Getting Started with GRT: Why It’s a Game-Changer for Reloaders
Share
Reloading is more than just pouring powder and seating bullets. For South African shooters and hunters, it’s about precision, safety, and performance. That’s where Gordon’s Reloading Tool (GRT) steps in.
GRT is a powerful, free ballistics simulation program that takes the guesswork out of load development. Whether you’re fine-tuning your hunting rifle or pushing your competition pistol to the next level, GRT helps you predict how your loads will perform — all before you fire a single shot.
Why GRT Deserves a Spot on Your Bench
-
Accuracy at your fingertips – Simulate chamber pressures, velocities, and trajectories tailored to your specific firearm.
-
Save money and components – Test dozens of virtual loads without wasting powder, primers, or bullets.
-
Fine-tuned customisation – Experiment with burn rates, seating depths, and case capacities in a safe, controlled environment.
-
Confidence on the range – Walk into load testing with data-driven expectations instead of blind guesses.
What You’ll Need to Begin
-
A computer (Windows/Linux) with GRT installed (free download).
-
Component details like bullet weight, powder type, and barrel length.
-
A willingness to learn the basics of internal ballistics (don’t worry — we’ll guide you step by step).
Why It Matters for South African Reloaders
Reloading components are expensive, and finding the perfect load can burn through time, ammo, and patience. With GRT, you cut down on trial-and-error and head to the range with a clear plan. For hunters, it means ethical, accurate shots. For sport shooters, it means tighter groups and consistent performance.
