This is jut my personal opinion but since I don't hunt with practice blades I aint gonna practice with them either. If I am gonna hunt with it then I practice with it plain and simple.

Practice blades are not shaped the same and may not fly the same as real blades.

Practice with the same set of real blades all you want and then spend a whopping $15 for some razor sharp ones. I mean you got at least two months to save $15, I think you can manage that.

Besides that practice blades rip tear your target when passing through rather than cutting nice clean slices.[:'(]
