guys,I used brand new bales and set one vertically so arrows would hit in center, not close to wires.At 25yds.I could see clearly that the heavy 300 shafts were flying perfect, slower so my old eyes could see.Before rain yesterday I tried same test but on a new broadhead target and got same results-lighter shafts penetrated 2" better than heavy ones at 20 yds.both seemed to fly perfect and as stated, I could see the slower heavy ones better.Glad you guys took an interest in my ramblings!By the way my 340 fmj have taken 18 deer and two coyoes and have only kept 4 shafts in the animals-two opposite side shoulder hits, one behind ribs and a head shot coyote!
