Technology and innovation are the key to achieve leadership on the international market; thatʼs why the U.S.-based Winchester Ammunition company conveyed the bulk of its financial resources to its R&D sector, in order to conceive and develop specialized ammunition loads that would satisfy the needs of the most demanding hunters anywhere, anytime. The result was the new line of high-penetration, highly-frangible Power Core 95/5 ammunition for cloven-hoofed game hunting.
The entire Winchester Power Core 95/5 line is loaded with tombacco-alloy hollowpoint bullets that will quickly expand in the game tissue; the patented controlled expansion capability will help the bullet retain the original weight to achieve deeper penetration even after expanded in four symmetric, progressively enlarging petals to increase energy transmission on the target for maximum lethality.
The Power Core 95/5 line is part of Winchesterʼs Super X brand and is available in the twelve most popular hunting calibers. Further addictions to the line are planned for the near future, and new developments are in fact looked forward at for introduction at the upcoming SHOT Show. The following tables sum up the main technical features of the Power Core 95/5 ammunition line.
