Extreme long-range shooting demands perfection. In a recent Ultimate Reloader video, Gavin Gear teams up with world champion shooter Paul Phillips to attempt a two-mile impact, a feat that pushes both shooter and equipment to their limits. With the bullet in the air for over seven seconds, there’s no margin for error.
Central to their success was a precision-cut chamber made possible by Manson Reamers. Using custom chamber reamers matched to their load, the team built a rifle from the ground up capable of sub-half MOA performance, the kind of accuracy needed to achieve impacts at two miles.
Building a Custom Rifle With Manson Reamers
Rather than modifying an existing platform, Gavin and Paul built this rifle from scratch to perform at extreme ranges. Starting with a BBat EX action from a previous .50 BMG build, they sourced components specifically chosen for their ability to deliver precision. The rifle was fitted with a Bartlein barrel, Accurate Rifle Systems chassis, and an advanced optics package.
At the heart of this process was a Manson Custom Chamber Reamer. As Gavin explains in the video:
“It’s been really helpful to have your reamer schematic. I talked to Manson Reamers and got the exact reamer used for the 400-grain laser .375 Shyac load.”
Using a custom chamber reamer ensured the chamber dimensions were perfectly matched to their ammunition. This step laid the foundation for exceptional consistency, accuracy, and bullet stability, essential factors when shooting beyond a mile.
Custom Chamber Reamers Deliver Perfect Tolerances
At extreme distances, even thousandths of an inch matter. A chamber that’s slightly off-spec can cause inconsistent pressures, poor bullet alignment, and unstable flight paths. By using custom chamber reamers from Manson, the team achieved:
- Exact tolerances for a flawless chamber-to-cartridge fit
- Consistent headspacing for reliable ignition and velocity
- Improved bullet stability for tighter groups at any distance
This precision machining paid off immediately. During testing, the rifle produced sub-half MOA groups at 100 yards, proving that the chamber was cut to exacting standards. Without the reliability provided by Manson Reamers, their two-mile shot wouldn’t have been possible.
Precision Shooting Requires More Than Great Gear
The video is a masterclass in extreme long-range shooting. Paul Phillips, a multi-time King of Two-Mile champion, applied his decades of ELR experience to the build, using proven formulas from competitive shooting and U.S. Rifle Team success.
They accounted for every factor affecting bullet flight, including:
- Spin drift and Coriolis effect
- Wind direction, mirage, and environmental shifts
- Precise elevation calculations using custom optics and mounts
Even with cutting-edge technology, the rifle’s performance still depended on a perfectly cut chamber. Thanks to Manson Reamers and their custom chamber reamers, the rifle delivered consistent velocities and stable flight, which is critical when the bullet spends seven seconds in the air.
Why Gunsmiths and Competitors Choose Manson Reamers
Professional gunsmiths, competitive shooters, and precision rifle builders rely on Manson Reamers for one simple reason: results. Whether you’re chambering for extreme long-range, hunting, or tactical applications, custom chamber reamers from Manson deliver unmatched performance.
- Precision engineering for flawless chamber geometry
- Custom solutions designed for your exact load and platform
- Trusted performance proven in competition and by military professionals
In the Ultimate Reloader build, Manson’s contribution was essential. The exact chamber dimensions dictated bullet stability, velocity consistency, and ultimately, whether impacts at two miles were possible.
Build With Confidence Using Manson Reamers
The two-mile achievement featured in the video wasn’t luck. It was the result of expertise, meticulous planning, and precision tooling. When every thousandth of an inch matters, Manson Reamers and their custom chamber reamers provide the confidence builders and shooters need to push the limits of accuracy.
From competition-ready rifles to hunting platforms and tactical builds, Manson delivers the solutions professionals trust. If you want precision without compromise, start where it matters most — the chamber.
