What we now know as the “6mm Remington” was originally called the .244 Remington. The cartridge was renamed because it was not a commercial success initially, being eclipsed by the .243 Winchester. The .244 Remington and the 6mm Remington are identical — only the name was changed. Why was the .244 Remington an “also-ran” to the .243 Win? Sierra Bullets Ballistics Technician Paul Box provides some answers…
The year was 1955. A time of carhops, drive-in movies, and Buffalo Bob. It was also the year that Winchester introduced the .243 Win and Remington counter-punched with the .244 Remington (now more commonly known as the 6mm Remington). The .243 Win was based off the time-proven .308 Win case while Remington chose the old war horse, the 7×57.
We’ve all read countless times how Winchester chose the 1:10″ twist, while Remington adopted the 1:12″ twist for their .244 Rem rifles. The first complaint in the gun magazines of that era was how the faster twist Winchester could handle 100 grain bullets, while Remington’s [12-twist factory rifles were supposedly limited to 90 grain bullets].
The first complaint I remember reading was that the 100-grainer was better suited for deer-sized game and the 1:12″-twist wouldn’t stabilize bullets in this weight range. Now, let’s look at this a little closer. Anybody that thinks a 100-grainer is a deer bullet and a 95-grainer isn’t, has been drinking too much Kool-aid. In all honesty, it’s all about bullet construction and Remington had constructed the [90s] with light game in mind. In other words, Remington got it right, but due to a lack of knowledge at the time on both bullet construction and stability, the .244 never gained the popularity it deserved. At that time, Sierra had the 100gr SMP and Hornady offered a 100gr RN that would both stabilize in the slower 1-12″ twist. The .244 Remington provides another classic example of how the popularity of a cartridge suffered due to a lack of knowledge.
.244 Rem vs. .243 Win — What the Experts Say
Respected gun writer Chuck Hawks says the .244 Remington deserved greater acceptance: “The superb 6mm Remington started life in 1955, the same year as the .243 Winchester. It was originally named the .244 Remington. Although the 6mm lost the popularity contest to the .243, it is one of my favorite rifle cartridges, and much appreciated by reloaders generally. The .244 Rem and 6mm Rem cartridges are completely interchangable, and anyone with a .244 Rem rifle can shoot [6mm Rem] ammunition in complete safety (or vice-versa). Remington .244 rifles made from 1958 on can stabilize all 6mm bullets, while those made in 1955 through 1957 are limited to loads using spitzer bullets not heavier than 90 grains for best accuracy.”
Nathan Foster, author of The Practical Guide to Long Range Hunting Cartridges, states: “In 1963 Remington attempted to regain ground by releasing .244 rifles with a new 1:9″ twist to handle heavier bullets. The cartridge was renamed the 6mm Remington and new ammunition was loaded giving the hunter the choice of either an 80gr bullet for varmints or a 100gr bullet for deer. In comparison to the .243 Win, factory loads for the .244/6mm Remington are slightly more powerful while hand loads increase this margin further.”
Was the .244 Remington Actually Better than the .243 Winchester?
The .244 Remington (aka “6mm Remington”) has a velocity advantage over the .243 Winchester due to a slightly larger case capacity. The longer case neck of the .244 Remington is considered desirable by handloaders. We like the added capacity and long neck of the original .244 Remington. As renamed the “6mm Remington”, the cartridge HAS developed a following, particularly with varmint hunters looking for a high-velocity 6mm option. But it never achieved the success of the .243 Winchester for many reasons. As a member of the .308 family of cartridges, the .243 Winchester has certain obvious advantages. First, you can simply neck down .308 Win brass, which was available at low cost from many sources. Moreover, a .308 Win or 7mm-08 full-length sizing die could be used for body sizing. Still the .244 Remington (6mm Remington) presents an interesting “what if?” story…
Gun guys are always shipping stuff around the country — whether it’s a barrel to be chambered, or a scope that needs to go back for warranty repair. Or maybe you’ve sold some bullets or reloading dies you no longer need. To ensure your precious packages get to their destination in one piece, it’s important to take precautions when boxing up your items. And by all means insure packages for full value — even if your packaging is perfect, there is always the possibility that your shipment might be lost altogether. Sadly, that can happen, no matter which carrier you choose: Fedex, UPS, or the U.S. Postal Service (USPS). Here are some tips for shipping gun stuff — we explain how to pack items properly and how to minimize the risk of loss.
Tips for Shippers
Dennis Haffner from McGowen Precision Barrels offers some advice on how to avoid damage when shipping gun parts or other valuable or heavy items. Dennis explains:
“First, I started double-packing the contents and in many cases double-boxing. I spend a fortune on heavy-reinforced shipping tape. If the contents are loosely packed, the package is going to get crushed. On real important items or delicate items, wrap the content in plastic and spray the inside void areas with non-expanding foam. They make shipping foam just for this. This method really works. Since I started paying more attention to packaging, I have just about wiped out my issues with all three companies (Fedex, UPS, USPS). Yes, I hate doing it, but in the long run for us, it’s cheaper.
Bullet shipments are the worst — a shipment of 500+ bullets can destroy a cardboard box. I have ordered bullets from individuals who put them in baggies and filled the remainder of the box with foam peanuts. That is not going to work. Any piece of metal, including a die, will puncture a cardboard box, or destroy a padded envelope. Just look at the tracking information and imagine your package bouncing around in the back of the shipping truck, probably under many other packages. My advice is to NEVER use padded envelopes. Barrel nuts or recoil lugs will most likely never make it.
ORM-D items are required to be shipped in heavily-reinforced, double-walled containers. The packages still get a little damage, but the contents usually survive.
How do shipments get damaged? Consider this — one of the shipping companies this year flipped (overturned) one of our new CNC machines (which rendered it useless). Maybe your small packages were in the same delivery truck as my CNC machine. I wonder how many little boxes were crushed underneath it.
As for USPS flat rate boxes — you would not believe what people try to stuff in these boxes. USPS finally put a weight limit on the boxes — they had to. I sometimes take my delicate items packed in an envelope or small box. I spray foam in a larger flat rate box and insert the smaller package, then fill the remainder of the void with foam. It works, and part usually arrives undamaged.”
Shipping Rifle Barrels (PVC Tube and Tennis Ball Method)
A new match-grade barrel can cost $350 or more, and it might take six months (or more) to replace it, given the current wait time with top barrel-makers. So, you don’t want your nice new tube to get damaged in transit. Forum Member Chuck L. (aka “M-61″) offers these tips for shipping rifle barrels:
“Packing a barrel can be a problem. Here’s a shipping method that won’t stop lost shipments but so far has stopped damage. Get a PVC pipe (of size appropriate to your barrel) with fitted caps for each end. Attach a cap to one end. Tape the barrel threads and tape over the muzzle. Then drop one standard tennis ball into the pipe. Place barrel in pipe. Next add whatever peanuts or foam you can jam in to support the barrel on the sides. Then place a second tennis ball into the opposite end of the PVC pipe. (So now you have a tennis ball on either end of your barrel.) With everything secure inside, attach the upper cap and tape it down securely. With this packing procedure, when the carrier launches the pipe like a javelin, at least the barrel will not come through like a spear and be gone. Label the pipe with very large address labels so no one suspects it’s just garbage laying around. This procedure may seem ridiculous but it has worked for me. Oh and definitely get insurance. If your item is insured, the shippers will look harder to find it.”
Editor’s Note: Fedex also makes a triangular-profile cardboard shipping box. This 38″ x 6″ x 6″ x 6″ Fedex Tube (designed for blueprints and posters) is free for the asking. For most barrels, there should be enough clearance to hold your PVC tube (with barrel packed inside tube). However, don’t ship the barrel inside the cardboard box by itself. Cap and pad the ends and bubble wrap it heavily, or better yet, use the PVC tube method described above, with the PVC tube inside the box.
Our friend Bill Marr of Rifleshooter.com has done it again — conducted a fascinating 6mm Creedmoor barrel cut-down test that reveals how velocity changes with barrel length. This time Bill started with a 24″ Proof Research stainless steel barrel on a Howa action. Bill says this was a well-used barrel, with over 1800 rounds through it. So, the velocities might be a bit different than a new barrel of similar length. Bill cut the barrel down in one-inch increments. Here are some results from the test:
For this latest test, Rifleshooter cut the barrel in one-inch increments from 24″ to 16.1″ (just over legal minimum). Velocities were measured with a MagnetoSpeed V3 chronograph mounted on arm attached to the stock. This allowed the chrono to be adjusted inwards as the barrel was cut shorter, inch by inch.
For the 6mm Creedmoor cartridge, Bill loaded Hornady 108gr ELD Match bullets over 41.5 grains of Hodgdon H4350 with CCI 200 primers in new Starline brass.
The results were interesting to say the least. Bill reports: “Muzzle velocities ranged from 2,893 ft/sec at 24″ to 2,598 ft/sec at 16″ for a decrease in muzzle velocity of 295 ft/sec. Muzzle velocity changes per inch of barrel length ranged from 6 ft/sec per inch between 20 and 19 inches to 63 ft/sec per inch between 19 and 18 inches. Average velocity change per inch of barrel length was 37.9 ft/sec.”
Bill concludes: “An average drop of 37.9 ft/sec/inch of barrel is fairly significant and is what would be expected with a fast moving 6mm cartridge like the 6mm Creedmoor. While I’m used to seeing 6mm Creedmoors with slightly longer barrel lengths than 24″, when coupled with a sound suppressor the additional length can make moving the rifle quickly more difficult.
I’d suggest staying with longer barrel lengths wherever possible with this cartridge. At shorter lengths, it does give up more performance than its big brother the 6.5 Creedmoor.”
More 6mm Creedmoor Velocity Data from 2017 Cut-Down Test
If you’re curious about 6mm Creedmoor velocities at longer barrel lengths, back in 2017 Rifleshooter completed a 6mm Creedmoor barrel cut-down test from 31 inches all the way down to 17 inches. The test included four bullet types from 95 grains to 110 grains. With the 110gr Sierra MK, velocity at 31″ was an impressive 3110 fps. Surprisingly the velocity didn’t decrease that much for the first few inches. Even at 26″ (a five-inch reduction), measured velocity with the 110s was 3073 fps, a loss of 7.4 fps per inch on average. With a barrel shortened all the way to 20″ however, velocity had dropped down to 2949 fps, a significant (161 fps) loss. CLICK HERE for complete results from that 31″-17″ Barrel Cut-Down Test.
by Sierra Bullets Ballistic Technician Philip Mahin for Sierra Bullets Blog
A lot of calls that come into the Sierra Customer Service Center are made by shooters [of retirement age]. Most of the time the shooter used to reload back when they were [younger] and stopped in order to raise a family, pursue a career, or both. Maybe their father or grandfather taught them back in the day and they are looking for an answer to the new whatchamacallit they found on the internet. The point is they are coming back to it because it was fun.
Reloading Can Provide Stress Relief
As a father of three, a husband, a brother, a son and son-in-law, and a friend and neighbor, I get pulled in a lot of directions. In all honesty, reloading and shooting has become a stress relief for me even though I work in the shooting industry.
Sometimes, the shooting gets put on hold for other more important things but there will always be another project or repair to accomplish. There are a lot out there that have found a way to balance the work life, the family life, and the play life. I would like to applaud you on your efforts because it is a hard thing to accomplish.
Remember to take time and relieve that stress. Do something fun, especially if it is shooting that special hand-load you just made.
AccurateShooter Comment — Hand-Loading and the Creative Process
Reloading your own precise ammo can be rewarding in many ways. First it allows you a temporary escape from work pressures, “Honey-Dos”, filing your taxes — whatever. It’s just you and Mr. Rockchucker spending quality time in the loading room. Second, hand-loading is a creative process that engages the mind. During load development, you are like an inventor, selecting a powder charge, choosing the bushing size, experimenting with seating depths, working to perfect your load.
Lastly, the process of hand-loading is rewarding because you are building something start to finish. You begin with components — bullets, brass, and powder, and end up with a finished product that (hopefully) is better than the best factory ammo you could buy. It is enormously satisfying to start with piles of bullets and brass and end up with beautiful hand-loads that can deliver great accuracy.
At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, optics, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
If you enjoy hunting small varmints (such as ground squirrels), or plinking out to 200 yards, you really should get a 17 HMR. This little rimfire cartridge is very effective on small varmints and is much flatter shooting than a .22 LR. What 17 HMR to buy? Well if you’re on a tight budget, consider the Rossi RB17. This handy bolt gun boasts a nicely designed stock, a 5-round magazine, 21″ barrel, plus scope bases attached to the action. And you can get one for under $140! Right now the RB17 is just $135.99 at Gensec Armament and $136.48 at Guns Midwest. (Compare More Vendors).
2. Krieger Barrels — Discounted Overstock Barrels
Krieger barrels have a strong tradition of being at the top of leaderboards year after year. But like any good barrel company they often need to be ordered months ahead of time. A little-known secret is that Krieger maintains a supply of Krieger overstock barrels that are priced to move and available right now. These are absolutely first-run quality, but just represent excess volume in particular contours and calibers. We’ve ordered Krieger overstock barrels and have never been disappointed — especially when the barrel shows up a week later.
3. Grizzly Industrial — Bald Eagle Slingshot Rest, $129.97
Maybe you’re just getting into F-Class or just need a good stable front rest to shoot from and don’t want to spend a ton of money on one. Don’t worry because Grizzly now has the Bald Eagle BE1129 aluminum slingshot rest for an amazingly low $129.97 Closeout price. Just add your favorite front bag and you’re ready to go with a competition quality elevation adjustable rest. They also have the Bald Eagle BE1209 – Big Fifty Rest on sale now for $205.00, nearly 50% off. With a much wider span and cast-iron legs, the Big Fifty is designed for larger guns up to .50 caliber. Either way, these rests are a great value.
4. Bullet Central — Buy BAT Action + Bix’N Andy Trigger, Save $50
BAT actions are certainly some of the finest actions on the market. Likewise, Bix’n Andy triggers are some of the very best triggers. However, it’s rare to see either of them on sale. For a limited time, Bullet Central is offering a $50 DISCOUNT with the purchase of a Bat action plus a Bix’n Andy trigger. This is about as good a deal as you’ll find on either product. If a new gun build is in your future this is a good time to pick up a premium action and trigger and save some bucks in the process.
5. Amazon — Caldwell Stable Table Lite, $109.99
Here’s a great product for varmint hunters, and shooters who test their rifles in locations without fixed benches. Yes there are other portable benches, but these may weigh over 120 pounds and cost hundreds of dollars. The Caldwell Caldwell Stable Table Lite is a affordable, transportable option. The stable table weighs under 30 pounds and costs about $110.00. That makes it very viable as a movable varmint bench. This weatherproof folding table folds flat and is only about 8″ thick when packed up.
Photos don’t do this product justice, guys. You should really watch the video to see how the Stable Table Lite works. The video shows how the table deploys easily and how you can swing the seat to either side. Any shooter looking for a light-weight, affordable, easily-transported shooting table should definitely consider this product.
6. Taurus G2c 9mm — $184.99 with Factory Rebate
This is a good little gun at a great price. Taurus is running a factory rebate through the end of May 2019. Palmetto State Armory has the OD Green-frame Taurus G2c 9mm for just $209.99 with FREE shipping. But the Taurus $25 Factory Rebate lowers your price to just $184.99 for this G2c. Or, if you like basic black, you can get a black-framed G2c for $174.99 after rebate. Despite its small size, the G2c has a 12-round magazine. We like the fact it has a left-side manual safety (unlike the Glock).
Are you checking your headspace to ensure you’re pushing your shoulders back the correct amount? If you’re aren’t using a tool like the Hornady Headspace Gauge with 5 bushings then you are just guessing and you’ll never know for sure. Using one of the headspace gauges is one of the best ways to control your full-length sizing and thereby improve the consistency of your handloads.
Right now CostCo is offering the Cannon CS72 Executive Series 72-Gun Safe for just $749.99 DELIVERED! That’s a great price for a HUGE safe with 43.8 cubic feet of internal space. This 649-pound behemoth measures 59″H x 45″W x 28″D and weight 696 pounds (over 1/3 of a ton!). This is built strong with 1″ thick composite door, six 1″-diameter locking bolts, and 60-minute fire rating. NOTE: The $749.99 price includes “Standard shipping via common carrier” to the lower 48 states. This is a great value. You could easily pay $1600 or more for a safe this size from a local vendor.
9. Amazon — Caldwell Front and Rear Bag Set (Unfilled), $20.16
This is a functional, “field expedient” system that’s easy to haul around and only costs $20.16. Varminters can keep these bags in a vehicle for deployment any time. Act quick — this is a special sale price at Amazon.com. This unfilled bag combo sells for up to $33.00 elsewhere. This inexpensive system works surprisingly well, particularly with “standard” rifles with narrow fore-ends. Rather than sand, you can fill with rice or media to make the bags lighter. This system features a heavy-duty clip and D-Ring for linking the two bags for easy carry. Caldwell DeadShot bags are crafted from durable, water-resistant 600 denier polyester. Bag dimensions (filled) are: FRONT 11″ x 8.5″ X 6″; REAR 5″ x 5″ x 4.5″.
Gary Costello recently won the Great Britain National League 600-yard Championship in F-Open class. Gary managed that impressive win despite Storm Hannah which caused torrential rain and 40 mph winds during the match, held at the Diggle ranges. Gary, a Forum member, reports that conditions were hellacious: “The weather was terrible, with horizontal rain and winds in excess of 40 mph. In fact, some shooters got blown clean off the target and many complete misses occurred.”
There’s a special story here, as Gary had been battling a life-threatening illness for many months. Gary told us: “This was my first National Competition since September 2018. I contracted a serious heart virus in October 2018. I was critically ill until January 2019. After undergoing treatment and 100% rest I recovered slowly, my focus was the 600-Yard Shoot in April. I am now 70% there and hopefully in another 4-6 months I hope to make a full recovery.” [Editor: Gary, we are glad you are on the road to recovery.]
In today’s Sunday GunDay story, we feature Gary’s American-crafted .300 WSM F-Open rifle. Note that Gary’s rifle has a Ezell barrel tuner and a recoil-reduction system in the buttstock. The .300 WSM does generate quite a kick with those big .30-caliber bullets.
Gary Costello’s .300 WSM F-Open Rifle
BAT M Action and Cerus Stock
This rifle was purchased from Jim Fowler (FalconPilot on the AccurateShooter Forum). This SG Rifles gun, crafted by smith Thomas “Speedy” Gonzalez, is a .300 WSM with BAT ‘M’ action (with nitrided bolt) and Cerus riflestock. Gary owns two other Speedy-built rifles.
Gary tells us: “My BAT ‘M’ action is a multi-port so I feed with my left and it ejects on the right. Speedy has worked on the firing control and timing, and I fitted the roller-cocking piece to aid smoothness and speed.” The fluted shroud is Speedy’s signature for fire control work.
Stunning Lenzi Co-Axial Front Rest
Gary tells us this impressive joy-stick rest “is a superb piece of engineering .. made by my good friend Alberto Lenzi.” Note the large stable base, and the deluxe counter-balance weight on the front end. Gary also uses a very nice leather rear sandbag crafted by Lenzi.
Riflescope — Prototype March 10-60×56 High Master
Gary Costello’s company is the European distributor for March Scopes. Gary was testing this scope as it has a new temperature-tolerant lens system to be released later this year
.300 WSM Load Details — H4350 with Berger 215gr Hybrids
Gary was shooting pointed Berger 215gr Hybrid bullets in Norma .300 WSM cartridge brass. The powder was Hodgdon H4350 with Muron KVB7 primers. Gary say his load runs around 2850 fps, and is very accurate. To demonstrate, here is a three-round, 100-yard test target, with a group measuring in the ones. Pretty impressive for a big bullet and a short magnum cartridge.
The UK has some wonderful places to shoot. This photo was taken at Blair Atholl in the Highlands of Scotland. Gary says “This is one of my favorite ranges and probably the hardest range to shoot in the UK. Due to the topography of the range you have to alter elevation as well as wind for pick-up and let-off. They say ‘Diggle Ranges Bark’ but Blair Atholl Bites!”
Blast from the Past — At Blair Atholl Ranges in Scotland
One of Europe’s very best F-Class competitors, Gary is no stranger to the winner’s circle. Here he is at the Blair Atholl Ranges in Scotland after a major victory a few seasons back. Gary says: “Blair Atholl, in the Estate of Blair Castle, is very scenic. The range is very tricky and is known as the hardest range in the UK to shoot due to the location of the targets cut into the hillside and valley. When the wind is at full value you often have to add one-half MOA elevation to every 1 MOA of wind. So thinking wind and elevation every shot is very difficult. I won this match some time ago and I do not recall the score. However it was a decisive win, and all matches in the competition were held at 1000 yards.” Gary was using a different rifle, but it also was a .300 WSM with a BAT action. His load was Hodgdon H4831 with Berger 215gr Hybrids, Murom primers, and Norma brass.
The event was the first GB National League event of the year, our only short range (600-yard) match. This is actually one month later than usual in hope the weather would be better, sadly that wasn’t the case!
I won the Championship, five points clear of runner-up Ian Boxall. My final score was 241-18V out of a maximum of 250. The course of fire was reduced due to Storm Hannah on Saturday. It was decided by our committee that for safety we should shoot under cover (Diggle has a 600-yard covered firing point). The goal was to get at least one match to allow the competition to continue on the Sunday.
When I saw the condition and the flags I decided I needed to shoot as quick as possible as wind speed and direction were changing in seconds….
So I shot like stink only watching one flag and the other targets and my shot indication on the target screen. My first sighter was a score One left (a FIVE on the U.S F-Class target). But after adjusting, my second sighter was a One right — so there were pick-ups and let offs of about FIVE MOA!
I split the difference and went for score, my first shot was a Four (Nine on USA target) which I then adjusted on and held accordingly for the rest of the string using the other targets as indication and the one flag I had identified, it went pretty well.
Day Two (Sunday) weather was completely different, much better with no rain. We were first up at 0900 and the winds were light with subtle changes. This was a two sighters and 20-shot match, I started well with two V sighters which were converted, my partner Richard Sharman also had a good start and we proceeded through the string shooting Vs and Fives until Richard’s shots started to not register, this happened three times so it was decided I would continue and Richard would shoot again on another target. This caused a lot of delay and disruption. I had lost my path and wind, due to the delay I was allowed a non-convertible sighter which was a Three. It took two further shots to get back into the swing and I then recovered and ended the shoot with a 97-10V.
For the Final Match, the wind had picked up and was causing quite a few lost points and curses. I knew I was three points clear going into this Final Match so I had to play it real safe not to drop shots and lose critical points. I favored a left 4-5 Ring hold so not to get caught on the pick-ups. I use the March MTR-2 reticle, on 40X this reticle is subtended at exactly one-half MOA and brackets the F-class target perfectly. I was not concerned about the V bull at this time, the plan paid off and I dropped two points only.
The 6.5 Creedmoor cartridge is now one of the most popular cartridges for new factory rifles. Ruger, Savage, Howa and other gun-makers all offer 6.5 Creeemoor rifles. The 6.5 CM has been a leading cartridge for tactical/practical gun games (although many shooters have moved to a 6mm Creedmoor or even a 6mm Dasher). It offers excellent ballistics, moderate recoil, and good accuracy with a variety of powder and bullet combos. Along with the 6.5×47 Lapua, the 6.5 Creedmoor has demonstrated that a .264-Caliber mid-sized caliber is truly a jack of all trades — it can be accurate on paper, win PRS matches, and also harvest game during hunting season. If you own a 6.5 Creedmoor (or plan to get one) and hand-load your ammo, this post should provide a good start. Sierra Bullets now offers 6.5 Creedmoor Load Data for bullets from 120 to 142 grains — the most popular weight range for this chambering.
Sierra Bullets has 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.
The Springfield M1A is now available in 6.5 Creedmoor. For Gas Guns like this, be sure to full-length-size your brass after every firing, with adequate shoulder bump.
Developed 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, Reloder 16, Varget, and IMR 4451. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power and PRS matches, and in the hunting fields. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success.
Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.

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.
Cartridge Efficiency: A Primer (pun intended!)by USAMU Staff
Each week, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading article on its Facebook Page. In this week’s 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 careful] 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
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.”
Do you shoot a Springfield M1A rifle chambered for the .308 Win/7.62×51? Or maybe you have a rugged, semi-auto FN-FAL in 7.62×51 NATO? Are you looking for very strong, durable brass you can shoot in these semi-auto battle rifles, without breaking the bank?

Semi-autos such as the M1A are tough on brass. You want brass that isn’t too costly, but at the same time is very strong and durable. For decades, USA-made Lake City brass have been a solid choice for 7.62×51 semis, and now you can get quality, unfired 7.62×51 Lake City brass for just $49.99 for 250 cases at Midsouth. That’s just $0.20 (twenty cents) per case! That’s a fourth what you’ll pay for premium, virgin .308 Winchester brass. These cases are never-fired brass, with CCI #34 primers seated in crimped, military-style primer pockets.
This 7.62×51 Lake City brass comes from disassembled “pull-down” ammunition. It has NOT been fired, but it has been previously assembled. So, there may be some cosmetic issues with the brass. Note that these are primed cases. If you choose to neck-size or FL-size the brass before loading for the first time, REMOVE the decapping rod in your sizing die. This brass has LIVE PRIMERS!! Do NOT use a die with a decapping rod for the first loading of this brass. Got that guys? This is important!!
We have shot FN-FAL-type rifles built on DS Arms semi-auto lowers with European uppers. Those beasts were tough on brass, so we relied on Lake City brass when available. If you have a FN-FAL or STG-58, you should give this Lake City primed, pull-down brass a try. (Federal Gold Medal Match ammo shot great in our DSA/STG-58 but the brass was toast after a few firings).

Loading at the range remains important in the Benchrest for Group discipline. In a Special Report below, IBS President Jeff Stover explains how loading methods (and hardware) have evolved over the years. The advent of accurate, affordable electronic powder dispensers, such as the RCBS ChargeMaster and Frankford’s new Intellidropper, have changed the game and made it easier to load efficiently at the range. And quality manual powder measures are fast and can be very consistent, with a little practice. Loading at the range permits competitors to tune their load to the conditions, change seating depths, or even choose different bullets to suit the barrel’s preferences on any given day.
Although pre-loading is not uncommon, most 100/200-yard group shooters usually load at the match, often between relays. The goal is to shoot smaller groups by staying “in tune”. In a game where 5-shot groups “in the 1s and Zeros” is the goal, tuning loads for the conditions helps deliver match-winning accuracy. Nearly all competitors in this short-range discipline shoot the 6mm PPC cartridge, or a PPC variant.
Loading at the Range — Then and Now
In benchrest shooting for group, loading at the range has been de rigueur for decades. In the Score discipline, preloading is usually the custom. The main reason is that, in Score competition, only one Aggregate (warm-up match and five record targets) per day is usually shot. That would be less than 50 shots, assuming a few sighter shots. Also, the 30BR, the dominant Benchrest-for-Score cartridge, is very amenable to pre-loading.
By contrast, the Group discipline includes 21 targets (two warm-ups and twenty record targets) over a weekend, usually shot with 6PPC-chambered rifles. Many times, the 6PPC shooters may tweak their loads through the day given changing atmospheric conditions or simply trying to find the correct tune to “dot up”. This term, “Dot up”, means the shots are essentially going through the same hole, or closely so.
Loading at the range was a bit different when benchrest competition was in its infancy. The 1951 book, Modern Accuracy by Bob Wallack, is the best of the early benchrest books. Copies can be found, from time to time, on eBay or Alibris. It is a fascinating survey of benchrest as it existed more than six decades ago. There’s even coverage of a controversial target that was argued over at the time. In it, there is a photo of Wallack using the rear bumper of a car at the bench to clamp his reloading tools. Things have come a long way compared to the range loading set-ups of modern shooters. Here you can see Bob Wallack way back in 1950:
Modern loading bench set-ups shown in this Special Report belong to top shooters Howie Levy, Bob Hamister, and Kent Harshman.
Gun guys are always shipping stuff around the country — whether it’s a barrel to be chambered, or a scope that needs to go back for warranty repair. Or maybe you’ve sold some bullets or reloading dies you no longer need. To ensure your precious packages get to their destination in one piece, it’s important to take precautions when boxing up your items. And by all means insure packages for full value — even if your packaging is perfect, there is always the possibility that your shipment might be lost altogether. Sadly, that can happen, no matter which carrier you choose: Fedex, UPS, or the U.S. Postal Service (USPS). Here are some tips for shipping gun stuff — we explain how to pack items properly and how to minimize the risk of loss.
“First, I started double-packing the contents and in many cases double-boxing. I spend a fortune on heavy-reinforced shipping tape. If the contents are loosely packed, the package is going to get crushed. On real important items or delicate items, wrap the content in plastic and spray the inside void areas with non-expanding foam. They make shipping foam just for this. This method really works. Since I started paying more attention to packaging, I have just about wiped out my issues with all three companies (Fedex, UPS, USPS). Yes, I hate doing it, but in the long run for us, it’s cheaper.
How do shipments get damaged? Consider this — one of the shipping companies this year flipped (overturned) one of our new CNC machines (which rendered it useless). Maybe your small packages were in the same delivery truck as my CNC machine. I wonder how many little boxes were crushed underneath it.
“Packing a barrel can be a problem. Here’s a shipping method that won’t stop lost shipments but so far has stopped damage. Get a PVC pipe (of size appropriate to your barrel) with fitted caps for each end. Attach a cap to one end. Tape the barrel threads and tape over the muzzle. Then drop one standard tennis ball into the pipe. Place barrel in pipe. Next add whatever peanuts or foam you can jam in to support the barrel on the sides. Then place a second tennis ball into the opposite end of the PVC pipe. (So now you have a tennis ball on either end of your barrel.) With everything secure inside, attach the upper cap and tape it down securely. With this packing procedure, when the carrier launches the pipe like a javelin, at least the barrel will not come through like a spear and be gone. Label the pipe with very large address labels so no one suspects it’s just garbage laying around. This procedure may seem ridiculous but it has worked for me. Oh and definitely get insurance. If your item is insured, the shippers will look harder to find it.”
For this latest test, Rifleshooter cut the barrel in one-inch increments from 24″ to 16.1″ (just over legal minimum). Velocities were measured with a 
Developed 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).
