platform for serious long-range shooters.”
The B14-R comes with a 18″-long 1:16″-twist threaded barrel. The single-stack .22 LR magazine is the same size as a short action AICS mag. The Bergara B14-R shares Rem 700 specs, so it is compatible with Rem 700 stocks and aftermarket triggers. Weight with standard barrel is 9.2 pounds without optics, or 8.1 pounds for the carbon version seen here. MSRP for basic version is $1150.00 and street price is $950.00.
Gavin told us: “I couldn’t wait to get the B14-R out to my new 50-yard ridgeline range to see how it would perform with premium .22 LR ammunition. Once I shot this rifle suppressed, I didn’t want to take off the can. The 18″ barrel really works well with the SilcencerCo suppressor to help keep the overall length reasonable, and balance is spot-on.” NOTE: This rifle has the optional carbon-covered barrel.
As tested, the rifle was equipped with these components:
Athlon Midas TAC 6-14x50mm FFP Scope with MK Machine lever, Lone Star bubble level SilencerCo Omega 300 Suppressor with 1/2×28 direct thread mount Harris S-BRM 6″-9″ Bipod with aftermarket swivel tension lever
Outstanding Accuracy with Lapua and SK .22 LR Ammo
Remarkable accuracy for a factory rifle earned this Bergara its Sunday GunDay selection. Shooting with bipod and rear sandbag, Gavin was able to achieve multiple, sub-half-inch groups at 50 yards. The best group shot with SK Match ammo was a remarkable 0.22″ as measured by Ballistic-X software (see below). That’s an impressive 0.42 MOA at 50 yards. If you watch the video above, starting at 14:40 time-mark, you can watch Gavin shoot that 0.22″ group.
Here are two more groups, both under 0.5″ at 50 yards. Lapua Center-X on left, SK Match on right. Gavin says that “with good conditions, 0.35″ 5-shot groups at 50 yards are easily attainable.”
B14-R Trigger Tested with TriggerScan TS-11
Gavin tested the Bergara’s trigger with the TriggerScan TS-11 from DVORAK Instruments, a very sophisticated, high-tech device. Gavin states: “This trigger works well, and mine was adjustable down to just over 2-lb peak force for pull weight. I ran a 3-scan pass on the B14-R trigger with the pull weight set to minimum [barely over 2 pounds].”
Gavin notes: “You can see how consistent this trigger is by how well the scan graph plots overlap! This trigger is great for an out-of-the-box rifle like this, and it’s great to know that I can always swap out triggers and use the same exact Remington 700-compatible trigger that I’m running in my match guns.”
Gavin Gear’s Closing Thoughts — More to Come
The Bergara B14-R rimfire trainer has been a great rifle to shoot and has exceeded my expectations. The B14-R feels like a full-size PRS rifle, has the same basic features, but is chambered in .22 LR. I have been amazed by the accuracy I’ve achieved with this rifle with Lapua and SK match ammunition — it’s very confidence inspiring.
This rifle feels right and shoots great. I can’t wait to get more steel targets setup, and to go deeper into calculating dope for the ammunition I will shoot with this rifle. Perhaps I’ll think about competing in an NRL22 match at some point. If you are looking for a rimfire trainer, look at the Bergara B14-R for sure. It checks all of my boxes for this type of rifle!

COVID-19 stay-at-home orders have created abundant free time at home for millions of Americans. To fill otherwise empty hours, we know many readers have been reloading ammo — LOTS of ammo. And quite a few of you folks are thinking of getting a progressive press to increase output. Because multiple operations take place with a single pull of a lever, a progressive press can produce way more ammo in a given period of time than any single stage press. With a progressive, on the ram up-stroke, the multiple stations can simultaneously remove spent primer, full-length size case, drop powder, seat bullet, and crimp (if desired). Most progressives are also set up to prime cases with the ram in the lower position — though some guys prefer to prime manually.
Progressive presses aren’t just for high-output pistol ammo or bulk rifle ammunition. Good progressives can be adapted to do certain reloading tasks for top-on-the line match ammo. You might use a progressive for decapping, priming, and sizing, then throw powder and/or seat bullets separately. Some Champion shooters do use progressives to load their match ammo! For example 5-Time National Long Range Champion John Whidden and 2020 Berger SWN F-Open Champion Jay Christopherson both use progessive presses for some (but not all) operations.
To help you get started with progressive presses, here are five videos from UltimateReloader.com that cover six popular machines, from the elite Mark 7 Evolution to the inexpensive Lee Pro 1000. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency.

Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.

As folks are stuck at home with the Pandemic lock-downs, many guys are thinking about projects involving their AR-15s sitting in their safes. We’ve seen some threads in our Forum asking about the .224 Valkyrie, an AR-centric cartridge that offers significantly better long-range performance than the .223 Remington (5.56×45). If you own a .224 Valkyrie, or are thinking about adding a .224 Valkyrie upper to your MSR (Modern Sporting Rifle) arsensal, here is load information from industry leaders Hodgdon and Sierra.
With the 90gr SMK (or similar High-BC projectiles), the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil.
Hodgdon has reloading data for the .224 Valkyrie, a popular new cartridge optimized for the AR15 platform. “At Hodgdon, we’ve been researching this cartridge since before its introduction and are excited to release load data for the Valkyrie featuring powders like Hodgdon CFE 223, IMR 8208 XBR, and Hodgdon Varget” reports Ron Reiber, Hodgdon product manager/ballistician. Access the .224 Valkyrie Data via Hodgdon’s Reloading Data Center.
While new load data will continue to be updated, there is currently data for 80 different loads with bullet weights ranging from 50 to 90 grains. NOTE: The load data covers Hodgdon, IMR, and Winchester brand powders only. See Sierra Data for other powder brands. Bullet brands included are: Federal, Hornady, Nosler, Sierra and Swift.
About the .224 Valkyrie Cartridge
Basically a 6.8 SPC necked down to .22, the Valkyrie has a shorter case than the .223 Remington (and 5.56×45 NATO). This allows you to load the longest, heaviest .224-caliber bullets and still feed reliably from an AR15-type magazine. Designed to rival the .22 Nosler while still running well in ARs, the .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil.
The new .224 Valkyrie has already developed a loyal following: “Shooting heavier bullets in an AR-platform rifle that maintain supersonic speeds beyond 1,300 yards has captured the interest of shooters and handloaders everywhere” — Hodgdon Powders
Our friend Gavin Gear of Ultimate Reloader.com found a superbly accurate load with Berger 80.5gr bullets.
IMPORTANT: Check Out Sierra’s .224 Valkyrie DATA
Sierra Bullets has also published extensive load data for the .224 Valkyrie. This covers over a dozen powder types — many more than the Hodgdon database. Sierra’s .224 Valkyrie load data covers projectiles from 50 grain all the way up to 95 grains. With the 90 to 95 grain bullets, the little Valkyrie can give 6mm match cartridges a real run for their money — offering similar ballistics with less recoil. When selecting a barrel for the long .224-cal bullets, specify a fast enough twist rate: “Sierra recommends a 1:6.5″-twist barrel for the #9290 22 cal 90 gr HPBT bullet. However, for cartridges like the Valkyrie, that can push them over 2650 fps muzzle velocity, a 1:7″-twist barrel will stabilize the bullet correctly.”
Gavin Gear tests .308 Win ammo with his DPMS LR-308B, AR10-type rifle.
Our friend Gavin Gear of UltimateReloader.com owns a DPMS LR-308B, an AR10-type semi-auto rifle. Gavin finds that his DPMS has a healthy appetite for ammunition. So, he set up his Hornady Lock-N-Load progressive press to produce .308 Win ammo. This video shows the process of press set-up and operation, complete with Hornady’s automated Case Feeder and Bullet Feeder. Employing elevated rotary hoppers, the case feed and bullet feed systems really speed up production. The automated feeders allow the operator to produce cartridges without ever touching case or bullet with his hands.
If you need large quantities of .308 Win ammo for 3-Gun matches or tactical games, and if you value your time, a progressive press may be a wise investment. The progressive can load a complete round with every cycle of the press handle. With Case Feeder and Bullet Feeder in place, the Hornady L-N-L can easily crank out a new .308 round every 3-4 seconds (watch video at 5:25). Conservatively speaking, that’s 15 rounds per minute sustained production (and some guys can go even faster).

Probably the most popular centerfire rifle round in the Western Hemisphere is the .223 Remington and its metric match, the 5.56x45mm. Though many folks use “.223 Rem” and “5.56×45″ interchangeably, there are some meaningful differences in specifications for the original .223 Rem and the 5.56x45mm cartridge, as adopted by the U.S. military and NATO armies. The default chamber throats are slightly different and the .223 Rem is rated at 55,000 PSI vs. 62,366 PSI for the 5.56x45mm.*
.223 Rem vs 5.56x45mm — Key Differences
There is a truly outstanding, very thorough article on the subject, published by LuckyGunner.com.** This involved extensive testing, with pressure monitors, of 5.56x45mm ammo in .223 Rem chambers. Those tests revealed the peak pressures. Here is one of the ammo test charts:
NOTE: “The observed chamber pressure for Federal XM855 5.56mm ammunition in a .223 Rem chamber exceeded .223 maximum pressures, but not by a massive amount. The ninth shot (the red line) was an underpowered cartridge which exhibited significantly lower velocity and pressure than the other rounds, so it was excluded from the average velocity and pressure numbers for this chamber.”
And if you’re curious, LuckyGunner also fired .223 Rem ammo in a 5.56x45mm NATO-chambered AR15 rifle. As you would expect, the peak pressures were significantly lower, but the .223 Rem ammo still cycled the semi-auto AR-platform rifle perfectly well:
UltimateReloader.com Explains .223 Rem vs. 5.56x45mm
To explain the key differences between the .223 Rem and 5.56x45mm cartridges our friend Gavin Gear of UltimateReloader.com has created a very thorough 12-minute video. This covers the cartridge specifications and explains key considerations for hand-loaders. Gavin also addresses the oft-asked question “Can I shoot 5.56x45mm ammo in my .223 Rem chamber?” Gavin’s video is definitely worth watching. In fact, this is one of the most popular videos Gavin has ever created — it has been watched over 300,000 times on YouTube.
What Exactly Is the 5.56x45mm NATO Cartridge?
The 5.56×45mm NATO is a rimless bottle-necked intermediate cartridge family standardized by NATO with development work by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.
Bullet diameter: 5.70 mm (0.224 in)
Maximum pressure (EPVAT): 430.00 MPa (62,366 psi)
Maximum pressure (SCATP 5.56): 380.00 MPa (55,114 psi)
Case length: 44.70 mm (1.760 in)
Rifling twist: 178 mm or 229 mm (1 in 7 in)
Parent case: .223 Remington (M193)
Ammo-Maker Federal Premium Compares .223 Rem and 5.56x45mm
Here is a video from ammo-maker Federal Premium explaining the difference between .223 Remington and 5.56x45mm NATO. Federal states that you may experience excessive pressures when firing a 5.56x45mm in a standard .223 Remington chamber:
One leading gunwriter has addressed the question of shooting 5.56x45mm ammo in .223 Rem chambers. He advocates caution (for more info, SEE pressure tests by LuckyGunner.com):
“I have received a slew of questions — many from first time AR-type rifle buyers — about the .223 Rem and the 5.56×45 mm NATO cartridges. Can I shoot 5.56×45 mm NATO in my .223 and vice-versa? Are these the same cartridge?
Externally, the two cartridge cases are identical. The main differences are that 5.56×45 mm NATO operates at a higher chamber pressure (about 60,000 PSI versus 55,000 PSI on the .223 Rem.) and the 5.56’s chamber is slightly larger than that of the .223 Rem. Also, the throat or leade is longer in the 5.56×45 mm chamber. What does this mean? You should not shoot 5.56×45 mm NATO out of a rifle that is chambered in .223 Rem. And be aware that some .223 Rem. ammunition will not reliably cycle through some AR-style .223 Rem. rifles, but it usually does. As a matter of fact, I have not encountered any difficulty with current .223 Rem. loads cycling through a 5.56 mm AR-style rifle.” – Mark Keefe, Editor, American Rifleman
* According to the official NATO proofing guidelines, the 5.56×45mm NATO case can handle up to 430.0 MPa (62,366 psi) piezo service pressure. The U.S. SAAMI lists Maximum Average Pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa). The chamber for military 5.56×45mm NATO has a longer throat prior to the bullet contacting the rifling which results in lower pressures when firing 5.56×45mm NATO ammunition. If 5.56×45mm NATO is used in rifles chambered for .223 Remington the bullet will be engraving the rifling when chambered. which can increase pressures past SAAMI Max levels. NOTE: The C.I.P. standards for the C.I.P. civilian .223 Remington chamber are much closer to the military 5.56×45mm NATO chamber.
** The full-length LuckyGunner article is well worth reading. It even provides specifications for a number of .223 Rem reamer types, and compares the original .223 Rem, the 5.56x45mm NATO, and the modern .223 Wylde chamberings.

Our friend Gavin Gear of UltimateReloader.com was a busy man at SHOT Show 2020 in Las Vegas. He visited many leading vendors, and he also interviewed some of the most knowledgeable experts in the world of precision shooting. Today we present three important video interviews hosted by Gavin — the SHOT Show Brain Trust series.
First up is Bryan Litz, world-renowned ballistics expert and founder of Applied Ballistics LLC. The software developed by Bryan’s company is used by top competitive shooters and military marksmen. The second member of the Brain Trust is Emil Praslick III. Former Coach of the USAMU rifle team, Emil is considered to be one of the best wind-readers on the planet. Finally, we showcase a father and son team from New Zealand, Alex and Matt Finlay, developers of the Annealing Made Perfect (AMP) electrical induction annealing system.
Bryan Litz of Applied Ballistics LLC.
This interview with Bryan Litz is a “must-watch” for any serious long-range shooter. Bryan, founder of Applied Ballistics LLC., explains many important ballistics concepts. In addition Bryan discusses bullet design qualities that can reduce drag, increase BC, and improve bullet-to-bullet consistency.
Emil Praslick (U.S. Army Ret.) of Capstone Precision Group
Emil Praslick III, former coach of USAMU and USA Long Range teams, has been hailed as a “wind guru” — a master of wind reading. Emil now works for Capstone Precision Group, Parent of Berger Bullets, Lapua, Vihtavuori, and SK. In this wide-ranging interview, Emil talks about wind-reading strategies, modern bullet designs, and ballistics challenges in Long Range shooting.
Alex and Matt Finlay of Annealing Made Perfect (AMP)
Father Alex and son Matt Finlay have brought break-through technology to the world of precision hand-loading. Their innovative AMP annealing machines are true “game-changers” that extend useful case life and improve loading consistency. The computer-controlled AMP MK 2 annealing system is the most advanced and precise annealer available for the general consumer.
Comment from Interviewer Gavin Gear
It’s an absolute privilege to have access to the “best in the business”. I have so much respect for these innovators: Bryan Litz and Applied Ballistics, Emil Praslick: King of 2 Mile winning team member (2017), and the Annealing Made Perfect team (Alex and Matt). In each case, there’s very interesting innovation happening, and I’ve applied much of what I’ve learned from these people into my daily work on UltimateReloader.com.
Blue, Red, Green — There are many Progressive Press options on the market…
When you need ammo fast — lots of ammo, it’s hard to beat a progressive reloading press for output. We use progressive presses to load handgun ammo and .223 Rem cartridges for varmint safaris. With good dies, and proper press set-up, today’s progressive presses can produce surprisingly uniform and accurate ammo. No, you won’t see Benchrest Hall-of-Famers loading PPC cartridges on progressives. However, if you need 1000 rounds for your next prairie dog adventure, you should consider getting a progressive. Below you can see a Hornady Lock-N-Load AP configured to load .308 Winchester in bulk.
UltimateReloader.com has published helpful Tips to Optimize Progressive Rifle Loading. No matter whether you have a Red (Hornady), Green (RCBS), or Blue (Dillon) progressive, this article can help you load more efficiently and produce better results. Here are some highlights:
Proper Brass Prep
Just like a good paint job requires good prep work, great rifle ammo requires good brass prep. In order to make sure your rifle loading goes smoothly, make sure to perform the following brass prep steps:
Clean the brass (tumble, ultrasonic, etc.)
Inspect brass for cracks, deep dents, etc.
For military brass: de-prime, ream/swage primer pockets, size with small-base sizer die (small base usually optional).
Measure brass length — if too long, size and then trim.
Final inspection before loading.
Cleaning primer pockets may be something you’ll consider (I don’t clean primer pockets except for rare cases or match ammo).
Smooth and Steady Pace
Since you’re loading rifle ammunition on a progressive, you’re already saving a load of time, so there’s no need to rush things! Attention to detail is super-important for safety and for good results. Always keep an eye on powder level (goes down FAST) and what’s happening at each station.
The Right Press and Press Setup
Look for a heavy-duty, well-built press that will stand up to rifle loading. You’ll also want to make sure your powder measure will have the proper capacity (~25 grains for .223, ~50 grains for 308). If you are bulk reloading, ensure you have enough stations for sizing, charging, powder check, bullet feed, bullet seating, and (optional) bullet crimp. Compare the powder measuring systems, and give careful consideration to the priming process. You want case priming to be 100% reliable.
