Well about five years ago I shot a good black bear, using a SRH 44mag, open sites, I was still stalking at dust, going to my stand, suddenly I see a big black abject to the left of me, bye the time my mind realized it was a bear he was running across me, I took a good stance got him in my site, squeezed one good one at about thirsty yards, I know I hit him due to the fur displacement, he kept going like nothing hit him, so I follow up with double action, caught him with the 4th shot, he dropped and skidded across the leaves, then was trying to get up, two more shots I thought I missed due to him moving all around, Luckily I had a speed loader ready to be used, I reloaded so fast I could not believe myself, but I did not want to loose that bear. I got one more shot into his chest area, this last shot did him in, but must say, everything happened so fast, when checking the bear for shot I found four shots in his shoulder and chest area, he only reacted to the first and the fourth shot, Kupdagrass on the last, I was using 240ge xtp's on top of 24gr win296, ccimag primers. This is where the double action shined, your right about how fast they can be. The best way to hunt the field is to imagine there is always a chance of seeing something any time, this way you are prepared for action, and will be able to react when needed, other wise you experience bear fever;) Aim small hit small.
