A small base sizing die squeezes the brass case down just a little bit more than a regular sizing die, which can be important for semi-automatic rifles. This extra sizing helps to ensure reliable feeding and extraction, and is especially useful for reloading ammunition for AR-style rifles.
A taper crimp seating die is used to apply a slight crimp to the case mouth, which helps to keep the bullet securely seated in place. This is important for semi-automatic rifles, as recoil can cause bullets to move slightly within the case. The taper crimp is gentler than other types of crimps, which can deform the case mouth and decrease accuracy.
Progressive reloaders use machines that can automatically cycle through the reloading process, which can be faster and more efficient than reloading by hand. However, these machines require specialized dies that can handle the high volumes of ammunition being produced. The RCBS and Bushnell Hunting Reloading Dies are both designed specifically for AR-style or semi-auto shooters, making them the ideal choice for progressive reloaders who demand high quality and reliability.
