theo,
The failsafe doesn't perform like most folks think a hollow point performs.
In fact there may not be any bullets out there that provide deeper penetration than the failsafe (exc. solids).

Sounds like the bullet you are looking for is the Nosler Partition. Give them a try.

Barnes triple shock is another excellent bullet. The Partition will give you a bit more expansion and a little less penetration than the triple shock.

The triple shock is a VERY accurate bullet.
