There were some problems with the cupro-nickle jackets and bore fouling in the early years of use, particularly in the 303 British, but powders and other developments have pretty well eliminated that issue. These 6.5x55 rounds are, in many rifles, astoundingly accurate. Norma also made a large number of softpoint hunting rounds with a jacket that looks similar, but is not. These hunting rounds have a nicely formed mild steel jacket with a generous softpoint exposed, and usually work very well in game at hunting distances. The original 180 grain SP ammo for the 308 Norma Mag used this type of bullet, as did a number of other chamberings. At home right now, as components, I have some of these Norma MS jacketed softpoints in 6.5mm/139; 270/130; 7mm/150; 308/180 & 8mm/196. I have several recovered from game, and all look classic.
