Alacran,
To be honest, I can't think of a single critter that needed a finishing shot after being clobbered with the .58.
When I hunted with a .54 I used 120 grs 2F, but going by Jim Chambers advice, I tried 70 grs of 2F in the .58 and it worked, so never changed it.
Very little bloodshot meat, and yes, you can eat right up to the bullet hole.
Very very few balls recovered from deer sized critters.
