NORMA and other Premium European makers have used this plated steel jacket in their hunting ammo in the past with no bore problems. Winchester/US Govt testing on bullet jackets and bore wear showed no difference between plated MILD Steel jackets and traditional gilding metal jacketed projectiles. The bimetal jackets are used in many USA and most foreign modern small arms ammuntion.
It's the Propellant and the 50,000psi BLOW TORCH flame that cuts/wears the throat out of a barrel long before any effect of the bullet running down the bore makes a difference.
