The FX Dynamic .35 Cal: The Ultimate Triple Threat for Airgun Hunting
The FX Dynamic .35 Cal isn’t just another airgun—it’s a game-changer. As someone who’s spent years testing airguns, slinging arrows, and hunting with high-powered precision, I can confidently say this is the most versatile airgun I’ve ever used. The fact that you can fire arrows, heavy slugs, and precision pellets from a single platform, all while maintaining accuracy and power, makes it a Triple Crown winner in my book.
This isn’t about just raw power—it’s about adaptability. Whether you’re stalking big game, testing your skills at long range, or trying something unconventional like airgun arrow hunting, this rifle delivers. I’ve put it through its paces, from field testing to fine-tuning different projectiles, and the results have been nothing short of astounding.
How the FX Dynamic .35 Cal Became My Most Versatile Hunting Tool
My journey with this platform began months ago when I first got my hands on the 700mm barrel kit. Right out of the gate, this setup was pushing over 200 foot-pounds of energy with heavy slugs, making it one of the most powerful airgun hunting rigs I’d ever tested. But it wasn’t until I was tuning my archery gear for the season that I had a wild idea.
What if this airgun could fire arrows?
Having tested arrow-shooting airgun kits in the past, I knew the concept was possible. But with the Smooth Twist X barrel and massive air capacity of the FX Dynamic, I had a hunch this could take arrow-slinging to the next level. So, I grabbed an Air Venturi arrow, loaded it up, and pulled the trigger.
The results were eye-opening. The arrow launched at blistering speed, flying straight and true with an energy level that rivaled high-end crossbows. That first shot sent me down a rabbit hole of testing different arrows, analyzing spine stiffness, and experimenting with barrel lengths to dial in the perfect setup.
The Science of Airgun Arrow Shooting: Solving the Challenges
As promising as that first test was, I quickly ran into challenges. The 700mm barrel, while powerful, left a significant gap between the transfer port and the arrow’s nock. That gap caused arrow paradox, where the arrow flexes in mid-flight due to the intense air pressure hitting the rear.
Accuracy suffered as a result. Even though the arrows were flying at over 500 feet per second, the slight wobble was enough to throw off consistency. At that point, I knew standard archery arrows weren’t going to cut it—I needed to engineer something better.
That led me to the Total Archery Challenge in Traverse City, Michigan, where I met with the team at Boning Archery. Their Air Vane caught my attention—a design made to stabilize high-speed projectiles while maintaining aerodynamic efficiency. By the end of the event, I was holed up in my hotel room, cutting, fletching, and tweaking arrow prototypes like a mad scientist.
Refining the Setup: The 500mm Barrel Breakthrough
After extensive testing, the 500mm barrel kit proved to be the sweet spot. The shorter barrel minimized the paradox effect while stiffening the arrow’s spine, which resulted in flatter trajectories and tighter accuracy.
At this point, I teamed up with Andy Buchanan of Thorn Archery, a leading broadhead designer with extensive experience in archery hunting applications. Together, we pushed the FX Dynamic’s performance further by incorporating a tungsten hammer setup, squeezing every bit of velocity and energy from the platform.
With this setup, I was hitting over 500 feet per second and generating 220 foot-pounds of energy—numbers that put this airgun as one of the most powerful airgun arrow slingers I have ever shot. Watching arrows slam into targets with incredible force and pinpoint accuracy (and often blowing through the box target rated for 500 FPS) was a moment of validation for all the fine-tuning and adjustments.
What the FX Dynamic .35 Cal Can Do Right Out of the Box
After all my tinkering and modifications with that hot-rodded version, I wanted to see how the stock FX Dynamic .35 Cal with the 500mm barrel and GRS stock would perform with no tweaks.
The stock setup delivered 460 feet per second with Air Venturi arrows, producing energy levels that easily matched or exceeded some of the best crossbows on the market. Even more impressive, I was getting 10+ shots per fill without making any adjustments to the regulator. That kind of efficiency, paired with the rifle’s ergonomic GRS stock, made for an awesome out-of-the-box hunting option.
Loading the arrows into the barrel was effortless—just a slight twist to align the vanes, and the arrow seated perfectly, ready to fire. The entire setup felt intuitive, smooth, and built with big game and Deer hunting in mind.
Field Testing: Learning the Marshes of Maryland
To truly test this airgun’s capabilities, I took it to Maryland for a Sika deer hunt with Chad Simon from Lethal Air. This was my first time hunting in the marshes of Maryland, and let me tell you—this environment was nothing like anything I had ever hunted before. Thick, tangled reeds, soggy wetlands, and knee-deep mud made movement slow and silent stalking nearly impossible. Unlike the open terrain I was used to, the Sika deer thrived in these marshes, using the dense cover to their advantage. I quickly realized that this was going to be a whole new challenge.
Navigating through the marsh, I learned how to read the terrain, spot fresh deer sign, and adapt to a style of hunting that was completely foreign to me. It was a steep learning curve, but the FX Dynamic .35 cal, paired with arrows, felt like the perfect tool for the job. The quiet operation and raw power gave me confidence that if I got a shot, it would be clean and ethical.
Unfortunately, I didn’t get the chance to take a Sika deer on this trip. However, Chad Simon returned this past spring and successfully bagged one, proving that the method was effective. Seeing his success has me itching to go back. Next time, I’ll be armed with even more experience and my FX Dynamic .35 cal—and I have no doubt I’ll be putting fresh Sika venison on the table.
Final Thoughts: The Most Versatile Hunting Airgun Ever Made
The FX Dynamic .35 Cal has completely changed how I think about airgun hunting. The ability to shoot arrows, slugs, and pellets from one rifle means you’re never limited by a single hunting style.
Whether you’re hunting big game, precision shooting, or experimenting with new airgun capabilities, this rifle does it all.
After all my testing, one thing is clear—the FX Dynamic .35 Cal isn’t just another airgun. It’s a revolution in airgun hunting.
If you’re serious about taking your airgun adventures to the next level, this is the platform to do it with. Until next time, happy airgunning!
