I have used Meat seekers the past two years, killing 8 does with them. I don't believe I will ever switch back to fixed blades. Every shot was a pass through leaving a devastating wound channel. The only one that went 100 yards was one that I shot too far back. But I did see her crash right at 100 yards I backed out and gave her a few hours and she was dead. Most have only gone 20 yards. One doe jumped on impact and for a split second I thought I missed until I saw the blood spraying out on both sides. She dropped right there after about 30 seconds. I would highly reccomend meat seekers although the O-rings can sometimes be a pain.
