Our good friends Ed and Steve (aka “The 6.5 Guys”) have just released an in-depth product review of the AMP Annealing system. Produced in New Zealand, the AMP (Annealing Made Perfect) unit is a sophisticated, microprocessor-controlled annealing machine that achieves ultra-consistent results through an electrical INDUCTION process.
AMP Annealing Machine Review by the 6.5 Guys:
Ed was so impressed with the AMP annealer that he purchased his own AMP to replace a carousel-type, dual-torch annealer he previously used. Ed tells us that “once you have the correct setting for your brass the AMP’s results are repeatable every time.” By contrast, Ed explained, “with butane torch systems you have to adjust the system when the ambient temperature changes, or even if your butane fuel is slightly different.” Ed says that, with his AMP system, he can anneal a case every few seconds. Yes it does require manually handling each case but “the actual annealing process is so fast, this really isn’t a big issue.”
If you want to extend the useful life of your precious cartridge brass, then you should definitely consider annealing. And if you are in the market for an annealer, the new AMP machine deserves serious consideration. Though not inexpensive, it achieves excellent results according to the 6.5 Guys.
6.5 Guys’ AMP Annealer Review Key Points:
1. The AMP machine provides complete peace of mind that you are annealing properly — there is no guesswork. With a propane machine you have to calibrate dwell times which can be error prone. Even if you don’t change out your cartridge, dwell times will vary with temperature changes as this affects the propane pressure.
2. We noticed that the AMP machine produces brass that is more like factory brass from a hardness standpoint. Despite all our efforts and research around calibrating our propane machines, brass never seemed returned to factory condition and shoulder spring-back would increase with each reloading so we had to adjust our sizing dies. When a cartridge comes out of the AMP it is very, very close to new condition.
3. One of the things we dreaded was setting up our propane machine for different cartridges. With Ed’s OCD he would spend a good 30 minutes making sure everything was perfect. With the AMP machine you simply change out the pilot and select the proper program. It’s really straight-forward.
NOTE: We strongly recommend you read the Full AMP Annealer Review on 65guys.com. It contains a detailed explanation of the machines’ operation and the reviewers explain the pros (and cons) or the machine compared to flame-type annealers.
The current price for the AMP Annealer, with three pilots of your choice, is $995.00 USD. Additional pilots are $20.00 USD. For more info, visit www.AMPAnnealing.com.
Guys — honestly, if you do anything today on this site, watch this video. You won’t be disappointed. Guaranteed. This is a very informative (and surprisingly entertaining) video. Every serious hand-loader should watch this video to see how cartridge cases are made. Your Editor has watched the video 5 times now and I still find it fascinating. The camera work and editing are excellent — there are many close-ups revealing key processes such as annealing and head-stamping.
VERY Informative Video Show Cartridge Brass and Ammunition Production:
Norma has released a fascinating video showing how bullet, brass, and ammunition are produced at the Norma Precision AB factory which first opened in 1902. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed (at multiple points along the case length) to check metal grain structure and hardness. Before packing, each case is visually inspected by a human being (3:27″ time-mark).
The video also shows how bullets are made from jackets and lead cores. Finally, you can watch the loading machines that fill cases with powder, seat the bullets, and then transport the loaded rounds to the packing system. In his enthusiasm, the reporter/narrator does sometimes confuse the term “bullets” and “rounds” (5:00″), but you can figure out what he means. We definitely recommend watching this video. It’s fascinating to see 110-year-old sorting devices on the assembly line right next to state-of-the art, digitally-controlled production machinery.

We’ve done some bullet casting in the past, both for handgun bullets, and the large, heavy (400gr+) projectiles used with Black Powder Cartridge Rifles. We can say, unequivocally, that newbies should seek out the assistance of a skilled, experienced mentor, who is familiar with the important safety procedures that must be employed. Working with molten lead can be dangerous. And it also takes some skill to get good results (without visible casting flaws), particularly with very large bullets.
That said, there are valuable resources that can help you get started with the casting process. Wolfe Publishing offers two DVDs that cover the bullet casting process from start to finish. Bullet Casting 101 takes you through the basics: showing you how to choose the correct alloy for your application, prep molds, maintain the optimal temperatures, and lube and size bullets. The important steps are laid out clearly. In addition, Bullet Casting 101 helps you select the right equipment and preferred molds for your particular application. (To create uniform rifle bullets that shoot accurately, you really do need high-quality molds.)
Wolfe Publishing offers a companion DVD, Casting Premium Bullets for Handguns, that covers more advanced techniques for high-volume pistol bullet production. This DVD covers both single-cavity molds and multiple-cavity “gang” molds. (Gang molds can be frustrating at first; it is harder to maintain perfect temp control and mold separation is more complex). The DVD also reveals the sources of most common casting flaws, and explains how to detect cracks, voids and other problems.
You’ll save considerable time and effort if you really understand how to avoid common mistakes before you start pouring lead. And you’ll get the best results if you learn how to “blend” the optimal alloy for the job. Maintaining the right mold temperature is also critical for good results. These topics and more are covered in these two DVDs, priced at $16.99 each from Sinclair International.

Made by Walther under license, these HK 416 D145RS rimfire rifles are accurate and reliable. This is a good deal at $379.99! The HK 416 normally sells for $550.00 to $600.00. One purchaser writes: “Great .22. I have had this gun a couple of months and have put about 500 rounds of 5 different brands of ammo through it. Not one FTE. I have shot other brands that can’t get through one 30-round mag without a failure.” CLICK HERE for Product Details.
Need quality .22 LR rimfire ammo at an affordable price? Consider Norma. Most folks think Norma only produces centerfire ammo and cartridge brass. As a result, people haven’t been looking for Norma rimfire ammo. Their loss is your gain. Accurate, reliable Norma .22 LR ammunition is in-stock right now at leading online vendors. This is good quality ammo, made in Europe. Bullets.com has Norma Tac-22 ammo in stock at $5.25 per 50-rd box (SKU: BL7819). In addition, Bullets.com offers Norma Match-22 ammunition at $7.50 per 50-rd box (SKU: BL11887).
6. Amazon — RAVPower 22000 mAh Battery Bank, $39.99
This is one of the most powerful, fast-charging USB-type power banks you can buy. Rated at 22000 mAh, it has 50% more “juice” than many units selling for around $35.00. This RAV Power machine charges up quickly and boasts three “intelligent” ports for optimal charging of smartphones, iPads, tablets, and other devices. After looking at a number of competitive battery banks, your Editor bought this RAVPower 22000 mAh unit to charge his own phone and iPad. It can deliver a total current output of 5.8A (2.4A max per port), allowing it to charge two iPads and one iPhone 6s at optimal charging speeds. This unit can also power a LabRadar Chronograph for a full weekend of shooting (6-7 hours per day).
Here is a very good deal on a decent 55-inch-high Stack-On Safe that offers a lot of capacity for the money. The claimed capacity is 24 long guns, that might work for smaller, unscoped rifles or shotguns. For scoped rifles, you might fit a dozen comfortably. There are convertible shelves that can hold handguns, optics, or other valuables. This safe will be delivered to your location — it is not available for in-store pick-up. Shipping surcharge applies. External Safe Dimensions are 55.00″ High x 29.25″ Wide x 20.25″ Deep. Shipping weight is 436 pounds.
For pure plinking fun, it’s hard to beat rimfire shooting at reactive targets. We’ve used this inexpensive Rimfire Spinner target, and it has proven easy to set up and durable. We like the fact that there are three target diameters (3 5/8″, 2 1/4″, 1 5/8″) — that let’s new shooters get their confidence. You can set this spinner target close for pistols or at 50 yards with .22 LR rifles. This Birchwood Casey Target is also offered by Amazon.com for $19.99 with FREE Prime Shipping.
Why You CANNOT Rely on the MV Printed on the Ammo Box!
When figuring out your come-ups with a ballistics solver or drop chart it’s “mission critical” to have an accurate muzzle velocity (MV). When shooting factory ammo, it’s tempting to use the manufacturer-provided MV which may be printed on the package. That’s not such a great idea says Bryan Litz of Applied Ballistics. Don’t rely on the MV on the box, Bryan advises — you should take out your chrono and run your own velocity tests. There are a number of reasons why the MV values on ammo packaging may be inaccurate. Below is a discussion of factory ammo MV from the Applied Ballistics Facebook Page.
Five Reasons You Cannot Trust the Velocity on a Box of Ammo:
1. You have no idea about the rifle used for the MV test.
2. You have no idea what atmospheric conditions were during testing, and yes it matters a lot.
3. You have no idea of the SD for the factory ammo, and how the manufacturer derived the MV from that SD. (Marketing plays a role here).
4. You have no idea of the precision and quality of chronograph(s) used for velocity testing.
5. You have no idea if the manufacturer used the raw velocity, or back-calculated the MV. The BC used to back track that data is also unknown.
1. The factory test rifle and your rifle are not the same. Aside from having a different chamber, and possibly barrel length some other things are important too like the barrel twist rate, and how much wear was in the barrel. Was it just recently cleaned, has it ever been cleaned? You simply don’t know anything about the rifle used in testing.
2. Temperature and Humidity conditions may be quite different (than during testing). Temperature has a physical effect on powder, which changes how it burns. Couple this with the fact that different powders can vary in temp-stability quite a bit. You just don’t know what the conditions at the time of testing were. Also a lot of factory ammunition is loaded with powder that is meter friendly. Meter friendly can often times be ball powder, which is less temperature stable than stick powder often times.
3. The ammo’s Standard Deviation (SD) is unknown. You will often notice that while MV is often listed on ammo packages, Standard Deviation (normally) is not. It is not uncommon for factory ammunition to have an SD of 18 or higher. Sometimes as high as 40+. As such is the nature of metering powder. With marketing in mind, did they pick the high, low, or average end of the SD? We really don’t know. You won’t either until you test it for yourself. For hand-loaded ammo, to be considered around 10 fps or less. Having a high SD is often the nature of metered powder and factory loads. The image below is from Modern Advancements in Long Range Shooting: Volume II.
4. You don’t know how MV was measured. What chronograph system did the manufacturer use, and how did they back track to a muzzle velocity? A chronograph does not measure true velocity at the muzzle; it simply measures velocity at the location it is sitting. So you need to back-calculate the distance from the chrono to the end of the barrel. This calculation requires a semi-accurate BC. So whose BC was used to back track to the muzzle or did the manufacturer even do that? Did they simply print the numbers displayed by the chronograph? What kind of chronograph setup did they use? We know from our Lab Testing that not all chronographs are created equal. Without knowing what chronograph was used, you have no idea the quality of the measurement. See: Applied Ballistics Chronograph Chapter Excerpt.
5. The MV data may not be current. Does the manufacturer update that data for every lot? Or is it the same data from years ago? Some manufacturers rarely if ever re-test and update information. Some update it every lot (ABM Ammo is actually tested every single lot for 1% consistency). Without knowing this information, you could be using data for years ago.
CONCLUSION: Never use the printed MV off a box of ammo as anything more than a starting point, there are too many factors to account for. You must always either test for the MV with a chronograph, or use carefully obtained, live fire data. When you are using a Ballistic Solver such as the AB Apps or Devices integrated with AB, you need to know the MV to an accuracy down to 5 fps. The more reliable the MV number, the better your ballistics solutions.

Coating bullets with a friction-reducing compound such as Molybdenum Disulfide (Moly) offers potential benefits, including reduced barrel heat, and being able to shoot longer strings of fire between bore cleanings. One of the effects of reduced friction can be the lessening of internal barrel pressures. This, in turn, means that coated bullets may run slower than naked bullets (with charges held equal). To restore velocities, shooters running coated bullets are inclined to “bump up” the load — but you need to be cautious.
Be Careful When Increasing Loads for Coated Bullets
We caution shooters that when your start out with coated bullets in a “fresh barrel” you should NOT immediately raise the charge weight. It may take a couple dozen coated rounds before the anti-friction coating is distributed through the bore, and you really start to see the reduced pressures. Some guys will automatically add a grain or so to recommended “naked” bullet charge weights when they shoot coated bullets. That’s a risky undertaking.
Instead we recommend that you use “naked” bullet loads for the first dozen coated rounds through a new barrel. Use a chronograph and monitor velocities. It may take up to 30 rounds before you see a reduction in velocity of 30-50 fps that indicates that your anti-friction coating is fully effective.
We have a friend who was recently testing moly-coated 6mm bullets in a 6-6.5×47. Moly had not been used in the barrel before. Our friend had added a grain to his “naked” bullet load, thinking that would compensate for the predicted lower pressures. What he found instead was that his loads were WAY too hot initially. It took 30+ moly-coated rounds through the bore before he saw his velocities drop — a sign that the pressure had lowered due to the moly. For the rounds fired before that point his pressures were too high, and he ended up tossing some expensive Lapua brass into the trash because the primer pockets had expanded excessively.
LESSON: Start low, even with coated bullets. Don’t increase your charge weights (over naked bullet loads) until you have clear evidence of lower pressure and reduced velocity.
Procedure After Barrel Cleaning
If you shoot Moly, and clean the barrel aggressively after a match, you may want to shoot a dozen coated “foulers” before starting your record string. Robert Whitley, who has used Moly in some of his rifles, tells us he liked to have 10-15 coated rounds through the bore before commencing record fire. In a “squeaky-clean” bore, you won’t get the full “benefits” of moly immediately.
To learn more about the properties of dry lubricants for bullets, read our Guide to Coating Bullets. This covers the three most popular bullet coatings: Molybdenum Disulfide (Moly), Tungsten Disulfide (WS2 or ‘Danzac’), and Hexagonal Boron Nitride (HBN). The article discusses the pros and cons of the different bullet coatings and offers step-by-step, illustrated instructions on how to coat your bullets using a tumbler.
