Our friend Dennis Santiago has a reptilian rig in his arsenal. It’s actually an Eliseo R1 single-shot tubegun chambered in .284 Winchester. The eye-catching aspect of Santiago’s .284 bolt-gun is the snakeskin dip job on the exterior. This really creates a distinctive look. Dennis tells us: “It was Gary Eliseo’s idea to try a water-transfer printing finish for this rifle. There are many patterns to choose from — this is the WTP-260 Snakeskin Illusion-Fall Copper from WaterTransferPrinting.com. For a single shot LR gun, I figured something on the bright side would be interesting and pick up less heat from the sun in the summer.”

Dennis uses this eye-catching rifle in prone matches, where a single shot works fine. He says: “Underneath the hood, it’s a Rem 700 Long Action, chambered in .284 Win. Yes it’s a single shot! I don’t need anything else for a prone gun. Nothing to get in the way of building the perfect position.”

Dennis says: “Length of pull, offset and cast initially set the same as my similar RTS .308. My gun, my body dimensions.”

R1 Testing with Advanced Electronic Shot-Plotting System
Now that winter is here, Dennis plans to do some serious load development with this rifle: “I acquired a new ShotMarker electronic target system. I’ll be using that to test a variety of powders and bullets.” Dennis has previously loaded his .284 Win R1 with Hodgdon H4831 powder, but he hopes to test alternatives from Alliant and IMR as well. There are many interesting 7mm bullet options, such as Sierra’s impressive, factory-pointed 183gr MatchKing with 0.707 G1 BC, and Berger’s new 184gr F-Open Target Hybrid with 0.695 G1 BC.

The ShotMarker is a unique 8-sensor acoustic electronic target that instantly plots shot locations and transmits the data via WiFi to a mobile device. Dennis is eager to try his new Shot-Marker. The system can measure group size, velocity, and SD. The Shot-Marker App can then store your strings for later review, add notes to the target, and export data to spreadsheets.

A FFP 6-24x50mm Sightron Rides on Top
The optic is a Sightron 6-24x50mm, FFP MOA-2. Dennis reports: “I looked at many scopes (within my determined price range), and this is the one that had the best combination of features for for this gun’s particular application. The sight line sits about 3 inches above bore line on these guns. It’s been leveled, bore-sighted and pre-dialed for a 200-yard estimated zero for the ammo I plan to use. Those are Gen II A.R.M.S. rings. Super easy to tailor to different rail widths. Same rock-steady steel performance.”

New 7mm 184gr F-Open Hybrid Target Bullet from Berger

Berger F-Open Hybrid Target Bullet Bryan Litz Applied Ballistics

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.

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.”
