Not totally true. Several years ago Winchester and Nosler cooperated on the design of the Ballistic Silvertip and came up with the "Combined Technology" group of ammo. "Ballistic Silvertip" is a joint trademark of both Winchester and Nosler equally. All other "Ballistic Tip" bullets and ammo are trademarked by Nosler only.
