My advise, toss the QAD’s and shoot something else, there are a lot of better flying heads than the full blade exodus. I personally couldn’t get them to group well enough for me and sold mine. I was also shooting 300+ FPS at the time and after 50 they just wouldn’t group. The bow was tuned well and bare shafts flew with fletched, maybe it was because of the speed of the arrow IDK, reguardless I’ll never buy them again.
There are a pile of good flying fixed heads out there, even if a lot of people have luck with the exodus, the full blade version is not as forgiving as a lot of other heads. The best flying heads have less surface area, normally those are COC 2 blades with or without bleeders. Kudu, IW, Magnus, Day 6, or similar.
Before you go messing around with your bow give another head a try and see how they fly.
As far as expandables go, I would shoot a good quality expandable for deer anyway, more forgiving, better blood trails and quicker kills. Even the best flying fixed blades are more effected by poor shot execution or wind than an expandable and even the best archers can have a shot break down when buck fever sets in.
In archery confidence is key, shoot whatever you end up shooting accurately all the time. You want to know you can make a good shot at the moment of truth. If you’re not happy with something change it, practice a lot and go hunt.
Most the people constantly on these archery forms including myself are anal about their bows, fine tune everything and mess with them all year. But, the large majority of archery hunters go buy whatever bow their shop sells them with whatever arrows and they go kill deer and elk. Out of the dozens of successful archers I know very few maybe 5% or less tune their own bows, have ever heard of bare shaft tuning or have broadheads flying with field tips. Most just sight in for broadheads and practice with them and go kill stuff.
If something doesn’t work, change it, owning and shooting a new bow should be fun, not frustrating, if you can shoot 3” groups at 60 you’re shooting very well. Find a head that flys for you and go enjoy shooting. Don’t let all this stuff get into your head and make you think somehow there is something wrong with you or your bow.
