To be honest I have tried this and it dosn't produce any better flight then when I didn't. the only reason I do it is to make my broadheads nice & neat in my foam quiver insert! <img src=icon_smile_big.gif border=0 align=middle> I think what happens more often than not is that the insert was a litt out of whack & by turning it it got seated better which yielded the better flight.
