95 grain Nosler Partition. Have been loading it in my custom 6mm for 20 years. It got the nod over several good bullets mentioned here because of how it shot in my varmint barrelled Mauser: under 1/2 MOA all day long. A few years ago I bought a .243 and stayed with the 95 NP because I have it on hand.
Have killed several whitetails, several blacktails, black bears, antelope, one large bull elk when it was the rifle in hand and likely some I'm forgetting. The 95 NP is a consistent killer with deep penetration, plenty of wound along the way, and almost always an exit.
Only downside is boring consistency.
