You are 100% correct Rev!! I mark all my arrows with a number, then and or when I begin to experience any abnormal flights, I note this and put them aside and find out why. Perfect example. I just bought a dz of GT Velocity XT 400's. Cut them. Weighed them. Found 2 that were 10grains heavier then the others. Go figure?!?!?!?

I then weighed the inserts and all was good. My GrimReapers to be used. All good. I took those 2 and cut off an 1 inch and was close enought to put me with in 3-5grains of all total. 345grns average total with 100 grn BH on my electronic RCBS powder scale.
