I can say don't rely on penetration... I know better but had no choice.. only had a kimber ultra carry 3 inch following up a buddies wounded doe... found her bedded in thick south Texas brush.... but before I could locate the head she jumped... I dropped 4 quick rounds as she got up and left in a hurry.
Went to get a Catahoula... had to shoot her in the head a while later with the 45 once bayed.
All 4 of my previous rounds had hit her as she left, none had made it far enough past the hips/hinds to penetrate the organs.
I keep my mag staggered 230 ball and 230 whatever HP I happen to have around... I think these were WW but am not sure.
I've shot a couple broadside with no issues.
I have one of thoses Ultra Kimbers and mine barely breaks 700 FPS with +P 230's
The 4" Colt Officer model doesn't lose nearly as much velocity.
