i have went through 2.5 dozen axis arrows in the last 3 years adn i couldnt be happier with them. they are perfect for everything (except target only). they fly straight and consistant and hit hard. i have never had one bad experience with them. i would venture to say that i have shot 5to6 thousand times with axis arrows and have never had an odd failure. i did have an fmj completely get destroyed in my target but it hit an insert that came out of another arrow. i actually just bought 6 nanos today. havent shot them yet but i will tomorrow. while i was in gander mtn waiting for them to put the inserts in i shot the range for grins and giggles and actually split one of my regular axis arrows. guess it was a good thing i got some more lol!
