In the past two weeks I've been asked to help track two bucks shot with Rage 2 blades by two different guys, we couldn't find either of them. I can't speak for the shots as I never saw them, but one was a pass through from lung to liver, the second was straight into the shoulder with very limited penetration (he guessed 2-3 inches) we never found the arrow.
The first had very limited blood from the start (we waited 4 hours), we made it about 300 yards to an alfalfa field and lost the track he only stopped 2x and never laid down. Three other guys went back and did a grid the next day. I believe this was a non-fatal shot, so the broadhead was possibly not to blame.
The second had great blood (lung)for about 80 yards,then just specks here and there. Ended up going about 1 1/2 miles over two days on this sparse track. He crossed a beanfield that had been cut during our search. Gridding on the other side brought nothing. Bad shots? Coincidence? Bows not tuned properly? I'm not sure, but it does not improve my confidence that this is a great head like some report. I think the inherent accuracy of this (and similar mechanicals) allows some hunters with poorly tuned bows to shoot where their field points are going, but the arrow isn't traveling straight. Thoughts?
