We’ve been fans of the Howa Mini Action rifles since they were introduced a couple years ago. With actions that are nearly an inch shorter than typical “short actions”, these Mini Action rigs work great as a compact “truck gun” or carry-around varminter. Current chamberings are: .204 Ruger, .222 Rem, .223 Rem, 6.5 Grendel, and 7.62×39. There are 20″ lightweight, 20″ heavy contour, and 22″ standard contour barrel options.
6.5 Guy Ed Mobley Tests the 7.62×39 Howa Mini Action Rifle
The Howa Mini Action rifles come with the excellent HACT 2-stage trigger and a 5-round or 10-round, synthetic detachable box mag (depending on caliber). The Mini Action’s bolt is 13% shorter than on regular short actions, providing a shorter, faster bolt throw. Weight is also reduced. This makes for a nice, compact (and very shootable) package.
6.5 Guys Test Howa Mini Actions in 6.5 Grendel and 7.62×39
The 6.5 Guys recently secured a pair of Howa Mini Actions, one chambered in 6.5 Grendel and the other in 7.62×39 Russian: “After trying out the Howa Mini Action rifles at SHOT Show 2017, we got a couple of loaners in 6.5 Grendel and 7.62×39 courtesy of Legacy Sports. These rifles are known for their smooth cycling and lightweight actions, as well as some unique chamberings for bolt rifles (6.5 Grendel, 7.62×39). Long story short, we really enjoyed them.” In fact Steve liked his 6.5 Grendel enough that he plans to purchase the gun. Get the full scoop in this VIDEO REVIEW:
The folks at Legacy Sports also conducted extensive accuracy tests of commercial ammunition in 6.5 Grendel and 7.62×39. The most accurate 6.5 Grendel ammo, with a stunning 0.29″ group, was Alexander Arms with Lapua 123gr Scenar; second best (0.56″ group) was Hornady with 123gr A-Max bullet. The most accurate 7.62×39 ammo was Hornady 123gr SST with a 0.62″ group in the 20″ Heavy Barrel version. View Howa’s Test Reports with these links:
This is a very interesting development. Federal will produce a line of Federal Gold Medal ammunition loaded with Berger Bullets match projectiles and GM Match primers. The new Gold Medal Berger ammo will initially be offered for: .223 Remington, 6.5 Grendel, 6.5 Creedmoor, and .308 Winchester. We expect this ammo to attract the attention of tactical and PRS shooters — Berger projectiles are currently favored by top PRS competitors. Depending on caliber, three different high-BC bullet types will be used: BT Target, Hybrid OTM, or Juggernaut OTM. These all feature a boat-tail design with a high BC for bullet weight. The 6.5 calibers will use Berger’s popular 130gr Berger Hybrid OTM bullet while the .308 Win uses the 185gr Juggernaut.
This new Gold Medal Berger ammo uses Federal Gold Medal match primers, Federal brass, and specially-formulated propellants. All the ammo is well under SAAMI-spec max OALs to function 100% in magazines. Federal says this ammo will “adhere to Federal Premium’s strictest specifications for accuracy, pressure and velocity”. This new GM Berger ammo line could be a match-worthy alternative for guys who don’t want to hand-load. We’re going to try some in 6.5 Creedmoor and see how it performs in terms of accuracy, ES/SD, ballistics, and temp stability. Should be an interesting test…
FEATURES of Gold Medal Berger Ammo:
• Most popular bullets at Precision Rifle Series events
• High ballistic coefficient
• Less wind drift and drop (than typical factory ammo)
• Excellent long-range accuracy
• Gold Medal match primer
Sometimes everything comes together — a great barrel, the right load, good bullets, and, of course, a gifted trigger-puller. Check out this target from Forum member Mike Ezell. That’s five (5) shots at 100 yards from Mike’s 30 Major benchrest rifle. When this group was shot a while back, Mike reported: “I fired a few groups in the great weather. No surprises — it did VERY well! My little wildcat, the 30 Major, has always been a shooter. That target was not a fluke — I shot a few groups today and Agg’d a high One.” Mike is a Kentucky gunsmith who builds his own rifles.
30 Major is Based on 6.5 Grendel
What’s a “30 Major” you ask? This is Mike’s own wildcat, a 6.5 Grendel necked up to .30 caliber. Mike writes: “The 30 Major is essentially a .070″-long 30 PPC. With the great 6.5 Grendel brass available from Lapua, all you need to do is neck-up and turn the necks to prep the brass.” Mike says it is very much like a 30 BR, but you just start with 6.5 Grendel brass instead of 6mmBR brass.
The cartridge has one major benefit — it utilizes a PPC-diameter bolt face. That makes it easy to convert your group-shooting 6 PPC to shoot score with .30-cal bullets. Mike explains: “If you have a PPC, to shoot score, all you have to do is chamber up a [.30 caliber] barrel and screw it on your PPC.”
From 7.62×39 Russian to 30 Major — Full Circle
Arms expert Neil Gibson has an interesting perspective on the lineage of the 30 Major. He reminds us that this wildcat has returned to its roots: “Start off with the 7.62×39 Russian [cartridge]. The Russians then modify it, necking it down to .223 for deer hunting. The U.S. benchrest guys then modify that, necking it up to 6mm and blowing the case out making the 6mm PPC. Someone takes that case, necks it out to 6.5 mm, making the 6.5 PPC. Alexander Arms takes that and makes the 6.5 Grendel. Then finally Mike Ezell takes the Grendel and necks it up to 30 caliber, making the 30 Major. From 30 caliber, back to 30 caliber. OK, the original uses .31 caliber bullets, but the bore is still .300. Talk about almost coming round full circle!”

Great Accuracy Restored after Solving Mystery Problem
To get his 30 Major rig shooting this well, Mike had to solve a mysterious problem that cropped up last year. Mike explains: “Two years running, I have finished in the top 15 in IBS points shooting [the 30 Major], but last year’s benchrest season was tough.” Mike was having some accuracy issues that defied explanation. But he figured it out: “The front action screw was bottoming out against the barrel extension – just barely. A simple fix brought the gun back to life. It’s a Stiller Viper Drop Port. The action is screwed and glued into the stock, so I was a bit surprised … especially after having checked for [that issue] while looking for the problem. I’m just glad to have found the trouble so I can begin to re-instill some confidence in the gun and myself, after last year.”
Do you shoot a mid-sized match cartridge, such as the 6.5×47 Lapua, or 6.5 Creedmoor? Then here’s a great deal for you. Right now you can get 123gr Nosler HPBT match bullets for just $20.49 per hundred. These are on sale as “factory seconds” with cosmetic blemishes, such as water spots. But they are otherwise fine bullets, and your targets will never notice the blemishes.
We prefer bullets in the 120-130 grain weight range for the mid-sized 6.5mm cartridges. While you give up a little BC compared to the 140s, the lighter bullets seem to be easier to tune and often group tighter. You can also get significantly higher velocities with a 120-grainer compared to a 140-grainer. The extra velocity may allow you to reach a higher accuracy node. With our .260 Rem, we got consistently better inherent accuracy with 120gr bullets running at a high node, compared to the slower moving 140s. YMMV, but we think it’s worth trying these Noslers at just $20.49 per box — half the price of some other premium 130gr 6.5mm match bullets.
Bullets in the 120-grain range often shoot very well in all these cartridge types. And they may be easier to tune than 140-grain class 6.5mm projectiles.

One of our forum members was looking for a very accurate, mid-sized 6.5mm cartridge for target working and coyote hunting. There are many great options including the 6.5 Grendel, 6.5×47 Lapua, 6.5 Creedmoor, and Remington .260 (a 6.5-08). If you are considering the 6.5×47 you should read our 6.5×57 Cartridge Guide authored by the 6.5 Guys. This and other 6.5mm cartridges are covered in this introduction to 6.5 mm cartridges prepared by Eben Brown, President of Eabco.com.
Guide to 6.5mm Cartridges
by Eben Brown, EABCO.com, (E. Arthur Brown Co. Inc.)
The current popularity of 6.5mm cartridges in the USA has been a long time in coming. I won’t go into my opinions on why it took so long to catch on. The important thing is that it finally HAS caught on and we’re now so fortunate to have a wide selection of 6.5mm cartridges to choose from!
6.5mm Grendel – Developed by Alexander Arms for the AR15 and military M4 family of rifles. The Grendel fits the dimensional and functional requirements of these rifles while delivering better lethality and downrange performance. There are now similar cartridges from other rifle companies. We chamber for the Les Baer “264 LBC-AR”. Designed for velocities of 2400-2500 fps with 123gr bullets, it shoots the 140-grainers at about 2000 fps (for comparison purposes).
6.5mm BRM – Developed by E. Arthur Brown Company to give “Big Game Performance to Small Framed Rifles” — namely our Model 97D Rifle, TC Contender, and TC Encore. Velocities of 2400-2500 fps with 140gr bullets puts it just under the original 6.5×55 Swede performance.
6.5mm x 47 Lapua – Developed by Lapua specifically for international 300m shooting competitions (with some interest in long-range benchrest as well). Case capacity, body taper, shoulder angle, and small rifle primer are all features requested by top international shooters. You can expect velocities of 2500-2600+ with 140 gr bullets.
6.5mm Creedmoor – Developed by Hornady and Creedmoor Sports, the 6.5mm Creedmoor is designed for efficiency and function. Its shape reaches high velocities while maintaining standard .308 Winchester pressures and its overall length fits well with .308 Win length magazines. You can expect velocities of 2600-2700+ fps with 140gr bullets.
.260 Remington – Developed by Remington to compete with the 6.5mmx55 Swedish Mauser that was (finally) gaining popularity in 1996. By necking down the 7mm-08 Remington to 6.5mm (.264 cal), the .260 Remington was created. It fit the same short-action [receivers] that fit .308 Win, .243 Win, 7mm-08 Rem, etc. You can expect velocities of 2600-2700 fps with 140gr bullets in the 260 .Remington.
[Editor’s Note: In the .260 Rem, try the Lapua 120gr Scenar-Ls and/or Berger 130gr VLDs for great accuracy and impressive speeds well over 2900 fps.]
6.5mm x 55 Swedish Mauser – This was the cartridge that started the 6.5mm craze in the USA. It is famous for having mild recoil, deadly lethality on even the biggest game animals, and superb accuracy potential. Original ballistics were in the 2500 fps range with 140gr bullets. Nowadays handloaders get 2600-2700+ fps.
[Editor’s Note: Tor from Scandinavia offers this bit of 6.5x55mm history: “Contrary to common belief, the 6.5×55 was not developed by Mauser, but was constructed by a joint Norwegian and Swedish military commission in 1891 and introduced as the standard military cartridge in both countries in 1894. Sweden chose to use the cartridge in a Mauser-based rifle, while Norway used the cartridge in the Krag rifles. This led to two different cartridges the 6.5×55 Krag and 6.5×55 Mauser — the only real difference being safe operating pressure.”]
6.5-284 Norma — This comes from necking the .284 Winchester down to .264 caliber. Norma standardized it for commercial ammo sales. The 6.5mm-284 was very popular for F-Class competition and High Power at 1,000 yards. However, many F-Class competitors have switched to the straight .284 Win for improved barrel life. 6.5-284 velocities run 3000-3100+ fps with 140gr bullets.
.264 Winchester Magnum – Developed by Winchester back in 1959, the .264 Win Mag never really caught on and may have delayed the ultimate acceptance of 6.5mm cartridges by US shooters (in my opinion). It missed the whole point and original advantage of 6.5 mm cartridges.
The Original 6.5mm Advantage
The special needs of long-range competition have skewed things a little. However the original advantages of 6.5mm cartridges — how deadly the 6.5mms are on game animals, how little recoil they produce, and how easy they are to shoot well — still hold true today.
Here’s an interesting project — using a second-hand barrel to upgrade an AR15. Our friend Erik Cortina decided to make his AR15, originally chambered in 6.8 SPC, into a 6.5 Grendel. Erik acquired a “pre-owned” 6.5-06 match barrel through our Shooters’ Forum. Erik inspected the barrel with a bore-scope and confirmed it was in good shape after the first few inches (past the chamber). The 6.5-06 barrel had more than enough length, so he trimmed off the chamber end, then contoured the barrel to fit his AR15. This is a smart way to upgrade a gun without spending $350 or more on a brand new barrel.
In the first video, Erik explains the process of converting his 6.8 SPC AR15 into a 6.5 Grendel: “I take the upper completely apart and pull barrel off which will be used to take dimensions for new barrel. The new barrel will be turned from an old competition heavy barrel. All the barrel reaming will be done using JGS reamers. I will also use JGS reamers to make a seating and F/L sizing die.”
In the second video, Erik contours the “pre-owned” barrel to fit his AR. He uses an old bolt-action 6.5-06 competition barrel and cuts it to 17″ long and contours it to fit his AR-15. The barrel is turned down on a manual lathe to .750″ outside diameter for the majority of its length in order to fit the gas system barrel block that is made for a .750″ barrel. After contouring, the barrel will be threaded and chambered.
AccurateShooter.com Forum members often ask: “Is there a reasonably-priced ammo box that fits PPC and BR cases just right?” The answer is yes — check out the 50-round Frankford Arsenal model 512 ammo box. It is offered in transparent blue or smoke gray for $3.49 per box at MidwayUSA (or $3.99 per box at Amazon.com).
The cartridge slots are just the right size for 22BR, 6mmBR, 30BR, 220 Russian, 6 PPC, 6.8 Rem SPC, 6.5 Grendel, and 7.62×39 cartridge cases. Cells are 1.687″ high x 0.392″ square, with a divider height of 0.94″. That will hold BR-type cases securely, and fired brass won’t get jumbled if you tip-over the box.
TECH TIP by Robert Whitley,AR-X Enterprises LLC
Over the years, while working with various AR-15 cartridges that require a larger bolt-face bolt (i.e. bigger than a 5.56 NATO/.223 Rem bolt-face, like those cartridges that use a 6.8 SPC bolt or the bolt face suitable for the 6.5 Grendel-based cartridges), I have found that there is an increased potential for a certain type of jam if a modification to the standard “Mil-Spec”, square-edged ejector is not made.
The original AR-15 square-edged ejector design was made for a much smaller-diameter bolt face and the smaller diameter 5.56 NATO/.223 Rem case, and it works perfectly in that application. However, as people have adapted the AR-15 platform to shoot bigger cartridges, some parts have been modified to accept the larger cartridges (i.e. bigger bolt-face bolts for the 6.8 SPC and the 6.5 Grendel, and different extractors), yet other parts have been all but ignored. One of these “ignored” parts has been the ejector. Most of the larger-bolt-face AR-15 bolts still use the standard “Mil-Spec”, square-edged 5.56 NATO/.223 Rem. ejector. That’s the problem. But there is a simple, reliable fix!
Chamfering AR Ejector for Improved Reliablity with 6mm, 6.5mm and 6.8mm Cartridges
With the larger bolt face and the larger-diameter AR cases, the old-style “Mil-Spec” ejector can cause infrequent but still annoying jams if the ejector is not modified. The jam can occur when a cartridge case feeds up and out of the right side of the magazine, and as it does so, the back of the case must slide across the bolt face and sideways over top of the ejector if it is to center up to the chamber and feed in. If the side of the case catches on the sharp-edged ejector you can get a jam. (See picture above).
Fortunately there is an easy fix for this. One way is to take the ejector out and spin it in a lathe or cordless drill and machine or grind it and round or chamfer the sharp edge. (See picture of rounded ejector next to square edged ejector).
Quick Fix Alternative — Bevel Your Ejector
Another “quick fix” is to leave the ejector in the bolt and chamfer the sharp edge with something like a Dremel tool. (See picture). This fix is easy to do and permanently resolves this potential feeding jam issue. There are no downsides to this modification if done right and I would recommend this modification for the ejectors in all larger bolt-face AR-15 bolts.

Robert Whitley of AR-X Enterprises has a new .30-caliber cartridge for AR-platform rifles. The new 30 ARX is based on the 6.5 Grendel parent case necked-up to .30 caliber. The 30 ARX mag-feeds flawlessly in an AR15, while offering excellent accuracy, good velocity, and serious knock-down power. Compared to a 300 AAC Blackout (300 BLK), the new 30 ARX holds much more powder so it can push bullets faster and harder. Whitley’s 30 ARX boasts 57% more case capacity than a 300 Blackout. As a result, the 30 ARX outperforms the 300 BLK by a large margin. In a 20″-barreled AR, the 30 ARX can drive a 125gr bullet at 2500+ fps, or launch a heavier 150gr bullet at 2400+ fps:
30 ARX Loads
H4198, CCI BR4 Primers,
Necked-up Lapua 6.5 Grendel Brass:
2419 FPS: 28.0 gr. H4198, Nosler 125gr Ballistic Tip Hunting Bullet (2.260″ OAL)
2517 FPS: 29.0 gr. H4198, Nosler 125gr Ballistic Tip Hunting Bullet (2.260″ OAL)
2363 FPS: 28.0 gr. H4198, Sierra 150gr BT Hunting Bullet (2.240″ OAL)
2441 FPS: 29.0 gr. H4198, Sierra 150gr BT Hunting Bullet (2.240″ OAL)
Robert Whitley explains the advantanges of the 30 ARX for AR-platform rifles: “The 30 ARX is a cartridge designed from the get-go for use in an AR-15. The case length and chamber design of the 30 ARX are optimal. The case allows the use of many of the favorite .30-cal bullets, magazine fed out of an AR-15 and backed by some real power. Brass is easy to make with a simple necking-up process. Neck it up, load it and go shoot. Good 6.5 Grendel brass is readily available, and we have 30 ARX dies available.”
Watch One-Step Process for Forming 30 ARX Case from 6.5 Grendel Brass
With the ability of Lapua 6.5 Grendel brass to handle stout loads, the 30 ARX cartridge delivers 30-30 Winchester-class performance, from the modern, semi-auto AR-15 platform. The 30 ARX cartridge has sufficient case capacity to push popular .30-cal bullets fast and accurately even at moderate chamber pressures. The case has approximately 38 grains water capacity. With its 57% greater capacity than a 300 Blackout, the 30 ARX is a more versatile, more powerful hunting cartridge (at least when loaded to supersonic speeds). With 150gr bullets running in the 2500 fps range, the 30 ARX offers impressive knockdown power in a cartridge that fits an AR-15 magazine.
30 ARX Cartridge OAL mag-feeds perfectly with a variety of .30-cal bullets.
Longer, heavier long-range bullets (with longer COAL) can be single-loaded.
Lapua 6.5 Grendel brass is excellent, strong brass, that is readily available.
AR-X Enterprises now offers die sets for the 30 ARX.
The neck up process is very easy. Simply lube the inside of the necks of 6.5 Grendel brass, run the brass through your re-size die (with .30 Cal expander in place).
Works well with a lot of commonly available powders such as: Hodgdon 4198, Vihtavouri N130, Accurate LT-32, Accurate AA1680.
6.5mm Creedmoor – Developed by Hornady and Creedmoor Sports, the 6.5mm Creedmoor is designed for efficiency and function. Its shape reaches high velocities while maintaining standard .308 Winchester pressures and its overall length fits well with .308 Win length magazines. You can expect velocities of 2600-2700+ fps with 140gr bullets.
