Sunday GunDay: Dennis Builds an Eliseo Tubegun Palma Rig

Dennis Santiago Eliseo Competition Machine Tubegun Chassis .308 Win Rifle Berger Southwest Nationals

Our friend Dennis Santiago is a talented Service Rifle shooter, who normally competes with an AR shooting the .223 Rem cartridge. Recently he decided to go over to the “dark side”, putting together a Palma (fullbore) rifle chambered for the .308 Winchester. Dennis selected a Competition Machine (Gary Eliseo) R1 Chassis for the project. Here’s Santiago’s account of his “true blue” Palma build…

Palma Rifle Report by Dennis Santiago
“Here’s my new project — a .308 Win Palma rifle with an Eliseo R1 chassis, Rem 700 action (blue-printed with PT&G upgrades), Jewell trigger, Boots Obermeyer 1:11″-twist barrel, and Phoenix sights holding Gehmann apertures. Next comes chassis and sling set-up, initial mechanical zeroing, and load development. Yup, I have a bunch of Peterson small primer .308 brass, Sierra #2156 155gr MKs, and Varget to get started with. I’m told I can drive 155gr pills to stay supersonic to 1K. Should make for an interesting 2020. My goal is to be cozy with this blue beast by the time the Berger Southwest Nationals kick off in February 2020. Hey, you gotta have goals!”

Pinning the Picatinny — For a Super-Solid Mount

One of the key parts of the build, Dennis explains, is mounting the top rail with pins: “Once the rail is aligned using a spin-centered optic, it locks down with three 3/16″ roll pins. That way there is no reliance on screws that can come loose. Above is a photo of the top of the Eliseo tube chassis showing the three, 3/16″ roll pins that unitize the Picatinny rail. You can also see the four brass screws that just kiss the action to fully stabilize it in the tube. The recoil ring buttresses completely around the action with metal to metal contact. There are a million details hidden inside a Gary gun.”

Rise of the Phoenix — Here are the sights for the Eliseo R1. There are very few manufacturers left making these kinds of ultra-precise and repeatable iron sights.

These Ray-Vin tools help set mechanical zero on the sights. Dennis notes: “Finally a reason to pull out the Ray-Vin calibration paraphernalia to set up a mechanical zero. This photo is for all of you who still remember that those barrel flats and screws in our sight towers actually had a purpose once upon a time.”

Dennis plans to use Peterson Cartridge Small Rifle primer .308 Win brass. Peterson offers a “Select” version weight-sorted and length-sorted at the factory. All Select casings (in a 50ct box) are guaranteed to be within 1 grain in weight and .001″ in OAL. Peterson Select brass is available for 20 different cartridge types, including .308 Win both small primer/small flash hole and large primer/large flash hole.

Getting the Blue Rifle Ready for the 2020 Berger SW Nationals

Berger southwest SW Nationals

Dennis plans to campaign his rifle at the 2020 Berger Southwest Nationals (SWN). He may shoot iron sights, or fit a scope and shoot in the “Any Sights” category. That’s not yet decided. The week-long Berger SWN is the biggest rifle match in the Western United States. Hundreds of shooters compete in both individual and team events. The SWN begins with the Mid-Range Nationals at 600 yards. Then the Long-Range matches are held, with targets out to 1000 yards. Watch the video to see the Ben Avery facility, home of the Berger SWN:

Common Misconceptions about Twist Rate and Stabilization

FirearmsID.com barrel rifling diagram

Understanding Twist: Bullet Stabilization

by Sierra Bullets Ballistic Technician Paul Box for Sierra Bullets Blog.

Based on the questions we get on a daily basis on our 800 (Customer Support) line, twist is one of the most misunderstood subjects in the gun field. So let’s look deeper into this mystery and get a better understanding of what twist really means.

When you see the term 1:14″ (1-14) or 1:9″ twist, just exactly what does this mean? A rifle having a 1:14″ twist means the bullet will rotate one complete revolution every fourteen inches of the barrel. Naturally a 1:9″ turns one time every nine inches that it travels down the barrel. Now, here’s something that some people have trouble with. I’ve had calls from shooters thinking that a 1:14″ twist was faster than a 1:9″ because the number was higher with the 1:14″. The easiest way to remember this is the higher the number, the slower the twist rate is.

Now, the biggest misconception is that if a shooter has a .223 with a 1:8″ twist, his rifle won’t stabilize a 55gr bullet or anything lighter. So let’s look at what is required. The longer a bullet is for its diameter, the faster the twist has to be to stabilize it. In the case of the .223 with a 1:8″ twist, this was designed to stabilize 80gr bullets in this diameter. In truth the opposite is true. A 1:8″ will spin a 55gr faster than what is required in order to stabilize that length of bullet. If you have a bullet with good concentricity in its jacket, over-spinning it will not [normally] hurt its accuracy potential. [Editor’s Note: In addition, the faster twist rate will not, normally, decrease velocity significantly. That’s been confirmed by testing done by Bryan Litz’s Applied Ballistics Labs. There may be some minor speed loss.]

FirearmsID.com barrel rifling diagram
Many barrel-makers mark the twist rate and bore dimensions on their barrel blanks.

Think of it like tires on your truck. If you have a new set of tires put on your truck, and they balance them proper at the tire shop, you can drive down a street in town at 35 MPH and they spin perfect. You can get out on the highway and drive 65 MPH and they still spin perfect. A bullet acts the same way.

Once I loaded some 35gr HP bullets in a 22-250 Ackley with a 1:8″ twist. After putting three shots down range, the average velocity was 4584 FPS with an RPM level of 412,560. The group measured .750″ at 100 yards. This is a clear example that it is hard to over-stabilize a good bullet.
