I have always shot deer aiming for the heart / lung area, so just shooting through ribs and vitals. Had a bad experience last year when I shot a deer at 40 yds with a 245-250 gr. powerbelt w/ ballistic tip. Small hole in small hole out. On snow, I could not find blood except for a few small droplets over a 70 yd distance before the deer went into cover, where I did not pursue because I was figuring I caught her in the gut and I didn't want to push her. She was found the next morning 25 yds from where I stopped looking and was hit nicely where I wanted and had caught some lung. I have shot the Barnes expander which grouped fairly well at 100 and also the tipped MZ which I'm going to try on deer, that also shoots well. Are some shooters aiming for shoulder bone or elsewhere that I should consider with a harder or less expandind bullet design? What's your prefered shot and bullet combo? I either want to drop 'em or have a good blood trail in case there isn't snow!
