Quickload vs Gordon Reloading Tool (GRT)

QuickLOAD and Gordon Reloading Tool (GRT) are established internal ballistics applications used by handloaders and precision shooters to evaluate potential load configurations. Both programs simulate how variations in components and setup—such as bullet selection, powder charge, and cartridge dimensions—can influence chamber pressure, muzzle velocity, and related performance metrics. Their primary objective is to provide analytical insight before any live-fire validation takes place.

In practical use, each platform enables detailed data entry, including case capacity, projectile characteristics, propellant type, and charge weight. Based on these inputs, the software generates predictive calculations describing internal ballistic behavior. Comprehensive libraries of cartridges, bullets, and powders are included in both systems, allowing users to compare combinations and assess how incremental adjustments—like seating depth or powder changes—may alter pressure curves and velocity projections. Rather than serving as static reference tables, both applications function as configurable simulation tools.

While they share core capabilities, the two programs differ in design approach and development trajectory. QuickLOAD, created by Dipl.-Ing. Hartmut G. Brömel, is often viewed as one of the pioneering consumer-level internal ballistics simulators. It is distributed as a Windows-based desktop application and reflects a traditional software layout focused on dense numerical output. Although its database historically covered a wide spectrum of components, update frequency in recent years has been limited, which can affect representation of newer propellants and projectiles.

GRT, developed by Gordon Morrison, emphasizes a structured and component-driven workflow. Its interface organizes calculations into clearly arranged tables and editable fields, supporting systematic comparison of load variations. The program continues to receive updates, incorporating refinements to its datasets and modeling algorithms, supported by ongoing user feedback.

An additional option in this category is ApexLOAD PRO, a browser-based system derived from the QuickLOAD modeling concept. It introduces cloud accessibility, centralized data management, and collaborative feature development, representing a different modernization path within the internal ballistics software landscape.
