i used the 275 grain bloodlines this year for the first time based on sabotloaders recommendation. they are a very good bullet. i shot a whitetail doe on my antlerless tag that was quartering hard to me through the front left shoulder and out just behind the last rib and she dropped right where she stood. the following day i dropped a 2x3 mule deer in its tracks from 70 yards with a shot to the neck. the bloodlines fly really well out of my gun (knight disc) and had 2-3 inch groups at 160 yards off the bench. i used 120 grains of 3f and was about 4 inches high at 100 yards and 4 inches low at 200 yards. just point and shoot!
