The Most Advanced Neck-Turners — Blake IDOD and AUTODOD

Bryan Blake machine f-class products IDOD AUTOIDOD neck turner turning power machine

Bryan Blake, a very clever machinist and gunsmith, has created an ultra-precise and speedy neck-turning machine. Bryan, who runs Blake Machine, Blake Barrel, and F-Class Products has created a system that uses twin precision cutter tips to turn case necks inside and out quickly and efficiently, with superior precision. This advanced IDOD Neck Turning Machine holds cases securely in a precision-machined spindle attached to an electric motor. Twin blades move precisely during the cutting process, milling the necks inside and out. The turned necks come out perfect every time, with the shoulders trimmed exactly (with doughnut removed) as well. If you turn hundreds of cases during a shooting season, you may want to consider getting an IDOD from F-Class Products. Bryan was able to turn 30 cases in just 6 minutes. And there is an even more advanced version, called the AUTODOD, shown in the last video below.

Our friend Erik Cortina recently visited Bryan Blake in Phoenix. Erik saw the IDOD in action and was impressed. Erik notes: “For a very long time, we have been turning brass the exact same way. Use a mandrel as a pilot and have a cutter with a specified gap go around the perimeter and turn the necks to specified thickness. The IDOD uses a technique called ‘pinch turning’ to turn the ID and the OD (IDOD) at the same time.” You can watch how it works in Erik’s video below (action starts at 7:55 time-mark):

The secret to the efficiency of the Blake IDOD is a vibration-free motor, high-mass case-holder, precision OD/ID-adjustable cutter, along with an advanced tracking system that moves the cutter heads towards the case neck (and back again) with absolute, 100% repeatable precision. Watch the video from 8:30 to 10:10 to see Bryan explain how to adjust the system for a perfect result.

This shows how to set up the IDOD Neck-turning machine for a particular cartridge type:

6mm Creedmoor Load Data from Sierra Bullets + BONUS

6mm Creedmoor 6.5 Creedmoor load data Sierra Bullets
NOTE: The 6mm Creedmoor now does have an official SAAMI specification. It is no longer just a wildcat.

Sierra Bullets Load Data 6mm Creedmoor reloading tips

Sierra Bullets has published load data for the 6mm Creedmoor cartridge, a necked-down version of the popular 6.5 Creedmoor. Sierra has released very comprehensive 6mm Creedmoor load data, covering fifteen (15) different bullets from 55 to 110 grains. NOTE: Hornady-brand brass was used for Sierra’s 6mm Creedmoor load tests, not the newer, stronger Lapua 6.5 CM brass with small primer pockets. Hand-loaders using Lapua 6.5 Creedmoor brass necked to 6mm may have to adjust their loads.

Sierra writes: “As soon as the 6.5 Creedmoor was released in 2007, a 6mm version was being envisioned. After the 6mm Creedmoor demonstrated its worth at 1000 yards it began to catch the attention of Precision Rifle Series (PRS) competitors. The 6mm Creedmoor is a great fit for those looking for an AR platform-friendly cartridge. It delivers velocities very similar to the .243 Win and yet fits the AR10 magazine length[.] The 30-degree shoulder makes this a very efficient case and helps prolong case life as well. The 6mm Creedmoor works well with powders such as H4350, [RE-16], RE-17, and Ramshot Hunter for heavier long-range bullet weights. Slightly faster powders such as RE-15, Win 760, and Vihtavuori N540 work well with lighter weight bullets.”

100gr Spitzer (#1540)
100gr SBT (#1560)
107gr HPBT (#1570)
110gr HPBT (#1575)

In developing its 6mm Creedmoor load data, Sierra tested a very wide selection of propellants, two dozen overall. For the smaller bullets, fast-burning powders such as Benchmark, H4895, and CFE223 were tested. For the heavier 100+ grain bullets, Sierra tested a selection of medium-burn-rate powders including H4350, Reloder 16, Reloder 17, Varget, and Superformance. Sierra did a very thorough job. We know this information will be welcomed by 6mm Creedmoor shooters.

Don’t know what powder to try first? For the 107-110 grain bullets, if you want best accuracy and low ES/SD, our Forum members recommend Alliant Reloder 16 and Hodgdon H4350. If you are seeking max velocity with the 110-grainer, look at Hodgdon Superformance and Reloder 19.

Here are Sierra’s 6mm Creedmoor Load Data Charts for 90-95 grain bullets plus the 107gr MK and 110gr MK. There are five other tables for other bullet types.

Click-Adjust FL Die Systems from PMA Tool & Whidden Gunworks

click-adjustable die micro-adjusting lock ring PMA Tool Whidden Gunworks

One of the most important aspects of precision reloading is setting the shoulder bump during the full-length (FL) sizing process. You want the amount of “bump” to be precise and identical for every loaded round. However, when you switch brands of brass you may need to change the die position to get the desired bump and case body sizing. And even with the same brand of brass, you may find that you need to adjust your FL die as the number of brass load cycles increases. Brass that has been fired many times will behave differently than new or near-new brass.

Also, even with the same cartridge type, brass loaded for a semi-auto rifle may need more bump than brass fired in a bolt gun. For example, with .223 Rem ammo, you’ll normally want to push the shoulder back farther if the ammo will be shot in a AR15 as opposed to a bolt-action rig.

So how do you make all these needed adjustments for your full-length dies? You can move a conventional locking ring up and down, but that can be a tedious, trial-and-error process. Some guys use shims in one-thousandth intervals, but that still requires taking your dies in and out of the press. Well there is a better way now…

PMA Tool Micro-Die Adjuster

Wouldn’t it be great if you could precisely adjust your FL die up and down in half-thousandth increments, with a simple indexed click. That is now possible with products offered by PMA Tool and Whidden Gunworks. PMA Tool offers a Micro-Die Adjuster that replaces your existing lock ring and can be used with nearly any 7/8-14 full length sizing die. The engraved marks correspond to approximately .001″ of shoulder bump adjustment. Splitting the engraved marks is therefore approximately equal to .0005″ (half a thousandth). Users love this product, saying it adds precision and saves time.

Whidden Click-Adjustable FL Sizing Die System

Whidden Gunworks offers a complete click-adjustable FL sizer die with a special, indexed ring. With Whidden’s patent-pending Click Adjustable Sizer Die system, the die and lock ring work together to allow rapid, precise bump adjustments. One click changes the bump .001″. It’s simple and fast. Included with the Click Adjustable Sizer Die is a shoulder bump gauge. John Whidden (in video below) explains:

“There has become a need for an easier way to adjust the sizer die properly. Until now there have been few options other than trial and error to get the shoulder setback correct. Anyone who has done this can attest that it’s a slow and imprecise job! Our die and lock ring work together to give the user a clicking feel to the adjustment. Each click moves the shoulder bump .001” so you can easily find the exact shoulder bump that you desire.” — John Whidden

Smarter Reloader — Use Expander Mandrels with Your New Brass

Expander Mandrel reloading case neck tension cartridge brass

Before you load that nice new cartridge brass for the first time, run an expander mandrel down the case necks. This will iron out dents and provide more uniform neck tension. Chose a mandrel diameter that provides appropriate neck tension.

Lapua brass is so good that you’ll be tempted to just load and shoot, if you have a “no-turn” chamber. However, some minimal case prep will ensure more uniform neck tension. Keeping your neck tension very uniform allows more consistent bullet seating. That, in turn, usually yields better accuracy, and lower Extreme Spread and Standard Deviation (ES/SD). Lapua brass, particularly 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win comes from the factory with tighter-than-optimal necks. Before you seat bullets, at a minimum, you should inside chamfer the case mouths, after running an expander mandrel down the necks. The expander mandrels from both Sinclair Int’l and K&M will both leave the necks with enough neck tension (more than .001″) so you can then seat bullets without another operation. We suggest putting a bit of lube on the mandrel before running it down the necks — but remove any lube that gets inside the necks before seating bullets.

Sinclair Expander Tool Mandrel

Both Sinclair and K&M Tools make a die body specifically to hold expander mandrels. The Sinclair version, is shown above. This $32.99 unit fits caliber-specific expander mandrels ($9.99) which measure approximately .001″ less than bullet diameter for each caliber. This is an updated “Gen II” design that completely captures the mandrel within the die so the mandrel cannot pull out. It also has an O-ring in the die cap that allows the mandrel to self-center within the case neck. Sinclair now offers three sizes of die bodies for expander mandrels: .17 -.338 Caliber (#749-011-715WS $32.99); .357 – .50 caliber (#749-008-843WS, $32.99), and a special .50 Cal die body for large-diameter 50 BMG presses (#749-009-163WS, $39.99). All Generation II dies are machined from stainless steel and the standard diameter 7/8-14 dies include the Sinclair Stainless Steel Split Lock Ring.

Once you run the Sinclair expander mandrel down the necks of Lapua brass, after you account for brass spring-back, you’ll have about .002″ neck tension*. This will make the process of seating bullets go much more smoothly, and you will also iron out any dents in the case mouths. Once the case mouths are all expanded, and uniformly round, then do your inside neck chamfering/deburring. The same expander mandrels can be used to “neck-up” smaller diameter brass, or prepare brass for neck-turning.

Forum member Mike Crawford adds: “These expanders can also reduce runout from offset seating. Prior to bullet seating, expand the sized necks to force thickness variance outward. With the Sinclair system, the necks will springback fine, and will not be pulled out of center. This leaves plenty of tension, and bullets seated more centered. I do this, even with turned necks, to get improved seating.”

Mandrels vs. Expander Balls on Decapping Rods
If you haven’t acquired an appropriate expander mandrel for your brass, but you DO have a full-length sizing die with an expander ball, this will also function to “iron out” the necks and reduce tension. However, using a die with an expander ball will work the necks more — since you first size them down, then the ball expands them up again. Typically (but not always), run-out is worse when using an expander ball vs. an expander mandrel.


* This .002″ tension is what we have observed with Lapua 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win brass. This might vary with much smaller or larger cases, and of course a different brand of brass might yield different results. If you get too little tension with your current mandrel, you can get a smaller-diameter mandrel from 21st Century Shooting. 21st Century even offers low-friction Titanium Nitride-coated mandrels.

AutoTrickler V3 Tips — Set-up, Optimization, Maintenance

Adam MacDonald Autotrickler v3 autotrhow powder dispenser video F-Class john

Top rifle competitors use the AutoTrickler system because it offers a superior combination of speed and precision in dispensing powder loads. With an AutoTrickler fitted to a compatible lab-grade magnetic force restoration scale, you can achieve single-grain weight consistency with your hand-loads. That kind of load weight uniformity does help deliver low ES/SD that translates to reduced vertical at long range. Adam MacDonald’s AutoTrickler system is so good that it can truly be called a “game-changer” in the precision handloading world.

As good as the AutoTrickler may be, there are some simple ways to keep it functioning better, or to improve your productivity. Here are three videos by F-Class John that provide very helpful tips for AutoTrickler owners. The first video shows general set-up and installation. The second video shows a simple but brilliant trick to speed up the process — use two identical powder measure cups shaved to be the EXACT same weight. In third video, F-Class John shows important maintenance tips to keep your AutoTrickler components running smoothly and quietly.

AutoTrickler V3 — General Set-Up and Operational Advice

In this video, John offers some general advice for setting-up the AutoTrickler system. He explains how you can get the machine optimized. For example he notes that you want to set the initial drop weight (from the powder measure) in an optimal range: “When you set the original drop you need it to be about 1 to 1.5 grains below. Some people set it too close to the final weight they want and it actually doesn’t let the trickler unit work as efficiently, consistently and accurately as it will if you start 1 to 1.5 grains low.”

John also explains how to hook up the cords and how to position the trickler unit. John places his AutoTrickler on a 30-lb piece of granite, with a thin polymer “anti-static” pad on top. John also uses a line conditioner and grounding wire to provide the best electrical flow to the scale and trickler. Interestingly, the granite was an inexpensive “surplus” piece taken from a kitchen top installation.

John also shows how the angle of the trickler unit can be adjusted. Another smart tip involves marking the white trickler tube belt bushing. That makes it is easier to discern slow movement and determine when the trickler is completely stopped.

If you own an AutoTrickler or plan to purchase one, we definitely recommend you watch this entire video.

Are you experience chattering when powder is dispensed? John also explains (3:20 – 5:30 time mark) how to replace a small rubber “wiper” part in the dispenser unit. This can help prevent chattering or kernel-cutting as the powder charge drops into the pan from above.

Use Two Identical-Weight Powder Cups to Load Faster

In this second video, F-Class John shows how you can use TWO identical powder cups to speed up your reloading. This is a VERY clever and relatively inexpensive upgrade. You can use 600-grit wet sandpaper to make the weight of the twin cups absolutely identical. John says: “I just lightly sanded the bottom of these until they both weighed exactly the same on my scale.” He can now use one cup to load a case while the other cup is receiving the next powder charge.

AutoTrickler V3 General Maintenance Tips

If you have been running an AutoTrickler for quite some time, you have probably noticed some noise or vibration. This video shows some very simple maintenance procedures that will have your AutoTrickler running great again. F-Class John reveals some components that can get dirty or worn after considerable use. The video identifies the items that may require a cleaning or adjusting. In the video John shows how to do those tasks quickly and easily.

Adam MacDonald Autotrickler v3 autotrhow powder dispenser video F-Class john

In the last three minutes of the above video John shows an important process involving the trickler unit motor. The motor’s attachment screws tend to loosen slightly over time. After removing the pulley drive wheel, you want to gently tension the four Phillips screws. Then reattach the wheel and drive belt. Doing this simple process should reduce unwanted vibration.

Variances in Load Data — Why Load Manuals Don’t Always Agree

load manual sierra reloading hornady data

Written by Sierra Bullets Ballistic Technician Duane Siercks
One of the first things new reloaders notice is that load data varies between reloading manuals. The Sierra Bullets Technicians frequently get inquiries asking us to explain why the load data appears to be inconsistent. This article explains five key factors that can influence published load data.

Example of load data variances for two 168 grain bullets:

Sierra Reloading Manual Hornady Load Reloading

Here are five reasons why the load data varies:

The Bullet
Basically, the similarities in the .30 caliber 168 grain Match bullets (for example) end with weight and diameter. The bullets likely have dimensional differences such as bearing surface length. Bearing surface has a large effect on pressure and velocity. There are also differences in boat tail, flat base, ogive and over-all lengths, which each help determine the cartridge over-all-length (COAL). With different COAL’s, we can expect changes in pressure and velocity also. In some calibers there are differences in bullet diameter with different bullet manufacturers.

It is also worth noting that bullet manufacturers do not all use the same copper alloy for their jackets. This produces more or less friction that results in load pressures and velocities. The solid copper bullets also vary quite a bit in comparison to a lead core and copper jacketed bullet.

The Gun
Each gun is unique, even if you are using the same make, model, and caliber. Special consideration should be used to consider that not all firearm chambers are the same either, creating more variables that need consideration. There can be drastic differences in the throat length. This controls the amount of “jump” that a bullet experiences when the cartridge is fired.

The Powder
Within normal manufacturing tolerances, you can see some variation in a given powders burn rate between different lots of the same powder. So naturally when two different Manuals are produced, it would be doubtful that the same lots would be tested.

The Cartridge Cases
New cases are almost always near minimum specs in dimension. A load fired in a new case would likely have slightly more pressure that when fired in a re-sized case. This would certainly be true if we were loading into fire-formed cases that have had minimal re-sizing done. Fired cases that are full length resized most of the time be slightly larger than the new unfired cases. This gives you differences in case capacity. The same powder charge placed within a new case and a full length resized case will produce different pressure levels and probably different velocities.

Conditions
Temperature can cause pressure increases or decreases. Hot temperatures tend to cause pressures to increase, while cold temperatures will usually do the opposite. Humidity and altitude can impact pressures and velocities likewise.

Conclusion
As you can see, an amazing number of variables effect any load combination. With the differences in the manuals, you’re just seeing firsthand examples of what took place when the data was collected with that particular set of components and firearm. Think of a reloading manual as a report. In essence, a reloading manual says, “We tried this particular component combination, and these are the results we obtained.”

Remember that you may or may not reach the same maximum load safely. There is no “one load fits all bullets.” The minimum load data offers a safe place to start. The maximum load data listed should always be regarded as a safety guideline and not necessarily a goal! Your gun should shoot accurately without breaching the maximum load data. The best advice is: always start low and work your load up!

If you have questions about variances in load data or other reloading questions, please call our ballistic technicians at 1-800-223-8799 or send us an email at sierra [at] sierrabullets.com.

Reloder 23 and Reloder 26 — Good for Magnum Cartridges

Alliant Bofors Nitrochemie Reloader Reloading RL Reloder powder 22 23 25 26

Do you shoot a magnum cartridge? Here are two modern-formulation powders you may want to try: Reloder 23 and 26. We have been particularly impressed with Reloder 23. It has worked well in competition for target cartridges such as the 7mm RSAUM. Reloder 23 is like a slower version of Reloder 16 — a very temp-stable powder which has proven a worthy rival to H4350.

Ever heard of Alliant Reloder 23? Or Reloder 26? These two relatively new European-produced Reloder propellants were introduced in 2014. Most folks haven’t tried these Reloder powders because it took quite a while for the first shipments of RL 23 and RL 26 to arrive in the USA. But now these two new propellants are available in the USA, with substantial inventories in stock at some larger vendors. For example, Powder Valley has both RL 23 and RL 26 in stock now at $23.50 per pound. Many other vendors have ample RL 23, but RL 26 is a bit harder to find.

From our Forum members who shoot large magnum cartridge types with heavy bullets, we have heard good things about both RL 23 and RL 26. Reports from the field indicate that both these powders are delivering impressive velocities with low velocity ES/SD.

What are the characteristics of RL 23 and RL 26? That question was answered by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:

“Let me provide some factual info about these products. Some of the stuff that gets propagated is not correct. Reloder 23 is produced by our Swedish partner Bofors, and Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they are both made by Bofors, so that is incorrect.

I have also noticed people are equating Reloder 23 to Reloder 22, and Reloder 26 to Reloder 25. Both of those statements are definitely incorrect. We do state that the performance of Reloder 23 is similar to Reloder 22, and it is, in general burn speed terms, but they are most certainly not the same. We have worked quite a lot of recipes for Reloder 23, and they are not the same as Reloder 22. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”

Furrier says that RL 23 is NOT sensitive to temperature shifts: “Reloder 23 was developed to bring a truly temp-stable powder to the Reloder 22 burn-speed range using Bofors new process technology. This is the second product developed for us with this TZ® process, the first being AR-Comp™. We see terrific efficiencies, SDs, accuracy and flat temp response from these powders. Please try them, I think you will be impressed.”
