Soft-point bullet have become available for safe use in tubular magazine rifles. Soft-point bullet A soft-point bullet (SP), also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually abbreviated "JSP" in the ammunition and reloading industry. Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants like cordite. By
Parasitic element (electrical networks) Parasitic element (electrical networks) In electrical networks, a parasitic element is a circuit element (resistance, inductance or capacitance) that is possessed by an electrical component but which it is not desirable for it to have for its intended purpose. For instance, a resistor is designed to possess resistance, but will also possess unwanted parasitic capacitance. Parasitic elements are unavoidable. All conductors possess resistance and inductance and the principles of duality ensure that where there is inductance, there will also be capacitance. Component designers will strive to minimise parasitic elements but are unable to completely eliminate them. The most commonly seen
