I spoke to Wolf and they said the jacket of the 9mm 115g bullet is a steel and lead mixture (bimetal), but the projectile doesn't have a steel core. Rule 5.5.3 says the below. So that round isn't steel core nor is it a steel jacketed projectile (it's steel and lead). Can it still be used in a match or it's a no-go? Thanks
Metal piercing, steel core, incendiary, and/or tracer ammunition, as well as ammunition loaded with steel jacketed projectiles is prohibited at USPSA matches.
Steel case ammunition is allowed, provided the projectile does not stick to a magnet.
