6mm Creedmoor Load Data from Sierra Plus PRB 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 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.

Legendary Indoor Accuracy — Secrets of the Houston Warehouse

houston warehouse 6ppc secrets
Kelbly Light Varmint PPC Rifle from Gunbroker.com.

From the late ’70s through 1983, a huge, concrete-walled warehouse in Houston was used for benchrest testing. Virgil King and Bob Fisher set up a bullet-catching backstop at the end of a 30-yard-wide, 325-yard-long fire lane that remained unobstructed even when the warehouse was in use. This allowed accuracy tests in virtually perfect “no wind” conditions. Over a six-year period, about 30 shooters were invited to test their rifles. The results were amazing, with numerous “zero groups” being shot in the facility. Many of the lessons learned in the legendary Houston Warehouse still help benchresters achieve better accuracy today.

Dave Scott wrote a superb article, the Secrets of the Houston Warehouse which appeared in a special issue of Precision Shooting Magazine. That issue has long been sold out, but, thankfully, Secrets of the Houston Warehouse is now on the web: CLICK HERE to READ Secrets of the Houston Warehouse.

Houston WarehouseDave Scott explains why the Warehouse was so unique:

“Over a period of six years, the levels of accuracy achieved in the Houston Warehouse went beyond what many precision shooters thought possible for lightweight rifles shot from sandbags and aimed shot-to-shot by human eye. For the first time, a handful of gifted, serious experimenters — armed with the very best performing rifles (with notable exceptions) — could boldly venture into the final frontiers of rifle accuracy, a journey made possible by eliminating the baffling uncertainties of conditions arising from wind and mirage. Under these steel skies, a shooter could, without question, confirm the absolute limits of accuracy of his rifle, or isolate the source of a problem. In the flawlessly stable containment of the Houston Warehouse … a very few exceptional rifles would display the real stuff, drilling repeated groups measuring well below the unbelievably tiny .100″ barrier. The bulk of rifles, however, embarrassed their owners.”

Scott’s article also reveals some interesting technical points: “One thing that IS important is that the bullet be precisely seated against the lands. T.J. Jackson reported this fact in the May 1987 issue of Precision Shooting. In a letter to the Editor, T.J. wrote, ‘…in all our testing in that Houston warehouse… and the dozens and dozens of groups that Virgil King shot in there ‘in the zeroes’… he NEVER fired a single official screamer group when he was ‘jumping’ bullets. All his best groups were always seated into the lands, or at the very least… touching the lands. Virgil said his practice was to seat the bullets so the engraving was half as long as the width of the lands. He noticed an interesting phenomenon with rifles that could really shoot: if the bullets were seated a little short and the powder charge was a bit on the light side, the groups formed vertically. As he seated the bullets farther out and increased the powder charge, the groups finally became horizontal. If he went still farther, the groups formed big globs. He said the trick is to find the midway point between vertical and horizontal. That point should be a small hole.”

You should definitely read the complete article, as it provides many more fascinating insights, including shooting technique, barrel cleaning, neck-turning, and case prep.

EDITOR: Will the lessons of the Houston Warehouse work elsewhere? Is this repeatable magic? We remind readers that what T.J. Jackson discovered worked for his barrels, his cartridge type, and his choice of bullets. Jumping bullets can definitely produce good results in other cartridge types with bullets such as Berger Hybrids. Still, the Houston results are intriguing. Any time someone shoots in the “zeros” one should pay attention to how that was achieved.

Cartridge Efficiency — Factors to Consider

USAMU Handloading Guide Facebook cartridge efficiency

Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion.

USAMU Handloading Guide Facebook cartridge efficiency

Cartridge Efficiency: A Primer (pun intended!) by USAMU Staff

The U.S. Army Marksmanship Unit (USAMU) published a series of reloading articles on its Facebook Page. In this article, the USAMU discusses cartridge case efficiency and its benefits. While this is oriented primarily toward NRA High Power Rifle and Long Range (1000-yard) competition, these factors also apply to medium/big game hunters. Assuming one’s rifle and ammunition are accurate, key considerations include ballistic performance (i.e., resistance to wind effects, plus trajectory), recoil, and throat erosion/barrel life.

Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion. A classic example in the author’s experience involved a featherweight 7x57mm hunting/silhouette rifle. When loaded to modern-rifle pressures, just 43-44 grains of powder pushed a 139gr bullet at 2900 fps from its 22” barrel. Recoil in this light rifle was mild; it was very easy to shoot well, and its performance was superb.

An acquaintance chose a “do everything” 7mm Remington Magnum for use on medium game at short ranges. A larger, heavier rifle, it used ~65 grains of powder to achieve ~3200 fps with similar bullets — from its 26″ barrel. Recoil was higher, and he was sensitive to it, which hampered his shooting ability.

Similarly efficient calibers include the 6mm BR [Norma], and others. Today’s highly-efficient calibers, such as 6mm BR and a host of newer developments might use 28-30 grains of powder to launch a 105-107gr match bullet at speeds approaching the .243 Winchester. The .243 Win needs 40-45 grain charges at the same velocity.

Champion-level Long Range shooters need every ballistic edge feasible. They compete at a level where 1″ more or less drift in a wind change could make the difference between winning and losing. Shooters recognized this early on — the then-new .300 H&H Magnum quickly supplanted the .30-06 at the Wimbledon winner’s circle in the early days.

The .300 Winchester Magnum became popular, but its 190-220gr bullets had their work cut out for them once the 6.5-284 and its streamlined 140-142gr bullets arrived on the scene. The 6.5-284 gives superb accuracy and wind performance with about half the recoil of the big .30 magnums – albeit it is a known barrel-burner.

Currently, the 7mm Remington Short Action Ultra-Magnum (aka 7mm RSAUM), is giving stellar accuracy with cutting-edge, ~180 grain bullets, powder charges in the mid-50 grain range and velocities about 2800+ fps in long barrels. Beyond pure efficiency, the RSAUM’s modern, “short and fat” design helps ensure fine accuracy relative to older, longer cartridge designs of similar performance.

Recent design advances are yielding bullets with here-to-fore unheard-of ballistic efficiency; depending on the cartridge, they can make or break ones decision. Ballistic coefficients (“BC” — a numerical expression of a bullet’s ballistic efficiency) are soaring to new heights, and there are many exciting new avenues to explore.

The ideal choice [involves a] balancing act between bullet BCs, case capacity, velocity, barrel life, and recoil. But, as with new-car decisions, choosing can be half the fun!

Factors to Consider When Evaluating Cartridges
For competitive shooters… pristine accuracy and ballistic performance in the wind are critical. Flat trajectory benefits the hunter who may shoot at long, unknown distances (nowadays, range-finders help). However, this is of much less importance to competitors firing at known distances.

Recoil is an issue, particularly when one fires long strings during competition, and/or multiple strings in a day. Its effects are cumulative; cartridges with medium/heavy recoil can lead to shooter fatigue, disturbance of the shooting position and lower scores.

For hunters, who may only fire a few shots a year, recoil that does not induce flinching during sight-in, practice and hunting is a deciding factor. Depending on their game and ranges, etc., they may accept more recoil than the high-volume High Power or Long Range competitor.

Likewise, throat erosion/barrel life is important to competitive shooters, who fire thousands of rounds in practice and matches, vs. the medium/big game hunter. A cartridge that performs well ballistically with great accuracy, has long barrel life and low recoil is the competitive shooter’s ideal. For the hunter, other factors may weigh more heavily.

Cartridge Efficiency and Energy — Another Perspective
Former Lapua staffer Kevin Thomas explains that efficiency can be evaluated in terms of energy:

“Cartridge efficiency is pretty straight forward — energy in vs. energy out. Most modern single-based propellants run around 178-215 ft/lbs of energy per grain. These figures give the energy potential that you’re loading into the rifle. The resulting kinetic energy transferred to the bullet will give you the efficiency of the round. Most cases operate at around 20-25% efficiency. This is just another way to evaluate the potential of a given cartridge. There’s a big difference between this and simply looking at max velocities produced by various cartridges.”

Suppressor Facts — How to Get One and How They Work

suppressor silencer moderator facts fiction sound levels noise decibel dB
Map courtesy SilencerShop.com.

Q & A: TOP TEN Questions about Suppressors Answered HERE »

You’d like to protect your hearing, and maybe you’re a little curious about how your rifle might shoot suppressed. So you’re thinking of buying a suppressor (aka “can”, “moderator”, “silencer”). You can’t just get one off the shelf at Walmart. Acquiring a suppressor requires filling out paperwork and paying a Federal $200 Tax Stamp. Plus there is typically a pretty long wait. However, the good news is that suppressor ownership is now legal in 42 of the 50 American states — that’s 84%! For most American adults, getting a suppressor is legal, provided pass the required background checks.

States Where Suppressor Ownership is Allowed
Currently, the following 42 states allow private ownership of suppressors: AL, AK, AZ, AR, CO, CT, FL, GA, ID, IN, IA, KS, KY, LA, ME, MD, MI, MN, MS, MO, MT, NE, NV, NH, NM, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY.

Note: Even if you live in one of the states listed, you should still verify that owning a suppressor is legal in your area. Some states may have municipal- or county-based restrictions.

States Where Suppressor Ownership is Prohibited
Unfortunately, there are still eight (8) States that forbid private ownership of suppressors. The eight No-Go States are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island. In these eight states, private ownership of suppressors (aka “silencers”) is forbidden. Hopefully that a few of those eight hold-out states will change their laws in the months ahead.

Looking Inside a Suppressor in Action
Popular YouTube Channel Smarter Every Day recently released a cool video featuring rifle suppressors with see-through acrylic sleeves. The team filmed shots through the suppressors using ultra-high-speed (110,000 frame per second) cameras. When played back in super-slow-motion, you can see the flame propagate through the suppressor and the bullet move through each baffle before it exists the muzzle. Watch the results in the video below — it’s mesmerizing:

Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”

suppressor silencer moderator facts fiction sound levels noise decibel dB

Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.

Calculate True Elevation Changes with Burris Signature Rings

Burris signature rings inserts

Burris Signature Rings with polymer inserts are an excellent product. The inserts allow you to clamp your scope securely without ring marks. Moreover, using the matched offset inserts you can “pre-load” your scope to add additional elevation. This helps keep the scope centered in its elevation range while shooting at long range. Additionally, with a -20 insert set in the front and a +20 insert set in the rear, you may be able to zero at very long ranges without using an angled scope base — and that can save money. (To move your point of impact upwards, you lower the front of the scope relative to the bore axis, while raising the rear of the scope.)

Burris Signature Rings

Insert Elevation Values and Ring Spacing
People are sometimes confused when they employ the Burris inserts. The inset numbers (-10, +10, -20, +20 etc.) refer to hundredths of inch shim values, rather than to MOA. And you need the correct, matched top/bottom pair of inserts to give you the marked thousandth value. Importantly, the actual amount of elevation you get with Burris inserts will depend BOTH on the insert value AND the spacing between ring centers.

Forum member Gunamonth has explained this in our Shooters’ Forum:

Working with Burris Signature Rings
Burris inserts are [marked] in thousandths of an inch, not MOA. To know how many MOA you gain you also need to know the ring spacing. For example, with a -20 thou insert set in the front and a +20 thou insert set in the rear, if the ring spacing is 6″, the elevation change will be approximately +24 MOA upwards.

Here’s how we calculate that. If you have a 2 X 0.020″ “lift” over a distance of 6 inches (i.e. 0.040″ total offset at 0.5 feet) that’s equivalent to 0.080″ “lift” over 12 inches (one foot). There are 300 feet in 100 yards so we multiply 0.080″ X 300 and get 24″ for the total elevation increase at 100 yard. (Note: One inch at 100 yards isn’t exactly a MOA but it’s fairly close.)

Here’s a formula, with all units in inches:

Total Ring Offset
——————– X 3600 = Change @ 100 yards
Ring Spacing

(.020 + .020)
—————– X 3600 = 24 inches at 100 yards
Ring Spacing: 6 inches

NOTE: Using the above formula, the only time the marked insert offset will equal the actual MOA shift is when the center to center ring spacing is 3.60″. Of course, you are not required to use 3.60″ spacing, but if you have a different spacing your elevation “lift” will be more or less than the values on the inserts.

Benefits of Weakside Bolt Placement — For F-Class and Benchrest

left port McMillan Rifle

Most bolt-action rifle shooters work the bolt with their trigger-pulling hand. This is because most rifles sold to right-handed shooters come with right-side bolts, while “lefty” rifles come with left-side bolts. This “standard” configuration requires the shooter to take his dominant, trigger-pulling hand off the stock to cycle the bolt, then re-position his hand on the stock, and “re-claim” the trigger. Often the shooter must lift or move his head to work the bolt, and that also requires him to re-establish his cheek weld after each and every shot. Not good.

This really doesn’t make much sense for precision shooting with fore-end support*. There is a better way. If you leave your trigger hand in position and work the bolt (and feed rounds) with the opposite hand, then you don’t need to shift grip and head position with each shot. All this requires is a weakside-placed bolt, i.e. a left bolt for a right-handed shooter or a right bolt for a left-handed shooter. The video below shows a “Lefty” working a right bolt. Note how efficient this is:

As our friend Boyd Allen explains: “If you think about it, if you are going to work with a factory action where your options are left bolt and left port or right bolt and right port, and you are building a rifle that will only be shot from a rest, using the left/left for a RH shooter or using a right/right for a LH shooter works better than the conventional configuration”.

Shoot Like a Champ and Work the Bolt with Your Weakside Hand
Derek Rodgers is a recent F-TR World Champion, a King of 2 Miles champion, AND is the only person to have won BOTH the U.S. F-Open and the U.S. F-TR National Championships.

And guess what? Derek runs this kind of “opposite” bolt set-up. Yep, Derek shoots right-handed with a left bolt. Though Derek is a right-hander, he shoots with a Left Bolt/Left Port (LBLP) action. He pulls the trigger with his right index finger, while working the left-side bolt with his left (weakside) hand. This allows him to stay in position, and maintain his cheekweld. He places his right hand on the grip, while manipulating the bolt (and feeding rounds) with his non-trigger-pulling hand.

*For true standing, off-hand shooting (whether in competition or on a hunt), a conventional strongside bolt placement makes sense, since the non-dominant arm must support the front of the rifle all the time. When shooting from bipod or rest, it’s a different story.

Shooting at Indoor Ranges — Proper Range Procedures

Safety Video NSSF Indoor Range Etiquette

August is National Shooting Sports Month. Many indoor ranges are offering promotional specials this month. Range sessions may be reduced in price (or free) and you’ll find discounts on guns, ammo, and accessories. Shooting indoors is fun, and at many indoor ranges you can shoot in the evening after work. But when shooting indoors you should always be extra careful. Follow all key gun safety practices and adhere to proper range “Etiquette”. We also recommend double hearing protection — plugs under muffs.

The NSSF (NSSF) offers a useful Range Safety and Etiquette video. This 8.5-minute video explains safe practices, especially at indoor ranges. In the video, the moderator list the basic rules of gun safety, before covering key range etiquette topics such as range officer commands, how to uncase your firearm on the range when you first arrive, and what to do if a firearm is accidentally dropped. There are also safety tips specific to handling both semi-automatic handguns and revolvers.

Safety Video NSSF Indoor Range Etiquette

BAD RANGE BEHAVIOR — Five Things NOT to Do at the Range

Here are the five worst behaviors we’ve seen at indoor ranges. These behaviors are both dangerous and inconsiderate. Any one of these behaviors can get you permanently banned from an indoor range.

1. Sweeping other individuals after loading a weapon behind the firing line is very bad. All your weapons should be empty until you reach your shooting station.

2. Turning the handgun sideways while trying to clear a malfunction or insert/remove a magazine. This will point the muzzle at a fellow shooter. Or, after shooting a gun, the shooter fails to clear the weapon and then places the gun somewhere near the shooting station with the muzzle in an unsafe position.

3. Reacting unpredictably when firing a high recoil handgun. We’ve seen people take a second shot by accident with the muzzle way off target.

4. Not obeying range commands — in particular continuing to shoot during called cease-fires.

5. Poorly aimed shooting that hits target frames or carriers, causing ricochets.

Seven Types of People at the Gun Range — HUMOR

This video is satire, but with lots of truth in the characterizations. Laughter guaranteed.

Double-Up on Hearing Protection When Shooting Indoors

Howard Leight Impact Pro Electronic Muffs NRR 30

When shooting rifles and pistols indoors we recommend quality muffs with earplugs underneath, offering double protection. When inside an enclosed range, with other shooters blasting away right next to you, you really need effective hearing protection. But you also need to hear range commands and be able to communicate with your fellow shooters. That’s why we recommend electronic muffs with plugs underneath.

Volquartsen 17 HMR Dustin Ellermann 17 HMR

We know our many of our readers enjoy Prairie Dog varminting safaris. For long P-Dog shots you’ll definitely want a centerfire. We like the 20 Practical in an AR and a 22 BR/BRA in a bolt-action. That will have you covered out to 700 yards. But for shorter shots on small critters — say inside 150 yards — it makes sense to have an accurate 17 HMR rimfire rig. Today’s 17 HMRs are capable of surprising accuracy, rivaling a good centerfire rig, but with way less recoil and much lower cost per shot. And the 17 HMR offers more than double the velocity of a .22 LR — up to 2650 fps with a 17-grain bullet.

Top Shot former Champion Dustin Ellerman likes his Volquartsens, and we can see why. With one of his favorite 17 HMR rimfire varmint rigs, he’s seen some outstanding accuracy with CCI ammo. A few seasons back, on his Facebook page, Dustin reported: “Prepping for prairie dogs and I’m floored by this cold, sub-half-inch group shot with the Volquartsen Custom 17 HMR at 100 yards.” This thumbhole-stock rifle features a Bowers Group USS suppressor, and 3-12x56mm Meopta Scope. Dustin tried different types of CCI 17 HMR ammo. This small group was shot with CCI A17 ammo.

What’s the effective range of a 17 HMR on prairie dogs? You might be surprised. in 2015, Dustin took another Volquartsen 17 HMR on a Prairie Dog hunt in Wyoming. He was impressed with the rifle (shown below) and the little rimfire cartridge. Dustin says the effective range of the 17 HMR is farther than one might expect: “I made hits out to 300 yards. 200 yards was easy as long as the wind wasn’t too bad.”

Here’s the Volquartsen 17 HMR Dustin used in Wyoming in 2015:

After that 2015 P-Dog expedition, Dustin became a fan of the 17 HMR cartridge: “Never paid it much attention before now because the ammo is five times more expensive than .22 LR and I mostly target shoot. However, for prairie dogs, the 17 HMR is amazing!” Consider this — Hornady’s 17 HMR ammo pushes a 17gr V-Max bullet at 2550 fps, twice as fast as typical .22 LR rounds.
