Drain rock,
I've got a Uberti SAA with a 5 1/2" barrel that is a great packin' gun much like what you've got planned. I like that weapon for carry too.
Due to avoiding a real nasty bear and dog tangle, I shot urus several times while I had a open shot in the tree.
The fellow shaking my hand in the picture, Shaun Anderson advised me to keep taking shots while I could to ensure that the bear did not hit the ground with any life in it, as that we did have dogs present and in the meley if it could put up a fight would be impossible to seperate dog and bear for a clear shot once on the ground.
The first was through the heart lungs and probably was the killer shot, the second went from a front facing bear, through the shoulder, and just as it fell, the third (aimed at the chest) was a head shot.
Those XTPs penetrated clear through, and I did recover one from the shoulder shot, it hadn't expanded or opened up at all, It looked pristene except for the rifling marks. (so much for the "expanding type" bullet theory.)
