Sunday GunDay: Super-Light 5-Lb Titanium Action Hunting Rifle
Here is Tom Mousel with Whitetail taken with his ultra-light hunting rifle fitted with 6mm Creedmoor Lilja barrel. Friend Cody (right) actually took the shot. This gun has a second barrel in 6.5 Creedmoor.
Hunting season is opening up soon across the country. In just three weeks, on 9/26/2026, the nation celebrates National Hunting & Fishing Day. This Sunday we feature an impressive state-of-the-art, ultra-light hunting rifle. This rig is very accurate AND very light, and features two barrels, one in 6mm Creedmoor and the other in 6.5 Creedmoor. With this Titanium-actioned rifle, owner Tom Mousel has successful taken Whitetail deer and other game.
National Hunting & Fishing Day is set for September 26, 2026, 20 days from now.
“Light is Right” when it comes to carrying deer rifles long distances in the backcountry. A lighter rifle DOES make a difference when you’re hiking many miles and carrying other gear including binoculars, laser rangefinders, food/water, and packs. And then, if you are successful, you’ll be carrying out game meat, so a lighter rifle translates to a lighter overall load.
When Forum member Tom Mousel (a top 1000-yard competitor) considered a new hunting rifle, he wanted a very light-weight rig. What he got was a low mass masterpiece — an ultra-accurate, five-pound hunting rifle. Not only does this twin-barrel rifle, as built by Alex Wheeler, come in under five pounds (before optics), but it has produced some quarter-MOA 3-shot groups at 1000 yards. The 6mm Creedmoor version of this rifle has demonstrated truly stellar accuracy at long range. The 6.5 Creedmoor barrel also shoots well and packs more punch for hunting use.

Here is Tom’s rifle weighing in at 4 pounds, 14 ounces with 21″ Lilja #1 contour 6mm barrel. Tom says: “Here’s the rifle with full Titanium action, bolt, and lug, in a Tom Manners 17 oz. carbon fiber stock. It’s exactly one pound heavier fitted with my Leupold Mark AR 4-12x40mm scope in Talley rings.”
Tom has two barrels for the rifle, one chambered for 6.5 Creedmoor and the other for 6mm Creedmoor. Tom reports: “The 6.5mm is a bit lighter being fluted. But I won’t be switching back now that I’ve shot the 6mm version. Neither has too much recoil, but the 6mm CM just kills the 6.5mm at distance for groups.”
Tom tells us: “What I like about this rifle is there were no corners cut to make it light. On some other ultra-lights, the fore-end has no strength or they are cut down really short. This is a full-sized stock, pillar-bedded with aluminum-filled epoxy and free-floated barrel. The ignition is set up with a TON of firing pin fall to function in the coldest temps.”
Gunsmith Alex Wheeler of Wheeler Accuracy is pleased with how this project turned out: “Tom has shot a bunch of sub-5″ groups and a couple one-inchers back-to-back at 1K. He has the Berger 115gr VLD going about 3050 fps.” Tom noted the 6mm barrel picked up about 50-60 FPS after the first 50 rounds. He shoots 115gr Berger VLDs with CCI 450s and Reloder 16, with the Bergers about .005″-.008″ in the lands.
Groups at 1000 Yards with 6mm Creedmoor Barrel, 115gr Bergers
Here are two of Tom’s 1000-yard targets. This is with the 6mm Creedmoor barrel shooting 115gr Berger VLDs pushed by Alliant Reloder 16 at about 3050 FPS. The average of the two groups is 0.246 MOA. Pretty amazing for an ultra-light rifle shot off a bipod. Tom acknowledges that he can’t do this every day. He says that “shooting 871 yards at my home range, the rifle typically shoots 4″ to 5″ 3-shot groups”.
Q & A with Tom Mousel About his Ultra-Light Hunting Rifle
Q: Why did you choose to build this rig?
Tom: I just wanted to do it to see how light we could build an accurate, good-shooting rifle.
Q: What are your favorite things about the rifle, and is there anything you would change?
Tom: Definitely the light weight, and the overall size — it has a pretty short barrel (21″), so it’s just handy. I wouldn’t change anything about the rifle, now that I have the Titanium bolt. When I bought the action originally it had the steel bolt.
Q: How does this rifle handle?
Tom: It points well considering it is a light rifle. The 6mm Creedmoor version has very little recoil. On a good bipod I can sight in at 1000 without a spotter.
Q: What are your favorite accessories?
I use a Solo Hntr Mtn Lite stretchy cover. You can see it in the photo at right showing me on a hunt. I like this because you can roll it up like a sock and and use it for a rear support.
Q: Why did you choose Alliant Reloder 16 powder?
Tom: Lonnie Anderson, a fellow Deep Creek shooter, did a 6mm Creedmoor and he said RL16 was absolutely the most accurate. We have also found that Reloder 16 is really consistent on velocities through the seasons — from 90 above to teens below zero.
Q: Could this ultra-light set-up work for a bigger caliber also?
Tom: I’ve tried bigger calibers, but I’ve never been satisfied with the consistency of the groups. There’s a cut-off — there’s too much torque and recoil. We see a limit — you don’t want “too much gun” for the platform. Even here, the 6.5 barrel just doesn’t shoot as well as the 6mm.
Q: What advice do you have for hunters considering ultra-light rifles?
Tom: Be careful about falling in love with ballistics and trying to build too much bang for too small a platform. If I built a 7mm WSM for example, I’d want to rifle to weigh at least two pounds more.
Full Titanium Action from Pierce Engineering
This photo shows the Pierce Engineering Titanium Featherweight short action featuring Titanium (Ti) receiver, Ti bolt, and Ti lug. This unit is a mere 15.90 ounces complete. (NOTE: with Titanium body and STEEL bolt the weight is 18.5 ounces). The long action version is 17.4 ounces for the complete Titanium action with Ti bolt and Ti lug.
Jud at Pierce Engineering tells us: “Both the Ti action body and Ti bolt are DLC-coated. This action also has an anti-bind rail for added smoothness and ease of functioning. This really is one of the lightest actions on the market. If you’re looking into building an ultra-light rifle I would seriously check one out! We make these with the highest level of detail, pride, and machining tolerances. They’re just sweet actions… and our Ti Featherweight short action is roughly half the weight of a Remington Model 7. So there’s a significant weight savings with the Pierce Ti Featherweight over a Model 7.”
Owner Profile — Tom Mousel, Hunter AND Long-Range Benchrest Ace
Tom Mousel knows a few things about accurate rifles. He is a top 1000-yard competitor at IBS matches and at the Deep Creek range near Missoula, Montana. In 2016 Tom set a remarkable 6-match Light Gun Group World Record, with a 2.9540″ group size Aggregate for SIX matches. And a year later, in 2017, Mousel set a 10-Match Heavy Gun World Record with a 5.3376″ Aggregate. NOTE: that is for TEN-shot groups in Heavy Gun. That’s an average ten-shot group under 6 inches for 10 matches! Over the past decade, Tom has remained at the top of the 1000-yard game, with many match wins at Deep Creek and other ranges.
