Percussion Point
The percussion point projectiles are designed for rapid expansion on the big cats as well as other large thin skinned game.
How They Work
Percussion Points are specifically designed for use on thin skinned dangerous game, such as the big cats. They are designed to mushroom rapidly, to quickly impart massive shock. A highly desireable quality when facing dangerous game. The tapered jacket ensures that the projectle mushrooms in a controlled manner, regardless of impact velocity.
Design Features
Construction – The bonded lead core remains with the jacket upon expansion, retaining maximum projectile weight and a uniform expansion shape, for straight line penetration. The solid copper base ensure that expansion cannot continue beyond the lead core front section, ensuring deep penetration at higher velocities.
Meplat – The exposed lead tip and etching just back from the meplat promotes rapid expansion on thin skinned game for maximum trauma. The also provides the projectile with both visual and tactile cues to ensure positive identification and distinction from other projectile types.
Bonded Core - The copper walls containing the lead core are taper cut to ensure that they 'peel' open gradually in a controlled manner. This way, even at high impact velocities the projectile will mushroom consistently and not come apart. North Fork call this 'Designed Impact Geometries'. The bottom of the lead core has a reversed ogive shape to ensure that the copper jacket has greatest strength at maximum expansion, and prevents the front section from separating.
Driving Bands – North Fork's 'Smart Band Technology' TM utilises multiple thin driving bands. These not only conform to the bore to ensure a positive gas seal with virtually no barrel fouling, but also reduce chamber pressures by effectively halving the bearing surface, to greatly reduce friction.
Range of Weights – Percussion Points come in a range of dangerous game calibres from .375 to .458 and come in different weights within each available calibre.
Note: Because these projectiles have solid bases, they are longer than pure lead core projectiles of the same weight. As such, they may require a faster twist than the same weight lead core projectile. Please check the Technical Data Sheet to ensure that the projectiles you are interested in are compatible with your rifle's barrel twist rate.
