Here is a simple technique that can potentially help you load straighter ammo, with less run-out (as measured on the bullet). This procedure costs nothing and adds only a few seconds to the time needed to load a cartridge. Next time you’re loading ammo with a threaded (screw-in) seating die, try seating the bullet in two stages. Run the cartridge up in the seating die just enough to seat the bullet half way. Then lower the cartridge and rotate it 180° in the shell-holder. Now raise the cartridge up into the die again and finish seating the bullet.
Steve, aka “Short Range”, one of our Forum members, recently inquired about run-out apparently caused by his bullet-seating process. Steve’s 30BR cases were coming out of his neck-sizer with good concentricity, but the run-out nearly doubled after he seated the bullets. At the suggestion of other Forum members, Steve tried the process of rotating his cartridge while seating his bullet. Steve then measured run-out on his loaded rounds. To his surprise there was a noticeable reduction in run-out on the cases which had been rotated during seating. Steve explains: “For the rounds that I loaded yesterday, I seated the bullet half-way, and turned the round 180 degrees, and finished seating the bullet. That reduced the bullet runout by almost half on most rounds compared to the measurements from the first test.”
Steve recorded run-out measurements on his 30 BR brass using both the conventional (one-pass) seating procedure, as well as the two-stage (with 180° rotation) method. Steve’s measurements are collected in the two charts above. As you can see, the run-out was less for the rounds which were rotated during seating. Note, the change is pretty small (less than .001″ on average), but every little bit helps in the accuracy game. If you use a threaded (screw-in) seating die, you might try this two-stage bullet-seating method. Rotating your case in the middle of the seating process won’t cost you a penny, and it just might produce straighter ammo (nothing is guaranteed). If you do NOT see any improvement on the target, you can always go back to seating your bullets in one pass. READ Forum Thread.
This article comes from the Bryan Litz Ballistics Facebook page. That page offers valuable tips on ballistics, marksmanship, and precision reloading, with updates nearly every day of the year. One recent post relates to velocity changes that can occur when traveling away from home.
Q: Is there a physical reason, other than temperature, why sometimes we see a difference in muzzle velocity when we travel to a different location?
Bryan Litz notes: “One reason we found for this is powder humidity. We put out a video on our YouTube channel called “Powder Humidity / Temperature and Storage”. Watch the video below to learn more specifics about the effects of humidity and temperature changes on your loaded ammunition.
Basically, if you develop a load at home, then travel to a dramatically different environment (drier or wetter), and your ammo isn’t hermetically sealed, it can affect the powder burn rate. This can cause muzzle velocity to change.
Humidity Field Tests with 6.5 Creedmoor and H4350
To learn more about the effects of humidity on velocity and ammo performance, we recommend another article found on the ChronoPlotter.com website. This article begins by reviewing research done by Applied Ballistics, Norma, and Vihtavuori.
Then author Michael Coppola covers his extensive experiments with Hodgdon H4350 powder stored with different relative humidity (RH) levels then loaded in 6.5 Creedmoor rounds. The results were quite dramatic: “At its lowest humidity (14.5% RH), our 41.50 gr H4350 charge clocked in at an average 2,879 fps, peaking at 2,901 fps. Its highest humidity (83.5% RH) saw an average of 2,650 fps with a lowest velocity of 2,635 fps. The entire experiment saw an Extreme Spread of 266 fps. Between the desiccated and 66.5% samples, a 10% change in RH resulted in a velocity change of about 25.6 fps. Above 66.5%, this effect nearly doubled and a 10% change in RH resulted in a change of about 57 fps.
The 6.5 Creedmoor cartridge has become extremely popular in the last few years. It is a popular cartridge among PRS and tactical competitors, and has been used successfully by deer hunters and silhouette shooters. Notable major manufacturers such as Ruger and Savage are selling popular rifles chambered for this mid-sized cartridge. The availability of affordable factory rifles chambered in 6.5 Creedmoor further fuels its popularity.
To mark the popularity of the 6.5 Creedmoor, we’ve sourced five videos from YouTube. These videos cover loading for the 6.5 Creedmoor and also test accuracy in both custom and factory rifles. Enjoy this 6.5 Creedmoor Video Fest:
1. Gas Gun Shoot-Out: 6.5 Creedmoor vs. .308 Win
In this TFB TV video, testers put a 6.5 Creedmoor up against a .308 Winchester with AR-10 type rifles. The head-to-head test compares the ballistics, trajectory, recoil, and inherent accuracy of the two popular cartridge types. We can’t call this a definitive test because most 6.5 Creedmoor shooters run bolt-action rifles. The key take-aways are that the 6.5 Creedmoor has significantly less recoil, and a flatter trajectory (at least with typical factory ammo). Still, the video is a good starting point for anyone considering a gas gun in 6.5 Creedmoor.
2. Ruger Precision Rifle with Norma 6.5 Creedmoor Ammo
In this video Gavin Gear tests Norma-brand factory ammo in a Ruger Precision Rifle chambered in 6.5 Creedmoor. Gavin reports: “Norma is known for its high-quality brass and ammunition. Recently, I saw that Norma had announced a new addition to their Professional Hunter lineup of ammunition: in 6.5 Creedmoor! I thought I should try some out with the Ruger Precision Rifle. As you saw in the video, this ammunition behaves more like match ammunition.”
3. 6.5 Guys Test Lapua 6.5 Creedmoor Brass in Tactical Rifles
If you have a 6.5 Creedmoor rifle, or are considering getting a gun chambered for this cartridge, we strongly recommend you watch the full 6.5 Guys Video. Ed and Steve spent a lot of time conducting this test, and the video includes helpful summaries of their findings.
4. Reloading for the 6.5 Creedmoor — Gear and Components
If you own a 6.5 Creedmoor rifle, and plan to start hand-loading for the popular cartridge, this video may help you select effective load components. The video examines a wide variety of brass, powder, and bullets options for the cartridge. In addition the reviewer looks at various reloading dies and tools suitable for 6.5 Creedmoor hand-loading.
5. The Springfield Armory M1A — Now Offered in 6.5 Creedmoor
Many folks may not realize that Springfield Armory now makes an M1A chambered in 6.5 Creedmoor. With considerably less recoil, this 6.5 CM version is easier to shoot than the classic 7.62×51 M1A: “Having a 6.5 Creedmoor caliber in the M1A lineup gives long-range shooters more choices with the precision and accuracy they require,” says Springfield Armory CEO Dennis Reese.

There are many products used successfully for case lubrication for case sizing. And for neck-turning a variety of lubricants are favored. The video above explains the basics of case lubrication with die wax, and spray lubricants. Below we mention three products that have proven very effective. For cases that have a close fit to your chamber via custom FL dies, Ballistol works well and is easy to apply and remove. For neck-turning, some of our Forum members have had great success with some automotive lubricants.
Three Good Lubricants You May Not Have Tried Before If you’re using a body die or a full-length sizing die, try using Ballistol (in the aerosol can) as a lube. It works GREAT without the tacky or gooey residue left by most case lubes. It will also clean off carbon residues on the neck as you lube the case. Just spray a little on a cotton patch (or your fingertips) and wipe each case before you run it up into the die. If you are using a steel neck bushing, be sure to wipe the neck as well. You can usually do a half-dozen BR-sized cases before you need to re-apply Ballistol on the patch. Ballistol is non-toxic, bio-degradeable, and will not harm your skin. It is very slippery, but can easily be removed with a rag or paper towel. Try it–you may retire your One-Shot. Ballistol can also be used to protect wood stocks.
Note, for heavy case-forming or necking up case necks, we still recommend a thicker lubricant, such as Imperial Die Wax. But for normal case sizing, after your neck has been expanded, Ballistol will do the job, and you won’t need to tumble the brass afterwards. All you need is a very thin layer of Ballistol, and this easily wipes off with a paper towel.
For Neck-Turning, Try STP Blend or Assembly Lube
For lubing the neck-turning tool mandrel while turning case necks, many folks use a blend of STP® Oil Treatment and Mobil 1 lube. Chuckw2 reports: “Try STP and Mobile 1 Synthetic oil in a 50/50 mixture. Very slick, you will need to tumble your cases after turning.” STP is a very thick lubricant, that flows and clings almost like honey. Jason reports the STP blend comes off easily in an ultra-sound bath, using a bit of detergent. At many retailers, STP is also available in a convenient 7-ounce tube, so you don’t have to buy a large bottle.
Another even cheaper option is assembly lubricant. For turning his case necks, RStreich uses assembly lube from an auto parts store. He notes: “The brand I have is reddish in color and kind of sticky like honey. It’s far better than the Imperial die wax I was using before.” There are a variety of types, both with and without moly additive, and you can select the viscosity you prefer if you sample a few brands. Be sure to clean out any lube residue from the inside of your necks when you have completed your neck-turning.
With hunting season in full swing, many folks will be shooting factory hunting ammunition. In setting scope elevation clicks for various distances, it would seem logical to use the velocity listed on the ammo box with your ballistics App or drop chart. But that could be a problem. You SHOULD still chronograph the ammo to determine its true muzzle velocity (MV) in your rifle. Read on to understand why.
Why You CANNOT Rely on the Muzzle Velocity
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.
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.

In some areas of the country (California in particular), hunters are now forbidden to use bullets that contain lead. If you need a lead-free projectile for your deer rifle, consider Nosler’s E-Tip projectile. This has plenty of penetrating power and retained energy while complying with laws requiring “unleaded” ammunition. An “expansion chamber” behind the green polymer tip helps ensure reliable expansion with 95% weight retention. The video below shows a .30 caliber, 180gr lead-free E-Tip impressively power through TWO 12-inch blocks of Ballistics Gel at 100 yards. This was fired from a .308 Winchester.
Watch 180gr eTip Penetration and Expansion in Ballistic Gelatin:
Nosler claims the E-Tip (“Expansion Tip”) bullet has advantages over other solid copper hunting bullets: “Unlike the competitor’s one-piece designs, Nosler E-Tip bullets will not blow the petals off at extreme velocities nor will the low end expansion ever be questioned, as the minimum impact velocity is set at 1800 fps for standard calibers.” One hunter, posting on Facebook, gave the E-Tip high marks: “I have had the opportunity to take a pig with a 130 gr E-Tip from my .270 and they work flawlessly. My son took two pigs with his .300 Win Mag and 165gr E-Tips and they worked flawlessly as well.”
This video illustrates the design and construction of the Nosler eTip Bullet:
Before you load that 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 (Brownells, $14.99 stainless, $24.99 Titanium Nitride coated) 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. If you do a lot of loading you may benefit from a Titanium Nitride-coated mandrel.
Both Sinclair and K&M Tools make a die body specifically to hold expander mandrels. The $61.99 Sinclair version fits caliber-specific expander mandrels 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. Brownells offers two sizes of Sinclair die bodies for expander mandrels: .17 -.338 caliber (#749011715 $61.99); and .357 – .50 caliber (#749008843, $49.99). 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 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 Innovation, with stainless, Black Nitride, or Titanium nitride versions. The Nitride models have less friction.
