I have shot and had bome hits with all but the Ribteks. The zwickey was my go to broadhead and I was leaving the point as it came. Had a few issues early on and was shown how to modify to a slight tanto tip. You only want to use 2 or 3 strokes of each of the four sides of the broadhead to make the point. After I was shown this I have never had another issue with a bone hit. I have only shot the other broadheads with the modified point, so can not comment on bone hit with original points.
