Myself, I'm trying to stay neutral on this subject of discussion. But comparing a crossbow bolt to a small calibre centrefire bullet, (for a heart shot) is too much of a stretch IMO. I argue that what could be done dozens of times with a crossbow bolt, is quite a gamble with the Hornet and it's usually utilized varmint bullet. Weaving a fox bullet to the deer's heart, means dodging the ribs at least with a super explosive bullet jacket.
I take it you are kind of unfamiliar with the .22 centrefires?
