Yes. that's what I did when I came out of the woods this morning. I always keep a spare field tip in my pack in case I forget the target arrow. It's carrying the block target around for the discharge that's a bit awkward.
80% of Americans believe in miracles. The other 20% have been audited.
I believe you would use this when you get to your vehicle at the end of the hunt or if taking a break during the day. Safer than shooting a practice arrow in the ground. Again, keep it in your vehicle.
Interesting about the safety zone comment. Isn't the crossbow considered unloaded with the arrow removed from the rail? Similar to a muzzleloader with barrel loaded but no powder in the pan. You can carry it in a vehicle like that.
