NAP 100 gr. Thunderheads.
I am no expert I have only shot two birds. I watched several youtube hunts and it seemed like alot of lost birds on body shots. I also saw that some shots were to the neck area and birds went right down. Both birds I shot I hit in the neck. One went 40 yds and flopped the other dropped in its tracks. I figure if I hit them in the neck dead bird if I miss it should be a clean miss and no harm done. I also must say that with my crossbow and my knee for a rest I can consistently hit a 1" black dot at 20 yds.
