Looks like a Lapua Naralis, but the current ones don't have any steel in the jacket and have green tips. A yellow tip is used to mark tracer and spotter military ammo, I would section one, but doubt that is what you have. Norma had some steel jacketed loads but not sure about that one.

If 286 grain then the Norma Dual Core.
