As a member of the World Champion Team USA F/TR squad, Paul Phillips regularly competes (and wins) at 1000 yards. Paul is also a long-range hunter. Here’s his story about developing his ultimate long-range hunting rifle. Chambered for the .338 Lapua Magnum, this rig is accurate out to 1800 yards.
The Long-Range Challenge By Paul Phillips
Being an avid big game rifle hunter, my goal was to build the most accurate long-range hunting rifle possible that would still be light enough to carry. My thought was to use the same type of high-quality components as what I used on my US F/TR Team Rifle, except in a bigger caliber — a caliber that would have plenty of knock-down power at very long ranges. After extensive research, including both ballistic data analysis, as well as discussion with top gunsmiths and champion long-range shooters, I chose the .338 Lapua Magnum. My past experience from being a member of a USMC Scout Sniper Platoon and a shooting member of two World Champion U.S. F-Class F/TR teams, I knew that this rifle was more than capable of performing the task. After establishing that the rifle had half-MOA accuracy at 600 yards, we wanted to see how far the rifle could maintain sub-MOA accuracy, to see what the cartridge and rifle could achieve. Could this gun shoot sub-MOA at a mile? That was our challenge.
Rifle Components and Gunsmithing
My rifle was built on a Stiller Tac-338 single-shot action. It has a 30″, 1:10″-twist Brux barrel, a McMillan A-5 stock with Magnum fill, a Sinclair Bipod, and a Remington X-Mark trigger set at two pounds. The rifle wears a Nightforce NXS 8-32x56mm scope in Nightforce rings on a +40 MOA rail. I chose David Tooley to install the barrel, custom brake, apply a Cerakote dark earth finish and bed the stock. After speaking with Mr. Tooley in great length, I chose his no-neck-turn match .338 Lapua chamber specifically designed for the 300 grain Berger Bullet. This rifle weighs 17 pounds and, with the muzzle brake, it recoils like a standard .308 Winchester.
Load Development and Accuracy Testing
I used the 600-yard range at the Midland County Sportsman’s Club. If I was going to have any chance of hitting small targets at a mile, I would need to find a load that could produce half-minute (0.5 MOA) or better accuracy. I found an accurate load that gave me consistent half-minute groups that chronographed at 2825 FPS. My load consisted of Lapua brass, Federal 215M Primer, Alliant Reloder 25, and Berger 300gr Hybrid OTM bullet. With the Berger 300-grainer’s listed 0.419 G7 BC, this load would be good enough to reach 1880 yards before going subsonic. This load’s calculated energy at one mile is 960 ft/pounds. This is similar to a .44 magnum pistol round at point-blank range.
With my +40 MOA scope rail, my 100-yard zero ended up with the elevation at the bottom of the tube and the windage just 2 MOA left of center. This left a full 65 Minutes of Elevation — enough to get out to 1800 yards. This gave me the capability to aim and shoot from 100 yards to 1800 yards with a projectile that is still supersonic at 1800.
Hitting a 10″ Balloon at One Mile
For a one-mile target, I chose a balloon inflated to 10″ in diameter. The balloon would be a challenging, reactive target that would show up well on video. I teamed up with a fellow long-range shooter, John Droelle and friend Justin Fargo to attempt this feat. Using my known 600-yard Zero, my ballistics program showed my come-up for 1783 yards to be 53 MOA. After two sighters that measured 4 inches apart, I adjusted up one minute from my spotter shot and nailed my 10″ balloon at one mile. This video was recorded with my iPhone attached to my 25-power Kowa spotting scope, so it may seem a lot closer than it really is. Below is a video of the shot. Needless to say I achieved my goal and was very excited.
Watch Hit on 10″-Diameter Balloon at One Mile with .338 Lapua Magnum
After my balloon shot, I let my friend Justin Fargo, a novice shooter, try his skills. Justin told me that he had never shot past 100 yards using a common deer rifle. Surprisingly, Justin not only kept all his shots under 1 MOA, he hit the 9-inch white circle in the middle of the target. This bullet hole measured only 4.3 inches from the center of where he was aiming. Truly amazing! The target below shows Justin’s shots at one mile. Note that All the hits are located within the 24-inch black circle.
What I Learned — With the Right Equipment, Even a Novice Can Make Hits at a Mile
The above results demonstrate that even a novice shooter with a high-quality, custom rifle and match-grade ammo can make extreme long range shots with great accuracy. It is very important to understand the ballistics of the bullet and the effect of wind drift to make precision, first-shot hits on your target. It is also important that you know your target, backstop and beyond when making these shots. To date, I have shot approximately 40 shots at a mile in calm conditions while averaging 3-shot groups between ½ to 1 MOA (1 MOA is about 18.5″ at that distance). My next experiment is to see how well these bullets perform traveling at subsonic speeds out to 1.5 – 2 miles. Stay tuned!

Editor’s Comment: The point of this article is to show the kind of accuracy a precision rifle system can achieve, consistently, at extreme long range. Though this rifle will do duty as a hunting arm, Phillips is not advocating that a .338 LM be used to harvest animals at the full limit of its supersonic range. Because winds are hard to predict at extreme long range in a hunting situation, Phillips cautions that the practical distance at which he would shoot game with a rig like this is much, much shorter.
