I remember back a few years, I shot a doe at about 40 yds, and when she got hit she went down and tried to get back up. It didn't happen. At the time, I had wondered if I should trade the 30-30 for a single-shot 30-06. After the shot, the thought of trading it went out the window. BTW, as I remember they were 170 gr coreloks. I think that I'll rethink and decide between the 150;s and the 170's.
