I noticed, while practicing, that a Grim Reaper 1 3/8" was not flying accurately. This head appeared to shoot alright when I first installed it, but is now not keeping pace with field point/practice heads/ or my magnus buzzcuts. The blades do not appear to be tight to the ferrule, and I'm thinking this may have something to do with the accuracy issue. I am curious if any of you have had the same issue, and how it was resolved. I decided to try Reapers, and I really want them to work. Your input is greatly appreciated!
