6.5 Creedmoor vs. Other Mid-Sized .264-Caliber Cartridges

6.5 Creedmoor Rifleshooter.com velocity barrel cut cut-down test saw blade

6.5 Creedmoor vs. Other Mid-Sized 6.5mm Cartridges
The 6.5 Creedmoor is a very popular cartridge with the tactical and PRS crowd. This mid-size cartridge offers good ballistics, with less recoil than a .308 Winchester. There’s an excellent selection of 6.5mm bullets, and many good powder choices for this cartridge. When compared to the very accurate 6.5×47 Lapua cartridge, the 6.5 Creedmoor offers similar performance with less expensive brass options. For a tactical shooter who must sometimes leave brass on the ground, brass cost is a factor to consider. Here’s a selection of various 6.5mm mid-sized cartridges. Left to right are: 6.5 Grendel, 6.5×47 Lapua, 6.5 Creedmoor with 120gr A-Max, 6.5 Creedmoor with 142gr Sierra MK, and .260 Remington.

When asked to compare the 6.5 Creedmoor to the 6.5×47 Lapua, Rifleshooter.com’s Editor stated: “If you don’t hand load, or are new to precision rifle shooting, get a 6.5 Creedmoor. If you shoot a lot, reload, have more disposable income, and like more esoteric cartridges, get a 6.5×47 Lapua. I am a big fan of the 6.5×47 Lapua. In my personal experience, the 6.5×47 Lapua seems to be slightly more accurate than the 6.5 Creedmoor. I attribute this to the quality of Lapua brass.” But now that Lapua is producing top-quality 6.5 Creedmoor brass with small primer pockets, we could have a “second generation” 6.5 Creedmoor that rivals ANY mid-sized cartridge for efficiency AND accuracy. We will soon know how well the 6.5 Creedmoor cartridge performs with Lapua brass.

The first shipment of Lapua 6.5 Creedmoor brass has arrived in the USA. It features a small flash hole and small primer pocket. We have some for testing…

New Lapua 6.5 Creedmoor Brass Field Tests Soon
Our friends at 65Guys.com will be testing the new Lapua 6.5 Creedmoor brass next week. The goal will be to determine if Lapua’s new Small Primer Pocket/Small Flash Hole brass allows higher velocities than American-made brass (Hornady specifically). In addition the 6.5 Guys want to see how well the new Lapua brass holds up after dozen (or more) firing cycles. They’ll hammer the new brass pretty hard to see how it fares with repeated stout loads. Stay tuned…

Hornady Match Ammo Reviewed by Brownells

Hornady 6.5 Creedmoor Ammo
Photo courtesy AmmoSquared.com sales.

Each week, Brownells releases a new product video. This week’s review spotlights Hornady match bullets and factory ammo of interest to PRS and tactical shooters. Hornady’s ELD Match ammunition is now offered in the popular 6.5 Creedmoor and 6mm Creedmoor chamberings, along with .223 Rem, 6.5 Grendel, 260 Rem, .308 Win, .30-06, .300 Win Mag, and .338 Lapua Mag. This ammo is loaded with Hornady’s ELD Match bullets which feature heat-resistant tips. The ELD bullet line offers impressive BCs at prices that are quite a bit more affordable than some other match bullets. For example, a 100-ct box of 130gr 6.5mm ELD Match bullets is $32.46 at Midsouth.

For 6.5 Creedmoor shooters, three bullet weights will be offered in factory-loaded 6.5 Creedmoor ELD Match ammo: 120 grain (SKU: 81491), 140 grain (SKU: 81500), and 147 grain (SKU: 81501). Hornady’s 6mm Creedmoor ELD Match ammo is offered in one weight, 108 grain (SKU: 81391).

The 6.5 Creedmoor and 6mm Creedmoor chamberings are very popular with PRS competitors. These cartridge types offer excellent accuracy, and a good ballistics with moderate recoil. Many factory rifles, such as the impressive new Tikka T3X A1, are offered in the 6.5mm chambering.

This video also features Hornady’s new Black Ammunition designed for gas guns. Offerings include 5.45x39mm, 6.5 Grendel, 6.8 SPC, 300 AAC BLK, 450 Bushmaster, and .308 Win. The 6.5 Grendel ammo attracted our attention. That chambering is inherently accurate and could be used successfully in an XTC match rifle or in the new PRS Gas Gun Series.

Lapua 6.5 Creedmoor Brass Has Arrived at Graf & Sons

Lapua 6.5 Creedmoor cartridge brass

The most hotly-anticipated cartridge brass, the new-for-2017 6.5 Creedmoor cases from Lapua, arrived late last week at Graf & Sons. With the strength and uniformity for which Lapua brass is famous, this new brass should definitely “raise the bar” for 6.5 Creedmoor and 6mm Creedmoor shooters. Note — the new Lapua 6.5 Creedmoor brass features a small flash hole and small primer pocket. As of 9:00 am Monday morning this brass is in stock at Grafs.com priced at $119.99 per 100-ct box, with a max order of five (5) boxes.

UPDATE: The 6.5 Creedmoor brass sold out after we posted this story. But there will be more coming. You can ask Graf’s to be notified as soon as the next shipment arrives.

Lapua 6.5 Creedmoor cartridge brass

TECH TIP: For those who have been loading Hornady or other-brand 6.5 Creedmoor brass with large primer pockets and large flash holes, you may need to reconfigure your reloading tools. Check your sizing die — you may need to change to a smaller-diameter decapping rod. In addition you’ll need to use a small primer size “pusher” on your priming tool.

6.5 Creedmoor Load Data from Sierra Bullets

Sierra Load Data 6.5 Creedmoor

Sierra Bullets has just released very complete load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly.

Sierra Load Data 6.5 CreedmoorDeveloped in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber). Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Varget, Win 760, and RE-17. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power, precision rifle series and benchrest competitions. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success which should insure its legacy for decades to come.

Savage Turns to the Dark Side — Introduces AR-Type Rifles

Savage AR15 AR10 AR-10 Black rifle AR MSR Modern Sporting Rifle

Savage Arms has joined the black rifle bandwagon with its new MSR Series of gas guns. Savage will offer four AR-style semi-automatic rifles in 2017. Savage will offer a variety of buttstock configurations, barrel lengths, along with some interesting chambering options. The MSR 15 Patrol and Recon feature a .223 Wylde target chamber for use with 223 Rem. or 5.56x45mm. The MSR 10 Hunter and MSR 10 Long Range models are AR-10 platform rigs offered in 6.5 Creedmoor and .308 Win chamberings. The top-of-the-line MSR 10 Long Range model carries a hefty $2284 MSRP price-tag, but it does include a two-stage AR Blaze target trigger, adjustable gas block, and a genuine Magpul® PRS Gen3 buttstock.

While most of the engineering of the MSR series is classic AR, there are some interesting features and notable upgrades. The MSR 10 Long Range offers a non-reciprocating, left-side charging handle (along with conventional rear charging handle). All the MSR rifles have high-quality barrels with a durable surface hardening treatment known as Melonite QPQ. This should make the rifles run longer (with higher round count) before needing replacement barrels. Bill Dermody of Savage states: “These are high-performance barrels you’d have to buy as an upgrade with standard AR-15s.”

Savage MSR Notable Features:
Non-reciprocating SIDE charging handle on MSR 10 LR (plus normal charging handle)
1:8″-twist Barrels, Melonite QPQ hardening, 5R rifling (MSR 15 Patrol and Recon)
1:8″ or 1:10″-twist Barrels, Melonite QPQ hardening, 5R rifling (MSR 10 Hunter and LR)
Conventional AR-Type Gas System (No Op Rod)
Adjustable Gas Block (MSR 10 Hunter and LR)
Modular-Style Fore-end/Handguard
Flip-up Front and Rear Sights

Field Test of Savage MSR 15 Patrol
YouTube ace .22 Plinkster got his hands on one of the very first Savage MSR 15 Patrol M4 models. In this video, he tests it for function and accuracy, finding the MSR 15 to be “a good shooter”. He adds: “The Patrol is Savage’s entry-level M4. Because this rifle is brand new … you may want to check out Savage’s website at www.SavageArms.com.”

Savage AR15 AR10 AR-10 Black rifle AR MSR Modern Sporting Rifle

This Twang ‘N Bang video explains the key features of the MSR 10 Long Range, including the side charging handle and QPQ-treated barrel. It also describes the specs of the other three models.

Savage’s new MSR 10 Hunter and MSR 10 Long Range are purpose-built modern sporting rifles for game hunting and long-range shooting. Both are available in .308 Winchester and 6.5 Creedmoor chamberings. Both models are built on compact, lightweight frames and feature adjustable gas blocks, plus the MSR 10 Long Range is equipped with a non-reciprocating, side-charging handle (see below).

Savage AR15 AR10 AR-10 Black rifle AR MSR Modern Sporting Rifle

On the AR-15 platform, the new MSR 15 Patrol and MSR 15 Recon are chambered in .223 Wylde for safe, reliable function with both 223 Rem. and 5.56x45mm ammo. All Savage MSRs offer premium features such as 5R button-rifled barrels with Melonite QPQ surface hardening, new BLACKHAWK! furniture, upgraded sights and more.

6.5 Creedmoor — Velocity and Barrel Length — What to Expect

Rifleshooter.com 6.5 Creedmoor cut-down test

What do you get when you cut a 6.5 Creedmoor-chambered barrel down to just over 16 inches? A lot more velocity than you might think. Our friends at Rifleshooter.com recently did a barrel cut-down test with 6.5 Creedmoor test rifle, shortening the barrel from 27 to 16.1 inches in one-inch increments. Surprisingly, with a 142gr Sierra MK, the total velocity loss (as measured with a Magnetospeed) was just 158 FPS, an average of 14.4 FPS per inch of barrel length. With the lighter 120gr A-Max bullet, the total velocity loss was 233 FPS, or 21.8 FPS average loss per inch of barrel.

CLICK HERE to SEE All Velocity Values at All Barrel Lengths

To perform this velocity test, our friend Bill, Rifleshooter.com’s editor, built up a 6.5 Creedmoor rifle using a Remington Model 7 action, 1:8″ twist Green Mountain CM barrel, and MDT LSS Chassis, all obtained from Brownells.com.

Test Procedure
Five (5) rounds of each type of cartridge were fired at each barrel length and the velocity data was recorded with a MagnetoSpeed V3 barrel-mounted chronograph. The rifle was then cleared and the barrel was cut back one inch at a time from 27″ to just over 16″. NOTE: During this winter test, the air temperature was a very chilly 23° F. One would expect higher velocities across the board had the outside temperature been higher.

Read Full Story with All Test Results at Rifleshooter.com

The photo below shows how the barrel was cut down, inch-by-inch, using a rotary saw. The barrel was pre-scored at inch intervals. As the main purpose of the test was to measure velocity (not accuracy) the testers did not attempt to create perfect crowns.

Lapua Now Offers 6.5 Creedmoor Cartridge Brass

Lapua Creedmoor 6.5 Brass cartridge 1.5mm tactical case

Here’s great news for mid-size cartridge fans, and especially PRS and tactical shooters. Lapua just announced it will produce 6.5 Creedmoor cartridge brass, which should be available in the first quarter of 2017. This premium-quality brass features a small primer, and 1.5mm flash hole (as found on Lapua’s 6mmBR, 6.5×47 Lapua, and 220 Russian brass). We expect Lapua’s 6.5 Creedmoor brass will set new standards for accuracy and case life for this popular mid-sized cartridge. Of course Lapua’s new 6.5 Creedmoor brass can also be necked down and loaded in 6mm Creedmoor configuration. With the small primer pocket and proven strength of Lapua brass, we think 6.5 Creedmoor shooters will see enhanced cartridge velocities with the ability to maintain tight primer pockets even with very stout loads. And we expect accuracy to be on a par with Lapua’s excellent 6.5×47 Lapua brass. Taken together, this is an exciting product release. Here is Lapua’s official announcement:

Lapua Creedmoor 6.5 Brass cartridge 1.5mm tactical case

We are happy to announce the addition of the 6.5 Creedmoor case to the Lapua line! Despite a relatively short time on the marketplace, the 6.5 Creedmoor has made a tremendous splash in the field, rapidly becoming one of the most requested cases we hear about from shooters. Lapua’s 6.5 Creedmoor is designed to function in a short action, which is also a plus for hunters, vitally concerned with the rifle’s weight and compactness. In fact, many of the same features which make for a successful competition cartridge, translate nicely to the hunting fields as well.

For most species of mid-size game such as deer or boar, the Creedmoor will prove to be a deadly performer. And while the selection of high grade Match bullets in the 6.5 bore size is tremendous, there’s no shortage of exceptionally good hunting bullets either. The 6.5s as a group have always been known as excellent performers on game.

Lapua Creedmoor 6.5 Brass cartridge 1.5mm tactical caseMade with Lapua’s typical dedication to precision, our new 6.5 Creedmoor case has been refined just a bit, to make it an even better performer. We’ve opted for the small rifle primer, which normally produces an optimized ignition and better accuracy than large primers in mid-sized cartridges like the Creedmoor.

We’ve also incorporated our smaller-diameter flash hole (1.5mm, rather than the industry-standard 2.0mm), which has proven to provide enhanced accuracy, and is used in a number of our other accuracy-oriented cases. In this respect, the new 6.5 Creedmoor joins the ranks of our other dedicated accuracy cartridges such as the .220 Russian (6mm PPC), the 6mmBR Norma, the 6.5×47 Lapua, and the .308 Win Palma cases.

And naturally, the new 6.5 Creedmoor will be made with our well-known Passion for Precision. Strictest control over the metallurgy, the forming and drawing processes, precise annealing all performed under the watchful eyes of our production experts. For you, the handloader, that means the durability for which our cases are famous, combined with consistency and long life. Already proven in competition, we predict that the 6.5 Creedmoor will be a force to be reckoned with for many years to come.

Comment on Lapua’s new 6.5mm Creedmoor
Our British friend Laurie Holland was excited about the new 6.5 Creedmoor brass from Lapua: “With this and Peterson Cartridge on the bandwagon, plus another U.S. brass maker… the Creedmoor’s momentum is becoming impressive.” Laurie observes: “A small primer Lapua-cased 6.5mm Creedmoor is in effect a 6.5X47 Lapua ‘Improved’!” That’s a pretty interesting concept indeed. Which makes us wonder if the .260 Remington has finally been fully eclipsed. With Lapua 6.5 Creedmoor brass you can probably get very, very close to .260 Rem performance in a much more efficient case.

New Temp-Stable Alliant Reloder 16 Now Available

Reloder Reloader 16 Alliant Powder Propellant Bofors TZ temperature stability temp stable H4350

Here’s an important announcement for anyone who uses a powder in the 4350 range. Alliant is now shipping the all-new Reloder 16 powder. The burn rate is slightly faster than Reloder 17, and a bit slower than Varget or Reloder 15. Notably, this new Reloder 16 powder is very temp stable. AccurateShooter.com was shown “top secret” test results comparing Reloder 16 with other popular propellants, including Hodgdon Extreme series powders. The results for Reloder 16 were remarkable. Reloder 16 showed extremely constant velocities even with very high ambient temps — so this is a powder you can shoot even on hot Arizona summer days.

CLICK HERE for Reloder 16 Suggested Load Recipes

This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures.

Reloder Reloader 16 Alliant Powder Propellant Bofors TZ temperature stability temp stable H4350

As a result, Reloder 16 offers outstanding temperature stability. Based on the test results we’ve seen, if you are using H4350 or IMR 4451 currently, you should definitely give Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.

Reloder Reloader 16 Alliant Powder Propellant Bofors TZ temperature stability temp stable H4350

Match and Hunting Cartridge Applications:
Alliant tells us that Reloader 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder may work very well in these popular match cartridges: 6XC, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Load Data Sheet shows a 2772 FPS load with 142gr SMKs in the .260 Rem.

New Howa Tactical Rig — Howa Chassis Rifle (HCR)

Howa HCR Chassis Rifle PRS Tactical Aluminum stock HACT Trigger

Here’s an item for tactical and Precision Rifle Series (PRS) shooters. Howa is releasing a new rifle with a modular metal chassis. The new Howa HCR (Howa Chassis Rifle) combines a Howa 1500 barreled action with a modern, fully-adjustable aluminum chassis. The Howa’s MSRP is $1299.00, so the HCR is directly competitive with the Ruger Precision Rifle (RPR). Available chamberings are: .223 Remington, .243 Winchester, 6.5 Creedmoor, and .308 Winchester.

Howa HCR Chassis Rifle PRS Tactical Aluminum stock HACT Trigger

Mounted on an AR-style buffer tube system, the Howa HCR utilizes the fully adjustable LUTH-AR MBA-3 stock. Length of Pull is adjustable form 12.5″ to 16.75″. Comb height is also adjustable to fine tune for scope height-over-bore. Weight with a 24″ barrel is 10.2 pounds (before optics), so this Howa HCR is lighter that some similar rifles on the market.

Howa HCR Chassis Rifle PRS Tactical Aluminum stock HACT Trigger

Howa HCR Features

• Howa 1500 Barreled Action with 20″ and 24″ Heavy Barrel options
• Black 6061-T6 Aluminum Chassis with Free-Float M-LOK Forend
• LUTH AR Buttstock with LOP Adjustment (12.5″ to 16.75″) and Adjustable Comb
• 10-RD ACCURATE Detachable, Teflon-coated Steel Magazine
• Two-Stage H.A.C.T. Trigger
• 3 Position Safety

Howa HCR Chassis Rifle PRS Tactical Aluminum stock HACT TriggerThe HOWA HCR features an adjustable, two-stage HACT trigger, set for about 3 pounds (combined stages). Crisp and repeatable, this is an excellent trigger for a factory gun. In our opinion, the HACT trigger is clearly superior to the trigger on the Ruger RPR, as well as the Savage AccuTrigger. And there is no annoying Glock-style safety lever in the middle of the trigger blade.

Available in .223 Rem, .243 Win, 6.5 Creedmoor and .308 Win chamberings.

NOTE: For all chamberings, 24″ barrels are offered, with 20″ options for the .223 Rem and .308 Win as well. Twist rates are 1:9″ for .223 Rem, 1:10″ for .243 Win, 1:8″ for 6.5 Creedmoor, and 1:10″ for .308 Win. We think .243 Win shooters will NOT be happy with the 1:10″ twist. We would prefer to see a 1:8″-twist for the .243 Win so it can shoot the 105-115 grain 6mm bullets. Most competitive 6mm shooters will want a true 8-twist or even a 1:7.5″.

DIY Hunting Rifle Upgrade — 6.5 Creedmoor Ruger American Rifle

Ruger American Rifle Predator 6.5 Creedmoor Boyds Stock inletting bedding

The NRA’s American Rifleman showcased an interesting project this week — an upgraded Ruger American Rifle Predator in 6.5 Creedmoor. The video below shows how a laminated wood stock from Boyd’s Gunstocks was adapted for the Ruger. A Boyds Prairie Hunter model in gray laminate was selected. This was custom-bedded to the Ruger’s action using Brownell’s Acraglas.

Ruger American Rifle Predator 6.5 Creedmoor Boyds Stock inletting beddingAll Ruger American Rifle models employ dual aluminum V-Blocks to support the action. These fit slots in the underside of the action. Boyds makes its own version of these V-Blocks which were installed in the Boyds stock to secure the action.

Project leader Joe Kurtenbach says the size, shape, and geometry of the Boyds V-Blocks is very accurate, so they fit the Ruger action well. To further support the action, Acraglas bedding compound was applied to the inside of the stock, after release compound was applied to the barreled action. With this DIY bedding job, the Boyds laminated stock is definitely an improvement over this original “Tupperware” factory stock.

DIY Bargain Hunter Upgrade
American Rifleman states: “The Ruger American has some great features—hammer-forged barrel, reliable action, crisp trigger — but many would not consider the molded, polymer stock to be among them. Luckily, there are aftermarket options to enhance the rifle’s utility and aesthetics. A durable, attractive stock from Boyds Gunstocks and some DIY action bedding, using Brownells Acraglas, is the next step in the precision-driven hunting rifle build.”

Choice of Gun and 6.5 Creedmoor Chambering
For this project, American Rifleman’s Joe Kurtenbach selected one of his favorite cartridges, the 6.5 Creedmoor. Introduced in 2007 by Hornady, the accurate, flat-shooting 6.5 Creedmoor has proven very popular with both hunters and tactical/PRS shooters. The Ruger American Rifle Predator was chosen for its affordable price, reliable action, and Ruger Marksman adjustable trigger.

In this video, Kurtenback explains how and why the 6.5 Creedmoor chambering and Ruger American Rifle were chosen for the Precision Hunter rifle build project.

Masterpiece arms MPA Production Rifle PRS MPA PCR Savage BA Lite

The Precision Rifle Series (PRS) has introduced a new, price-capped Production Class in an effort to boost participation by making competition more affordable. Under recently-issued PRS rules, Production Class rifles may cost no more than $2000.00. The rules state:

“Production Division combined rifle and scope MSRP as listed on the company’s website shall not exceed $3,000 USD, the rifle shall not exceed $2,000 USD and the optic not exceed $2,000 USD.

Production Division rifles are not permitted to be altered or improved in any way from the original factory configuration.

In an effort to prevent exorbitant costs for beginning shooters, Production Division round count will not exceed 80 rounds.”

Masterpiece arms MPA Production Rifle PRS MPA PCR Savage BA Lite

To fit the new Production Class Rules, MasterPiece Arms (MPA) has developed the new BA Lite PCR Competition Rifle built around a Savage Model 12 short action. Designed specifically for the new PRS Production Class, MPA’s PCR Competition Rifle offers many premium features yet stays under the $2,000 Class limit. The Savage action is upgraded with a Rifle Basix 2-lb trigger, and the adjustable, modular chassis offers a bag rider, barricade stop, and even a built-in bubble level. Bipods can be attached up front to a rail, with optional spigot mount. MPA PCR Rifles come with stainless Bergara barrels, 22-26 inches in length, fitted with MPA muzzle brakes (muzzle thread is 5/8-24 TPI).

The barrel twist is caliber-specific and the barrel muzzle thread is 5/8-24 TPI.

Editor’s Note: While the MPA PCR Competition rifle has nice features, it’s hard not to compare it to the Ruger Precision Rifle costing hundreds less. The latest Gen 2 Ruger Precision Rifle, with a sleeker handguard and factory muzzle brake, is available for under $1500.00 “street price”. Ruger lists a $1599.00 MSRP for the Gen 2 RPR versus $1399.00 for Gen 1 models.

6.5 Creedmoor 1500 yards applied ballistics kestrelIt’s not easy to place a first shot on target at 1500 yards. You must measure the wind speed with precision, know your exact muzzle velocity, and have a sophisticated ballistics solver. In this short video from Ryansrangereport.com, the shooter manages a first-round hit on a steel silhouette at 1500 yards. He used a Kestrel 4500 NV Weather Meter with Applied Ballistics software to figure out the trajectory for his 6.5 Creemoor rounds.

The Kestrel recorded a wind velocity, and the internal software calculated a solution of 17 Mils elevation (that’s 928 inches of drop) with 2.5 Mils windage. “Bang” — the shooter sends it, and 2.6 seconds later “Clang” he had a hit (flight time was 2.6 seconds). Bryan Litz observes: “This is the science of accuracy (in the form of an Applied Ballistics Kestrel) being put to good use at 1500 yards”.

Later in the video (1:05-1:15) the shooter places three rounds on steel at 1000 yards in just 10 seconds. The three shots all fall within 10″ or so — pretty impressive for rapid fire. The shooter reports: “[In my 6.5 Creedmoor] I’m using a 136gr Lapua Scenar L. This bullet has impressed me. It screams out of my barrel at 2940 fps and holds on all the way out to 1,500 yards.”

The rifle was built by Aaron Roberts of Roberts Precision Rifles (RPRifles.com). Chambered for the 6.5 Creedmoor, it features a Leupold Mark VI 3-18x44mm scope.

Ruger Upgrades Ruger Precision Rifle and Raises Price $200.00

Ruger Precision Rifle New Model Enhanced handguard muzzle brake

The Ruger Precision Rifle (RPR) has been a huge sales success. Nearly a year after its introduction, the RPR remains in very high demand. The first production run by Ruger essentially sold out, so it is very hard to find one for sale, in any caliber.

CLICK HERE for Large-format Ruger Precision Rifle Product Brochure (4mb PDF).

Though it has a big winner on its hands, Ruger has made some upgrades to its popular RPR. An “enhanced” RPR will be offered with a new handguard, bolt shroud, and muzzle brake. Two new models have been added to the RPR line-up, the model 18004 in .308 Win, and the model 18008 in 6.5 Creedmoor. These models, priced at $1599.00 MSRP, feature a new, low-profile handguard, a new aluminum bolt shroud, and a muzzle brake. The new handguard will work better for scopes with large front objectives. The muzzle brake should reduce felt recoil, but we do wonder whether accuracy might suffer. The brakeless, first-generation RPRs exhibited very good accuracy most of the time.

Ruger Precision Rifle New Model Enhanced handguard muzzle brake

For the time being, the original model RPRs will be offered along with the new enhanced RPRs: “Both the original and enhanced configurations will be available from Ruger for a time, with the initial pattern being phased out as supplies are depleted.” (Source: American Rifleman). But there is a catch. The new models cost $200.00 more than Gen 1 RPRs. Ruger lists a $1599.00 MSRP for the enhanced RPRs versus $1399.00 for Gen 1 models.

To See NEW FEATURES, click the image below, then SCROLL down the page on the Ruger web page that loads. Yes, the VIDEO is there — you just have to scroll down.

According to American Rifleman, the new handguard has multiple benefits: “Still free-floating and KeyMod-compatible, the new design omits the original’s top-mounted Picatinny rail in order to increase scope clearance. Given the larger objective lenses utilized by long-range optics, this enhancement makes a lot of sense. The bottom surface of the new handguard is also contoured with a flatter surface, providing for a more stable foundation for the mounting of bipods than the original model.” Current RPR owners can purchase the new-style 15″ aluminum handguard for $249.95 from ShopRuger.com.

The original, Gen 1 Ruger Precision Rifle had a threaded muzzle covered by a thread cap. The new “enhanced model” features a factory-installed “hybrid” brake fitted to the barrel. This brake combines radial holes in the rear half with large, angled side ports in the front. Ruger claims the brake reduces recoil almost 40% on a 6.5 Creedmoor. This brake can be purchased separately for $99.95 from ShopRuger.com.

Six-Five Smackdown: The .260 Remington vs. 6.5×55 Swedish

6.5x55 SE, 6.5 Swedish 6.6x55mm .260 Rem Remington Laurie Holland comparison

The .260 Remington and the 6.5×55 Swedish (aka 6,5x55mm SE) are both very popular cartridges with hunters and target shooters. The 6.5×55 has a long military heritage and a great record as a hunting round. The .260 Rem, essentially a .308 Win necked down to .264 caliber, is a more recent cartridge, but it grows in popularity every year, being one of the top cartridges for tactical/practical competitions. It offers better ballistics and less recoil than the parent .308 Win cartridge. In our Shooter’s Forum, respected UK gun writer Laurie Holland provided a good summary of the differences between the two chamberings. Laurie writes:

Remington 260 CartridgeThe 6.5×55 case has 6 or 7% more capacity than the .260s, even more in practice when both are loaded to standard COALs with heavy bullets, which sees them having to seated very deep in the .260 Rem using up quite a lot of powder capacity. So loaded up for reasonable pressures in modern actions, the 6.5×55 will give a bit more performance.

The issue for many is what action length is available or wanted, the 6.5×55 requiring a long action. So sniper rifle / tactical rifle competitors will go for the .260 Rem with the option of the many good short-bolt-throw designs around with detachable box magazines (DBMs). If a bit more performance is needed, the .260 AI (photo right) can yield another 100-150 fps velocity, depending on bullet weight.

6.5 Creedmoor — Barrel Cut-Down Velocity Tests

Rifleshooter.com 6.5 Creedmoor cut-down test

What do you get when you cut a 6.5 Creedmoor-chambered barrel down to just over 16 inches? A lot more velocity than you might think. Our friends at Rifleshooter.com recently did a barrel cut-down test with 6.5 Creedmoor test rifle, shortening the barrel from 27 to 16.1 inches in one-inch increments. Surprisingly, with a 142gr Sierra MK, the total velocity loss (as measured with a Magnetospeed) was just 158 FPS, an average of 14.4 FPS per inch of barrel length. With the lighter 120gr A-Max bullet, the total velocity loss was 233 FPS, or 21.8 FPS average loss per inch of barrel.

CLICK HERE to SEE All Velocity Values at All Barrel Lengths

To perform this velocity test, our friend Bill, Rifleshooter.com’s editor, built up a 6.5 Creedmoor rifle using a Remington Model 7 action, 1:8″ twist Green Mountain CM barrel, and MDT LSS Chassis, all obtained from Brownells.com.

Test Procedure
Five (5) rounds of each type of cartridge were fired at each barrel length and the velocity data was recorded with a MagnetoSpeed V3 barrel-mounted chronograph. The rifle was then cleared and the barrel was cut back one inch at a time from 27″ to just over 16″. NOTE: During this winter test, the air temperature was a very chilly 23° F. One would expect higher velocities across the board had the outside temperature been higher.

The photo below shows how the barrel was cut down, inch-by-inch, using a rotary saw. The barrel was pre-scored at inch intervals. As the main purpose of the test was to measure velocity (not accuracy) the testers did not attempt to create perfect crowns.

6.5 Creedmoor vs. Other Mid-Sized 6.5mm Cartridges
The 6.5 Creedmoor is a very popular cartridge with the tactical and PRS crowd. This mid-size cartridge offers good ballistics, with less recoil than a .308 Winchester. There’s an excellent selection of 6.5mm bullets, and many powder choices for this cartridge. When compared to the very accurate 6.5×47 Lapua cartridge, the 6.5 Creedmoor offers similar performance with less expensive brass. For a tactical shooter who must sometimes leave brass on the ground, brass cost is a factor to consider. Here’s a selection of various 6.5 mm mid-sized cartridges. Left to right are: 6.5 Grendel, 6.5×47 Lapua, 6.5 Creedmoor with 120gr A-Max, 6.5 Creedmoor with 142gr Sierra MK, and .260 Remington.

When asked to compare the 6.5 Creedmoor to the 6.5×47 Lapua, Rifleshooter.com’s editor stated: “If you don’t hand load, or are new to precision rifle shooting, get a 6.5 Creedmoor. If you shoot a lot, reload, have more disposable income, and like more esoteric cartridges, get a 6.5×47 Lapua. I am a big fan of the 6.5×47 Lapua. In my personal experience, the 6.5×47 Lapua seems to be slightly more accurate than the 6.5 Creedmoor. I attribute this to the quality of Lapua brass.”

The 6.5 Creedmoor — Profile of Popular Mid-Sized Cartridge

6.5 Creedmoor

We often get questions about the 6.5 Creedmoor Cartridge — folks ask where they can find good resources for this cartridge, which is popular with Across-The-Course, High Power, and tactical shooters. We did some searching and found that the August 2011 digital edition of Shooting Sports USA has a good article for all fans of the 6.5 Creedmoor.

6.5 Creedmoor Development of the 6.5 Creedmoor Cartridge
In the August 2011 Edition of Shooting Sports USA you’ll find a lengthy feature on the 6.5 Creedmoor cartridge. This story covers the origin of the cartridge and its performance both as a match cartridge and as a hunting round. Hornady Chief Ballistician Dave Emary explained: “the original intent of the cartridge was as an across-the-course match cartridge. We envisioned it as an off-the-shelf round that would produced the accuracy and ballistics to compete in all match disciplines right out of the box. At the same time we realized that the same characteristics would make an exceptional hunting cartridge with the right bullets.”

6.5 Creedmoor Annealing6.5 Creedmoor Brass No Longer Washed After Annealing
Here’s an interesting update on Hornady 6.5 Creedmoor brass and loaded ammo. In a move to improve case quality and neck uniformity, Hornady recently changed the 6.5 Creedmoor production process, eliminating the case-washing step after annealing. So now you will see annealing coloration on 6.5 Creedmoor brass, just like on Lapua brass. Dennis DeMille of Creedmoor Sports wanted to improve the consistency/uniformity of 6.5 Creedmoor case-necks. At Dennis’ suggestion, Hornady conducted tests which showed that the “standard industry practice” of washing brass could potentially alter the necks in undesirable ways. Bottom line, unwashed annealed brass was determined to have an accuracy edge over washed brass. Looking at these results, Hornady decided to forgo the post-anneal washing process. As a result, the latest 6.5 Creedmoor brass now displays the distinctive coloration left by neck/shoulder annealing. Learn something new every day, eh?

Tactical Transformer: .243 Win Becomes a 6-6.5×47 Lapua

6mm-6.5x47 6x47 Lapua Tactical Accuracy International

Article by Bill, Editor of Rifleshooter.com
A few years ago I built a custom switch-barrel Remington 700 on an AICS Chassis chambered in .243 Winchester and .308 Winchester. I found the .243 Win finicky during load development and started looking at other options for the 6mm Bartlein 1:8″-twist HV barrel.

6mm-6.5x47 6x47 Lapua Tactical Accuracy InternationalInitially drawn to the 6mmBR and 6mm Dasher, I realized these cartridges wouldn’t feed from an AICS magazine system without extensive modification. I took a look at the 6mm Creedmoor, 6XC, and 6mm-6.5×47 Lapua (aka 6×47 Lapua), all of which feed well from a detachable magazine. At right you can see the 6×47 Lapua in an AICS magazine. It has the “Goldilocks factor” — not too long, not too short.

The ability to simply convert 6.5×47 Lapua brass to 6×47 brass by running the parent 6.5mm brass through a full-length Forster sizing die in a single step was what made me choose the 6×47 Lapua over the 6mm Creedmoor and 6XC (both excellent cartridges in their own right). I also own a 6.5×47 Lapua rifle, so I had a supply of 6.5×47 brass ready to neck-down. Being able to create 6×47 brass easily (one pass and done) was very appealing.

Left to right, below: 6mmBR, 6-6.5×47 Lapua, 6.5×47 Lapua, and .243 Winchester.
Rifleshooter.com6mm-6.5x47 6x47 Lapua Tactical Accuracy International

I cut the chamber end off my .243 Win barrel, threaded and chambered my rifle for the 6×47 Lapua cartridge. I have written a lengthy article on this cutting and re-chambering process. Home gunsmiths interested in this process can READ MORE HERE.

When the re-chambering was complete, I headed to the range and worked up a set of eight loads using Berger 108 BTHPs, H4350, Lapua brass, and CCI 450 primers.

Rifleshooter.com 6mm-6.5x47 6x47 Lapua Tactical Accuracy International

Load development was a little trickier than with the 6.5×47 Lapua parent cartridge. The accuracy nodes were smaller. However, once I dialed in a load with Hodgdon H4350 and the 108-grain Berger BTHP, the rest was history. The 6×47 rig is now one of the most consistent rifles I own, holding just above 0.3 MOA for 5-round groups. Below is a 100-yard test target with 108-grain Berger BT in the 6×47 Lapua. Five-shot group sizes are (L to R): .369″, .289″, and .405″. The average size was .354″ or .338 MOA. [Editor: We think that is excellent accuracy for a tactical-type rifle shot from bipod.]

Norma Offers Seven New Types of Cartridge Brass for 2014

Norma cartridge brass 6.5 7mm 300 blackoutNorma is making a big push to expand its presence in the North American market. As part of this effort, Norma is introducing seven (7) new types of cartridge brass for 2014. We’re pleased to report that Norma-USA will be importing top-quality brass for the 6.5 Grendel, and 6.5 Creedmoor, two popular target cartridges. In addition, for 2014, Norma will offer 7mm RUM, 7mm Blaser Magnum, 300 AAC Blackout (300 BLK), .300 RUM, and the .338 Blaser Mag. The Norma brass we have shot in other chamberings (6 PPC, 6mmBR Norma, 6XC, .243, 7mm RSAUM) has all been excellent, giving good accuracy. Case weights were very consistent and the neck-wall thickness was very uniform, particularly with the PPC and BR brass. The new 300 BLK brass is an important offering for AR shooters. (NOTE: You can also make 300 BLK cases from Norma or Lapua .221 Fireball brass).

Though the annealing “shadow” may not be as visible as with Lapua brass, the case necks of Norma brass cartridges are indeed annealed near the end of the manufacturing process. This assures more consistent neck tension — something critical to accuracy. Most of the new cartridge brass offerings should be be available at vendors by early April, 2014. You can get Norma brass from Bullets.com, Grafs.com and Midsouth Shooters Supply, as well as many other online vendors.

New Norma-USA Brass Offerings for 2014:

  • 6.5 Grendel
  • 6.5 Creedmoor
  • 7mm RUM
  • 7mm Blaser Magnum
  • 300 AAC Blackout (300 BLK)
  • .300 RUM
  • .338 Blaser Magnum

6MM Creedmoor Brass Now Available at Good Prices

You’ve probably heard of the 6.5 Creedmoor, an excellent round for High Power and tactical applications. Well there’s a 6mm (.243) version of this cartridge — the 6mm Creedmoor. It has the same external dimensions (other than neck diameter) as the 6.5 version, but it lets you shoot the High-BC 6mm bullets at higher velocities. With a long barrel, you can push 105gr bullets an honest 3070-3100 fps with this cartridge. The 6mm Creedmoor has a large primer pocket and large flash hole (unlike Lapua’s 6.5×47 which has a small primer pocket, and small flash hole — like the 6mmBR).

accurateshooter.com GA Precision 6mm Creedmoor 6.5 brass cartridge6mm Creedmoor Brass
If you’re interested in the 6mm Creedmoor, Hornady-brand brass is available right now at reasonable prices. Yesterday, GA Precision received 110,000 pieces of 6mm Creedmoor brass. Prices are:

$65.00 for 100 pieces
$325.00 for 500 pieces
$620.00 for 1000 pieces

That works out to sixty-two cents per unit if you buy 1000 cases. CLICK HERE to Order.

We have not tested the 6mm Creedmoor cartridge yet, but we know some shooters have had good luck with it. In design, the 6mm Creedmoor is quite similar to the 6XC, which is a proven High Power cartridge that has won many championships. If you want a mid-size 6mm cartridge, with brass that doesn’t cost $1.00 per case, the 6mm Creedmoor may be an option to consider. GA Precision says this about the cartridge: “The 6mm Creedmoor is an ideal cartridge for large-platform, semi-auto rifle for shooters who wish to utilize the long, high-BC modern 6mm projectiles. Compared to the .243 Winchester, the 6mm Creedmoor case is just under .130 of an inch shorter, perfect for the confines of a short-OAL AR-style magazine. This is an ideal cartridge for competitive shooters — charges easily reach 3050-3100 FPS while coming closer to the 100% volume capacity for powder charge, often resulting in lower standard deviations recorded.”
