In this episode of TFB Behind the Gun Podcast, we sit down with Bill Reilly, founder of SIM-X Ammunition, to unpack the story behind his company and its practical take on ammo design for training, competition, and self-defense. Bill opens up about how his hobby of shooting in his basement drove him back to school and sparked the creation of SIM-X. He breaks down the ammo’s competition roots and how it’s engineered for performance in both training and matches. Operating out of northern Salt Lake City, Utah, SIM-X focuses on lightweight, high-velocity rounds tailored for shooters who value function and reliability. We dig into Bill’s journey and explore how SIM-X goes beyond performance, contributing to healthier shooting habits with its lead-free ammunition in a no-nonsense chat about what’s next for the industry.
