Ammunition reloading is the practice of recovering expended cartridge cases, sizing the brass, and recharging with primer, powder, and bullet. Only Boxer primed brass cartridge cases are suitable for this purpose. A modest investment in reloading equipment can result in a considerable reduction in ammunition cost if fairly high volumes are involved. This is especially true if a group of shooters who regularly use the same ammunition type combine time and resources to produce their own ammo in quantity. Reasonable care will produce very high quality ammunition.
Many companies specialize in providing information, equipment, and components for reloaders.
Carry slings for rifles and carbines should provide for slinging the weapon on the shoulder for common carry, over the back for freeing the arms and hands for other tasks, and slinging the weapon in the front at the ready. Adjustable nylon carry slings are available that meet these criteria for many weapons, and do a passable job as shooting slings. Shooting slings are designed to aid the shooter in stabilizing the weapon on target, but are slow to bring into action and passing from common use. A protective case is handy for transporting your weapon when traveling. Padded ballistic nylon cases are good for use in private vehicles on trips to and from the shooting range, etc.
