Norma African PH 404 Jeffery Ammo 450 Grain Woodleigh Weldcore Soft Nose review offers the following information;Norma AFRICAN PH is a series of tried and tested steel mantle balls and bonded lead tip bullets that have been combined with Norma sleeves and high-quality gunpowder. The series is loaded under the most stringent inspection standards in the industry to always deliver the highest quality. Nickel-plated sleeves are used to ensure repetition and ejection of the sleeve from the rifle, even when the rifle is too hot to touch or full of the inevitable African sand. Powder and lighter hat are carefully selected to minimize variations between different charging times. Norma's goal with the AFRICAN PH series is that you should always be able to buy ash cartridges, anywhere in the world, and get the same performance as those you use at home!
