ABSTRACT:
The research and development of new materials and technologies orient the design, development, and construction of new sport optics products across the globe. With each improvement, whether in a riflescope or accessories, the final product must function without fail in the customer's hand and under the required specification conditions. Therefore, before the product is placed on the market it must be subject to a series of procedures, which involve both performing numerical analysis and physical tests to increase confidence and reliability. Numerical analyses require input data, and that must be consistent with real actions that influence the product to react. In the development of shooting equipment, the rifle recoil is considered the primary reaction for riflescopes, rifles, and accessories alike and is the most significant factor that could cause failure. For this reason, it is essential to use a load development process to have consistent energies, velocities, recoil curves, and reactions. This paper will present, discuss, and analyze the efficacy of the Optimum Charge Weight (OCW), ladder, chronograph, and barrel acceleration Fast Fourier Transform (FFT) load development methods and the results of each in load development.
