When did Winchester transition..

When did Winchester transition to nickel cases and Ballistic Silvertips in their Supreme line of ammo? I found a couple boxes of older Supreme with standard brass cases and older standard style Silver Tip bullets...I'm assuming these are early 90s, maybe late 80s?

You are correct on that ammo vintage. Possibly mid 90s.
