Here is the view from 9500 feet ASL. The SRS in 7mm Rem SAUM almost outran the Swarovski laser…
7mm RSAUM in a bolt-action bullpup? Yes it works. A talented shooter, who calls himself “ColdboreMiracle” in social media, has a Desert Tech SRS-A1 rifle chambered for the 7mm RSAUM, and it hammers. The 7mm Remington SAUM (Short Action Ultra Magnum) is popular with F-Open competition shooters. It can also work well for long-range hunting and tactical tasks. Learn more about the 7mm Remington SAUM in our 7mm Cartridge Guide.
ColdboreMiracle owns the SRS-A1 “covert” model, which has a shorter handguard than the standard SRS-A1 model shown below. Desert Tech now offers an SRS-A2 model which has an M-LOK handguard and some refinements to the chassis.
Here is a detailed video review of a Desert Tech SRS chambered in .308 Win. You can see a close-up of a 100-yard 5-shot group at time-mark 6:25:
Here is a review of the newer SRS-A2 Covert (shorter model), after 1000 rounds. The reviewer believe the SRS bullpup’s shorter length offers some advantages for precision shooters:
ColdboreMiracle says the bullpup design has many advantages: “The Stealth Recon Scout (SRS) rifle from Desert Tech is a bullpup-configured precision rifle with a shorter length than many carbines. The SRS has a multitude of barrel options that can be swapped in under a minute — all of them come with a 1/2-MOA accuracy guarantee and return to zero. The SRS’s bullpup design puts the rifle’s COG closer to the shoulder, making the rifle balance better off-hand. The straight-line geometry of the SRS makes recoil seem lighter, and barrel hop is reduced, allowing the shooter to stay on target better. It takes a little getting used to, when converting from a traditionally-configured bolt gun. But once you do, you won’t go back.” To learn more about this rifle (and other Desert Tech arms), visit ColdboreMiracle’s Facebook Page and YouTube Channel.
The 7mm RSAUM — Why It Was Chosen for this SRS
ColdboreMiracle explains how he selected the 7mm Rem SAUM chambering for his Desert Tech SRS Bullpup: “I just did a comparison between barrel life, velocity, brass, etc. and came to the SAUM. I can tell you this, if you go with one for your SRS, make sure you use long bullets like the 183 or 195, and seat them long. That will aid in smooth cycling.”
Mr. ColdboreMiracle tested the new generation 183gr Sierra MatchKings (item # 1983). These impressive projectiles are “tipped” at the factory. Claimed G1 BC is a lofty 0.707 (at 2300 fps and above). We have heard other reports that these bullets “hold waterline” exceptionally well at 1000 yards. That indicates the bullet-to-bullet BC is very consistent. No doubt the factory uniforming/pointing of the bullet tips helps in that regard.
As you can see, these 183-grainers shoot well in ColdboreMiracle’s SRS rifle. Here are five shots at 100 yards. That’s very impressive for a tactical-style rifle shot from a field-type bipod.
ColdboreMiracle says: “This is the only reason I need to shoot Sierra bullets. On the right (above) you can see the results of the 183gr SMK from my 7mm SAUM. Five shots at 100. A huge thanks to Mark at Short Action Customs, LLC for [chambering this barrel] for my Desert Tech SRS.”
7mm Remington SAUM — Key Considerations
In some respects, the 7mm SAUM cartridge may be better than the 7mm WSM. The 7mm SAUM holds less powder — but that’s a good thing, since the capacity is more than adequate to do the job. You can drive the 180s at 3000 fps with a SAUM using less powder than with a WSM. Additionally, the SAUM case has a slightly longer neck. This gives you greater flexibility in bullet seating. With a long neck you can set the throat so the long 180+ graing bullets are above the neck shoulder junction, yet you can still seat shorter hunting bullets close to the lands. Additionally, long case necks, some believe, cause less throat erosion than shorter necks. That’s not “hard science” but it is certainly a view shared by many experienced shooters. The long neck is one reason many varminters favor the 6mm Remington over the .243 Winchester.
7mm RSAUM Is More Efficient than 7mm WSM
7mm RSAUM shooter Steven Ikeeda tells us: “I decided that some type of 7mm was the ticket for doing well at 1000-yard matches, especially if one could drive the high-BC bullets at 2900+ fps. Looking over various 7mm cartridges that could produce those velocities (and didn’t require case-forming), I was impressed by the 7mm SAUM and the 7mm WSM. According to the load manuals, the 7mm WSM offered a bit more velocity than the 7mm SAUM. However, to achieve its small velocity advantage, the larger 7mm WSM had to burn 7-10% more powder than the 7mm SAUM. (The 7mm WSM has 81.0 grains of capacity vs. 73.6 grains for the 7mm SAUM.) The SAUM is a very efficient case. It looks like a 6.5×47 Lapua on steroids.”

Shooter Profile by Des Parr, UK
We have a new European F-Open Champion: Paul Hill from the UK. If he looks familiar, it’s because Paul appeared here 12 months ago when he set a new F-Open record score of 100-17X at 900 yards at last year’s European Championships. There are some factors which make Paul’s victory all the more significant. First, he didn’t employ a top gunsmith to do his work — he’s a real working-class here who did it all himself. To keep costs down he taught himself to do all his own machining and bedding. Paul acquired a lathe, learned how to run it, and then carefully did all his own chambering and fitting. He then taught himself how to bed the rifle too. You have to admire a man who teaches himself how to build Championship-winning rifles.
Another unusual factor is Paul’s choice of components. Paul used the Lapua Scenar 180-grain bullet, the same bullet used to set his 2016 record. The 180gr Scenar is a fairly “old-fashioned” shape, but Paul points them using a “shooting shed” pointing tool. For seating, he uses his own home-made die with a Wilson top. Whatever the Lapuas may lack in BC, they more than compensate for in consistency, and that’s the key to success. As an aside, they compare very favourably in tests on the Juenke ICC machine, indicating that they’re very well made indeed.
Paul Hill Equipment List
Paul shot in the F-Open class firing the 7mm RSAUM cartridge, a short magnum. He ran a 30″ Krieger 1:9″-twist barrel mated to a Barnard Model P action bedded in a Joe West laminated stock. His pushed those Lapu8a Scenar with the relatively new Reload Swiss RS70 powder. Paul rates this RS70 propellant very highly. It may be unfamiliar to shooters in the USA, but RS70 is REACH compliant and is likely to become more popular when many other powders are forbidden from the EU next year. Paul is also a big fan of the Russian KVB-7 primer, a very mild and consistent primer — marketed under “Wolf” in the USA.
It is not just about having the right equipment though, it is also all about the application of skills and techniques and Paul was very keen to acknowledge his debt of thanks to Erik Cortina for his reloading techniques and Brian Litz for his writings on range mind set and diet. There is another, until now, secret factor that may have helped Paul. He is an Apiarist (bee-keeper) and he swears by the beneficial effects of his daily honey on toast. Who knows? Perhaps he’s on to something — nothing sells like success, so Paul’s honey sales may take off now just like his shooting career.
Here’s a good video showing F-Class Shooters at Bisley (FieldSports Channel 2015)
2016 Wasn’t So Bad Either
Paul Hill’s 2017 Championship win followed an impressive performance last year. At the 2016 European F-Class Championships at the Bisley Ranges, Paul set a record score at 900 yards: 100-17V! That’s 17 shots placed in a five-inch circle the size of a CD (compact disc) at over half a mile. [NOTE: At Bisley, the maximum score is FIVE points, not ten points. So the maximum score for 20 shots is 100. Also what Americans call an “X” is called a “V” at Bisley.]
Record Set with Slower Pair Firing Method
The style of shooting in Great Britain is pair-firing. Under this procedure, each of two competitors shoots alternately, taking turns from shot to shot. Each shooter has 45 seconds to take his shot. Allowing for the target pullers to do their jobs, this means that each shot can take up to one minute. As Paul was pair firing, he had to concentrate for up to 40 minutes to get all 20 shots off! You can imagine how many times the wind changed course in those 40 minutes –pick-ups, let-offs, changes of angle and direction. Paul had to counter each change and still managed to put 17 shots in that 5-inch circle!

F-Open shooter Kenny Adams has enjoyed a spectacular 2013-14 season. Over the past 12 months “King Kenny” enjoyed a string of successes that established Adams as the man to beat in the ultra-competitive F-Open ranks. After finishing second at the 2013 F-Class Nationals, Kenny won the 2013 World Championship. He then won a series of regional matches heading into the 2014 National Championship. There he finished on the podium with a 3rd Place finish in the individual competition. He then earned gold as a member of the winning 4-man F-Open squad, Team Grizzly. We don’t think any other F-Open pilot has put together a stronger season.
Kenny attributes his success to great team-mates, great equipment, and great ammo. He’s a huge fan of Berger’s 7mm hybrid bullets: “The [Berger] 7mm 180 hybrids have made load testing much easier, and needless to say, raised my scores considerably!” Kenny also gave credit to his gunsmith: “I want to thank my gunsmith, Stick Starks from S&S — he got me going in this thing in the right direction four and a half years ago. Working with Stick has probably shaved a couple of YEARS off my learning curve.” Kenny’s world-championship rifle features a Panda F-Class action, Krieger barrel, and a Robertson F-Class stock. Kenny likes this combo so much he actually owns four complete red rifles with similar configurations. Check them out:
Kenny pushes those 180gr hybrids with the 7mm Remington SAUM (RSAUM) cartridge. A “new-generation” magnum, the RSAUM resembles a 6mm BR Norma on steroids. It has the same short, fat appearance, just scaled up — way up. This gives the 7mm RSAU the capacity to drive the big Berger 180-grainers at optimal velocities. The image below shows the older Berger 180gr VLD. Kenny shoots the newer 180gr Hybrid. They are both very, very accurate.
Banner Year for King Kenny
Pictured above is Kenny Adams holding his 1st Place Plaque from the 2013 F-Class World Championship. To the right, Ken (with fellow Team Grizzly members) is pictured at the 2014 F-Class Nationals accepting the Berger Trophy for the First Place F-Open 4-Man Team.
Below are Kenny Adams’s major shooting accomplishments from the past 12 months:
2013 – F-Class Nationals – 2nd Place F-Open.
2013 – F-Class World Championship – 1st Place F-Open.
2013 – Christmas Match in Florida – 1st Place F-Open.
2014 – Southwest Nationals – 1st Place F-Open 4-Man Team Grizzly (Set National record).
2014 – Orange Blossom Regional – 1st Place F-Open.
2014 – Sinclair East Coast Fullbore Nationals – 1st Place F-Open and set new Fullbore national record.
2014 – Mid West Palma – 1st Place F-Open 1200-yard match and set 1200-yard record.
2014 – F-Class Nationals – 3rd Place F-Open.
2014 – F-Class Nationals – 1st Place F-Open 4-Man Team Grizzly.
Kenny’s World-Beating 7mm RSAUM Load
For his 7mm RSAUMs Kenny loads Hodgdon H4350 powder and Federal 215m primers into Nosler or Norma RSAUM brass. In the RSAUM he runs Berger 180gr Hybrid bullets seated “just touching” the lands. Kenny is very precise with his charge weights. Using a Sartorius Magnetic Force Restoration scale, Kenny tries to hold his powder charges to within 1-2 kernels charge-weight consistency.
When you get it all correct, when every phase of the reloading process has been carried out perfectly, then you have rounds that can set records and win world titles. So what does championship-grade ammo look like? Take a look at the photo above. This is the 7mm RSAUM ammunition used by Kenny Adams at the 2014 Berger Southwest Nationals (SWN). Kenny is the 2013 F-Class World Champion.

For top-level competitors, hand-loading is truly the “relentless pursuit of perfection”. To build ammo capable of winning major long-range matches, you’ll need the best tools — and an almost obsessive attention to detail. The bullets must be ultra-consistent, powder charge weights must be “dead on”, seating depths (as measured from base of case to ogive) must be precise, and neck-tension must be the same for every round that goes in the chamber.

American Kenny Adams is the new F-Open World Champion, winning the individual title last week at Raton, New Mexico. ‘King Kenny’ rose to the top through with skill, countless days of practice, and great determination. He put in the trigger time, including many long days at Raton. But when we cornered Kenny after his win at the Worlds he was quick to give credit to his gunsmith, Stick Starks of S&S Precision Rifles in Texas.
Kenny told us: “I want to thank my gunsmith, Stick Starks from S&S — he got me going in this thing in the right direction four and a half years ago. Working with Stick has probably shaved a couple of YEARS off my learning curve.” Kenny’s world-beating rifle features a Panda F-Class action placed in a Robertson F-Class stock. The Krieger barrel is chambered for the 7mm RSAUM.
Kenny Has Four Red F-Class Rifles All By S&S
What’s interesting is that Stick Starks made Kenny three other F-Class rigs, all with red Robertson stocks and Panda F-Class actions. So, counting the championship 7mm RSAUM, Kenny owns a fleet of four fire-engine-red F-Class rigs, all built by Stick at S&S. These three other red rifles were originally chambered in 6.5-284, 6mmBR, and 6.5×47, but Kenny switches barrels (and chamberings) to suit the venue and course of fire. In Raton, Kenny had two (2) of the red rifles chambered in 7mm RSAUM and two (2) chambered for the .284 Winchester. However, in the Individual World Championship he shot just one rifle, a 7mm RSAUM (shown below). He used the second 7mm RSAUM-chambered rifle in the F-Open Team Championship. This second RSAUM (used for team shooting) is the one pictured above, but his other RSAUM is identical in all respects. He did not shoot either .284 Win during the Worlds.
Kenny’s World-Beating 7mm RSAUM Load
For his 7mm RSAUMs Kenny loads Hodgdon H4350 powder and Federal 215m primers into Nosler or Norma RSAUM brass. In the RSAUM he runs Berger 180gr Hybrid bullets seated “just touching” the lands. For his .284 Winchester-chambered rifles he loads necked-up Lapua 6.5-284 brass with 180gr Hybrids pushed by H4831sc powder and Federal 210m primers. Interestingly, he is very precise with his charge weights. Using a Sartorius Magnetic Force Restoration scale, Kenny tries to hold his powder charges to within 1-2 kernels charge-weight consistency.
While Kenny praised S&S for building great rifles, Stick is quick to say that Kenny deserves the credit: “He’s the man that pulled the trigger. He’s the man that beat the world. You can’t believe how dedicated Kenny is to his sport. He spends so much time shooting and practicing — true dedication. Kenny hung in there, never gave up, did the best a man can hope to do. Yeah you have to have good equipment, but you do have to have dedication in this sport. Buy the best equipment you can and the rest is up to you — learning how to read conditions. That’s all there is to it.”
S&S Can Build You a ‘Kenny Clone’ for $3800.00
By the way, if you want a gun just like Kenny’s, Stick told us: “I’ve got barrels, Panda F-Class actions, and I have one last Robertson F-Class stock left. Just one — these aren’t made any more you know. A complete build, with barrel of your choosing and Jewell trigger, will be about $3800.00.”
S&S Precision Rifles is a leading gunsmithing operation based in Argyle, Texas. Stick Starks and the crew at S&S build very accurate rifles, that also exhibit superb craftsmanship. While S&S built a championship-winning F-Open gun for Kenny, they can also built short-range benchrest rigs, as well as varmint and hunting rifles — all with hallmark S&S quality. S&S can handle every aspect of gunsmithing — chambering, bedding, even stock-painting.
In the video above, the folks at S&S put together some tack-drivers for their customers. There are some nice glimpses of bedding work, and barrel finishing. Watch carefully — at the 40-second mark you’ll see a sub-1/4″, 10-shot group that S&S co-owner “Stick” Starks shot at 200 yards with his 6.5×47 Lapua rifle. That’s serious accuracy. Half-way through the video, Stick offers advice for shooters looking for a super-accurate fun gun for club shoots: “If you want to shoot [at] 100 and 200 yards, I’d get me a 6BR or a 30 BR. It would be the most fun gun you ever had… and the barrel will probably last three or four thousand rounds.” If you want a gun to shoot at primarily 500-600 yards, Stick recommends the 6.5×47 Lapua chambering: “Run it with the Berger 130s and Hodgdon H4350 powder. That H4350 works great with the 130 Bergers.”

We are coming to the end of another fall hunting season. If you are pursuing big game, such as Elk in the Rockies, you want a powerful cartridge that is also highly accurate. We like the 7mm for big game hunting as there are a wide variety of options — from the 7mm-08 up to the very large 7mm magnums. And Hornady’s new 7 PRC has quickly earned a following among hunters. In today’s Saturday Movie Showcase, we feature seven videos covering a wide selection of 7mm cartridge types including: 7mm-08 Rem, 7×57 Mauser, 7mm PRC, 7mm WSM, 7mm SAUM (aka RSAUM), 7mm Rem Mag, and 28 Nosler.
7mm PRC in Custom Rifle
The 7mm PRC was created by Hornady as part of the PRC series which includes the 6.5 PRC and 300 PRC. With a modern, non-belted magnum case design the 7mm PRC offers excellent power with good ballistics. The 7mm PRC can drive high-BC 175 grain bullets at 3000 FPS, making it very effective at putting down large game. This Precision Rifle Network video features a high-end custom 7mm PRC rifle built with a Terminus Zeus action, 29″ barrel, Grayboe stock, Triggertech trigger and Athlon scope. This 7mm PRC rig shows impressive accuracy.
7mm Remington Magnum vs. 7mm PRC
In this video, UltimateReloader’s Gavin Gear tests the classic belted 7mm Remington Magnum vs. the relatively new 7mm PRC. Testing is done with two hunting-type rifles shot from bipod. Gavin notes that both cartridges shoot very well, with impressive down-range energy. But he concludes that the non-belted 7mm PRC does have some advantages.
7mm Remington Magnum SAKO S20
This rifle review video features real world testing of a SAKO S20 hunting rig chambered for the 7mm Remington Magnum cartridge. The SAKO S20 is offered with multiple stock types. Here the thumbhole Hunter version with slim fore-end is featured. The testers observe that the 7mm Rem Mag factory ammo shoots very well, making the cartridge a good choice for large game.
Most Popular 7mm Cartridges
This Ron Spomer Outdoors video covers a variety of the most popular 7mm cartridges. The video covers 7mm cartridge history, ballistics, and recommendations for hunting use. Starting at the 6:45 time-mark there is a detailed ballistics comparison of the Hornady 175gr ELD-X (Extremely Low Drag eXpanding) bullet in three different chamberings: 7×57 Mauser, 7mm-08 Rem, and 7mm Remington Magnum.
7mm SAUM vs. 7mm WSM
This 17-minute video compares two modern 7mm short magnum cartridges — the 7mm SAUM (Short Action Ultra Magnum) and the 7mm WSM (Winchester Short Magnum). Both these cartridges have been adapted for F-Class Open Division use over the years. In this video, factory ammo for both cartridge types was tested with a modern chassis rifle shot prone with bipod.
7mm-08 Remington
The 7mm-08 Rem is a popular cartridge derived from the .308 Winchester necked down to 7mm. In 1980, Remington Arms popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles. Of cartridges derived from the original .308 Win, the 7mm-08 is the second most popular after the .243 Winchester.
Other than neck diameter, the 7mm-08 is virtually the same dimensionally as the .308 Win. But when you compare heavy bullets, grain for grain, the 7mm-08 offers better ballistics. Thus a 168-grainer fired from a 7mm-08 has less drop and less windage than a 168gr bullet fired from a .308 Win. The 7mm-08 enjoys most of the advantages of the .308 (inherent accuracy, long barrel life, great terminal performance) while offering better ballistics grain for grain. These qualities make the 7mm-08 a very popular deer-hunting round.
7mm Multi-Cartridge Comparison
Do you want a 7mm rifle, but haven’t chosen a cartridge yet? This lengthy 30-minute Ron Spomer video looks at a host of 7mm cartridge types. There is special emphasis with comparison data for the 7mm-08, 7mm Rem Magnum, and 28 Nosler (see 19:40 time-mark). Ron explains how to efficiently zero a rifle with these 7mm cartridges and how hunters can evaluate Maximum Point Blank Range (MPBR).

November 5th is the final day of the 2023 NRA F-Class National Championships at the Ben Avery shooting facility in Phoenix, Arizona. Along with America’s ace F-Open and F-TR shooters, there are many top foreign shooters at the Nationals, including Sebastian (“Seb”) Lambang, creator of the outstanding SEB Rests and SEB Joystick bipods. For this Fall 2023 event, Seb commissioned a handsome new, state-of-the-art F-Open rifle built by Blake Barrel and Rifle. Above is Seb’s F-Open rifle on the firing line this week at Ben Avery. For full results from the F-Class Nationals, click the link below:
Seb Lambang’s impressive new 7 FCP rig was crafted by Blake Barrel and Rifle using a 7mm, 1:8.5″-twist Blake barrel chambered in 7 FCP fitted to a Borden Accuracy BRMXD action. Mated to the Borden action is a Bix’N Andy Competition Benchrest trigger. On top is a March 10-60x56mm HM scope.
The handsome laminated wood XR stock is made by Cerus Rifleworks. The XR stock boasts a R.A.D. recoil reduction system in the rear, and a metal bag-rider system at the forward end of the stock. The rig employs an adjustable F-Class Products F-Open Barrel Tuner.
Seb Lambang is a talented shooter as well as a great craftsman. On the side of his March X scope it states: “Sebastian Lambang, QRA Queens 2022, F-Open Winner”.
Sebastian Lambang — Founder and Chief Designer of SEB Rests
When he is not competing, Seb works hard producing SEB Front Rests, SEB Neo-X Rests, SEB Mini-X tripod rests, and the class-leading SEB JoyPod-X joystick bipod, favored by F-TR shooters worldwide. Here are products at Seb’s warehouse, getting ready to be shipped out.
About the 7 FCP — New 7mm Cartridge Derived from 6.5 PRC
The 7 FCP was a cartridge designed from the ground up by F-Class Products out of Phoenix, Arizona in the fall of 2022. The developers believe it is the “ultimate cartridge” for the F-Class Open Division competition. F-Class Products notes: “We wanted a cartridge that [had] an efficient case capacity [matching] the 7mm Remington Short Action Ultra Magnum. The 7 RSAUM has proven to be the most winning cartridge in world F-Class competitions and many nationals and finale events. The problem with the RSAUM is brass availability. Remington stopped making brass for the RSAUM years ago and recently Norma has also stopped producing brass for it. The only option now is ADG. While the ADG brand of brass is good, it is quite expensive and also is only run in short runs and is hardly ever available.”
So the 7 FCP was developed from the 6.5 PRC, which has high-quality Lapua brass available. The 7 FCP was designed to shoot the 180 grain Berger Hybrid bullet at 2960 FPS out of a 30″ barrel without excessive pressure. SEE: 7 FCP Cartridge INFO FAQ Page.

F-Class Products states: “The parent case of the 7 FCP is a 6.5 PRC. The 6.5 PRC is a magnum case that has a head diameter of 0.532″ and has a overall length of 2.020″. It is the same overall length as the 7 RSAUM but with a smaller diameter body. Hence, without improving it, you will get not get the case capacity of a 7 RSAUM case, and therefore you will not get the velocities that the 7 RSAUM produces either.” F-Class Products has compared the capacity of cases commonly used in F-Open competition:
.284 Winchester = 63 grains of water capacity
.284 Shehane = 66.5 grains of water capacity
6.5 PRC = 65 grains of water capacity
7-6.5 PRC = 66.5 grains of water capacity
As you can see by the data above, the 6.5 PRC that is simply necked up to a 7mm does not provide more case capacity than the .284 Shehane. That is why the PRC has the shoulder moved forward.
What Powders Work Well in the 7mm FCP?
F-Class Products has tested many powders with the 7 FCP: “Any powders that work well in a .284 Win, a .284 variant or a 7 RSAUM and/or variant, can work well in the 7 FCP. We have tested many different powders and many show to work excellent. Here is a list of the powders we have tested that work well in our testing and in our customers’ testing:
Hodgdon H4350
Hodgdon H4831
Hodgdon H4831 SC
Alliant Reloder 16
Alliant Reloder 23
Vihtavuori N160
Vihtavuori N550
Vihtavuori N555
This is just a short list of what we believe are the core powders that will burn and work efficiently in the 7 FCP. There are plenty of other powders that also can work, yet they may be temperature sensitive and or not burn efficiently in the case.”
What Velocities Are Optimal?
F-Class products observes: “With the 180 grain Berger bullet we see accuracy from 2920-2980 FPS muzzle velocity. With the 190 grain Hornady A-Tip bullet we see accuracy from 2860-2900 FPS.”
What Twist Rates Do You Recommmend?
F-Class Products recommends a 1:8.5″-twist barrel. An 8-twist can work, yet the accuracy nodes may be narrower than the 8.5 twist. A 9-twist barrel can also work if you are shooting a 184 grain bullet or less. These twist rates are recommended for lead cored bullets. If you are planning on shooting a solid copper bullet, consult the bullet manufacture for recommended twist rates for that particular bullet.
What Is the Parent Case?
The parent case of the 7 FCP is a 6.5 PRC. The 6.5 PRC is a magnum case that has a head diameter of 0.532″ and has a overall length of 2.020″. It is the same overall length as the 7 RSAUM but with a smaller diameter body, hence without improving it, you will get not get the case capacity of a 7 RSAUM case, and therefore you will not get the velocities that the 7 RSAUM produces either.

Just in time for the Berger SW Nationals, Berger has released a class-leading new 7mm bullet — the 190 Grain Long Range Hybrid Target (LRHT). The new 190-grainer boasts a “jump-tolerant” hybrid ogive profile along with formed meplat (bullet tip) for more consistent Ballistic Coefficient (BC). In fact, with its new MRT (Meplat Reduction Technology) nose, Doppler Radar testing confirms less than 1% BC variation from bullet to bullet. While a high BC is of course desirable for competitive shooting, shot-to-shot BC consistency is most critical when engaging targets to 600 yards and beyond. The new 7mm 190gr LRHT’s BC numbers are very impressive: 0.751 G1 and 0.384 G7.
Designed for F-Open competition, the 7mm 190gr LRHTs are optimized for cartridges such as .284 Winchester, 7mm WSM, 7mm SAUM, and 7mm Remington Magnum among others.
No you don’t need a new barrel to shoot the 190s. If you are running Berger 184s in a 1:9″ or faster twist you should be fine. Berger states: “The 190gr LRHT is complementary to the industry-leading Berger 184gr F-Open Target bullet with an identical stability factor and improved ballistics when launched from 1:9″-twist barrels.”
Meplat Reduction Technology for More Consistent BCs
Utilizing advanced and proprietary manufacturing processes, Berger’s innovative Meplat Reduction Technology (MRT) applies controlled pressure along the nose of each LRHT bullet. Berger states this delivers ” a homogeneous and repeatable profile for the industry’s most consistent Ballistic Coefficients”.
“With improved MRT consistency contributing to its superior ballistic coefficient and form factor, the 190 is one of our highest performance projectiles to date. They provide minimal dispersion and more hits on target for F-Open competitors, long range shooters and larger capacity 7mm enthusiasts.” said Garett Stoddard, Berger’s Lead Production Engineer.
The new Berger 7mm 190 Grain Long Range Hybrid Target Bullets are shipping now to Berger authorized retailers.

There is a new, ultra-high performance 7mm projectile for F-Open and long-range competitors. Berger has introduced a new 184gr F-Open Hybrid Target bullet, which will be the official 7mm bullet of the U.S. F-Open Rifle Team. The new 184-grainer is an advancement over previous 7mm match bullets. As you can see above, the new bullet is longer and sleeker than Berger’s existing 180gr Hybrid Target bullet. The new design gives the 184gr F-Open Hybrid impressive 0.695 G1 and 0.356 G7 Ballistic Coefficients. Compare that to 0.680 G1 and 0.349 G7 for Berger’s 180gr Target Hybrid bullet.
Bryan Litz of Applied Ballistics designed the new 184gr F-Open Hybrid to be slightly heavier, slightly longer, and have a more aggressive ogive shape. This gives the new 184-grainer a ballistic advantage over Berger’s existing 7mm 180gr Hybrid and VLD Target bullet designs. This bullet complements the .30 Cal 200.20X Hybrid Target bullet that was released last year in collaboration with the U.S. F-TR Rifle Team. As with that 200.20X bullet, for the new 184gr F-Open Hybrid, Berger took a successful, existing design and optimized the ballistic profile to make it even better. Along with .284 Win and 7mm SAUM used by F-Open shooters, this bullet should work well in a variety of 7mm cartridges.
New 184gr Hybrid Bullet Tested Extensively by U.S. F-Open Rifle Team
The U.S. F-Open Rifle Team tested the 184gr F-Open Hybrids thoroughly to ensure that they performed as well on target as they did in theory. The results were very positive, and this bullet has been adopted as the official 7mm bullet for the U.S. F-Open team. “The United States Rifle Team 2021 F-Open is extremely excited about the release of the new Berger 184gr F-Open Hybrid. Many members have tested the prototype bullets with outstanding success,” says Dan Bramley, Team Captain.
Note: On the Berger website, Berger lists a recommended 1:8″-twist rate for this new bullet. However, in its June 25, 2018 product announcement, Berger states the Minimum Twist Rate is 1:9″. MSRP is $61.99 per 100-ct box, Berger Part #28408. Grafs.com price is $54.99/box.
Berger says the bullet, which should be available very soon, will work in a variety of 7mm cartridges including: 7mm-08 Rem, .284 Win (and .284 IMP), 7mm SAUM, 7mm RUM, and 7mm Rem Mag.
Berger Supports U.S. F-Open Team — $1.00 Per Box
Berger states: “F-Class is one of the fastest growing precision rifle shooting disciplines, requiring the very best precision and accuracy to compete at the top levels. Berger has always been dedicated to making the very best bullets for our shooters. To help support the U.S. F-Open Team, Berger Bullets will donate $1.00 for every box of 7mm 184gr F-Open Hybrid bullets sold towards U.S. Team expenses for the upcoming 2021 F-Class World Championships in South Africa.”

The F-Class World Championships (FCWC) in Canada are just one week away. This August 11-17, the world’s top F-Class shooters will gather at the Connaught Ranges outside Ottawa, Ontario. The vast majority of F-Open shooters will be running some kind of 7mm (.284 Caliber) cartridge, with the .284 Winchester, .284 Win Improveds, and 7mm RSAUMs being popular.
For those of you who plan to compete but who haven’t loaded your ammo yet, you may want to consider a very good 7mm match bullet from Sierra, 183 grain MatchKing (item #1983). We have found the 183gr MK, which comes “pointed” from the factory, to be very consistent in weight and base-to ogive measurement. Top F-Open shooters have told us that these bullets shoot exceptionally well, with minimal vertical dispersion at 1000. “Holding waterline” at long range is a reliable indicator that the BC is very uniform from bullet to bullet.
Sierra’s popular 7mm 183 grain MatchKing boasts an impressive 0.707 G1 Ballistic Coefficient (BC) at 2300+ fps. These bullets also have very consistent bullet-to-bullet BC, thanks to very uniform jackets and the tips being “pointed” at the factory. Sierra explains: “A final meplat-reducing operation (pointing) provides an increased ballistic coefficient for optimal wind resistance and velocity retention.”
Insight Into Sierra’s New 7mm MatchKing® by Sierra Product Development Manager Mark Walker
In late 2015, Sierra introduced a new 7mm MatchKing® bullet with a different type of ogive. As part of the introduction, I had the opportunity to use them at the F-Class Nationals held in Phoenix with very good results. While at the match, several people had questions about what exactly was different about the ogive on this bullet as opposed to our tried and true blended tangent ogive. So with that in mind, hopefully this blog will answer those questions.
In the past, Sierra has typically used a tangent radius ogive design on our MatchKing® bullets. This is one of the most forgiving ogive designs due to its ability to shoot extremely accurately when jumped, as well as, jammed into the rifling. On rare occasions, some of our MatchKing® bullets have used a secant ogive due to design constraints. However, this ogive is much more sensitive to changes in seating depth than the tangent ogive so we tend to shy away from it. When we decided to work on this new bullet, we wanted to see if we could improve on the accuracy of even our best shooting tangent ogive bullets.
One of the main factors of what makes an accurate shooting bullet is how it aligns itself with the bore when fired. If a bullet is slightly crooked when entering the bore, it will cause inaccuracy on the target. We set out trying to think of ways to make sure that the bullet has no choice but to align itself with the bore perfectly.
The first part of the barrel to encounter the bullet is the leade in the chamber. The leade is an angle that is cut into the leading edge of the rifling which helps to guide the bullet into the bore. To illustrate how current bullets fit into the leade, picture a cone (leade) with a ball (bullet) sitting inside it. The ball can be rotated in all directions and the cone cannot force the ball to orientate itself in any particular direction. When a bullet with a radius encounters the leade, it behaves in a similar way. Now this of course is a very simple example and of course advanced shooters use tight necks and brass that is perfectly formed to the chamber to make sure the bullet is aligned as perfect as possible. However, there is always a small element of misalignment that is possible even with all this precise preparation.
This brings us to the ogive on the new 7mm MatchKing®. We thought instead of using the typical ogive radius that can allow slight misalignment, why not use the same straight angle that is used in the chamber leade on the bullet ogive to force itself to always align with the bore? Imagine the same cone as above (leade) with an identical cone (bullet) sitting inside of it. The cone inside has no choice but to align itself perfectly with the cone that it is sitting in every time. With that in mind, we designed the area of the bullet which contacts the leade in front of the bearing surface using a straight 1 1/2 degree angle instead of the typical radius. Once past that area, we use a traditional high caliber ogive radius to provide a very sleek, high BC bullet.
I hope that explains our thought process behind this new bullet. In our testing, it is one of the most forgiving high-BC bullets we have ever made.

In some respects, the 7mm SAUM cartridge may be better than the 7mm WSM. The 7mm SAUM holds less powder — but that’s a good thing, since the capacity is more than adequate to do the job. You can drive the 180s at 3000 fps with a SAUM using less powder than with a WSM. Additionally, the SAUM case has a slightly longer neck. This gives you greater flexibility in bullet seating. With a long neck you can set the throat so the long 180+ graing bullets are above the neck shoulder junction, yet you can still seat shorter hunting bullets close to the lands. Additionally, long case necks, some believe, cause less throat erosion than shorter necks. That’s not “hard science” but it is certainly a view shared by many experienced shooters. The long neck is one reason many varminters favor the 6mm Remington over the .243 Winchester.
F-Open shooter Kenny Adams has enjoyed a spectacular 2013-14 season. Over the past 12 months “King Kenny” enjoyed a string of successes that established Adams as the man to beat in the ultra-competitive F-Open ranks. After finishing second at the 2013 F-Class Nationals, Kenny won the 2013 World Championship. He then won a series of regional matches heading into the 2014 National Championship. There he finished on the podium with a 3rd Place finish in the individual competition. He then earned gold as a member of the winning 4-man F-Open squad, Team Grizzly. We don’t think any other F-Open pilot has put together a stronger season.
Banner Year for King Kenny
For top-level competitors, hand-loading is truly the “relentless pursuit of perfection”. To build ammo capable of winning major long-range matches, you’ll need the best tools — and an almost obsessive attention to detail. The bullets must be ultra-consistent, powder charge weights must be “dead on”, seating depths (as measured from base of case to ogive) must be precise, and neck-tension must be the same for every round that goes in the chamber.
The 7mm-08 Rem is a popular cartridge derived from the .308 Winchester necked down to 7mm. In 1980, Remington Arms popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles. Of cartridges derived from the original .308 Win, the 7mm-08 is the second most popular after the .243 Winchester.
