RE: Does Kinetic Energy = Penetration?

The arrows that my friend used were not 29" long.They were 28" long and the spine was perfect because that was the first thing I checked.I put his bow in my program and got the perfect spine.
Please don't start that stuff about spines and charts because they are just a guideline and are not always right.Close,yes but not perfect.
My friend is not using an Easton arrow and I don't know why you made that assumption.For your info he is using an orange Nitro Stinger at 27 1/2" with 4" AAE vanes with full length EZE crests.They are tipped with 100 gr heads and the inserts weighs 24 grains.I believe the actuall weight was 396gr.Yes I rounded up but big deal.It was easier to type.Foc is 12% and they fly like darts.
This is the same arrow I hunt with but I have unibushings installed with 3" vanes and EZE crest wraps cut down to 6".I use a 75 gr point and get 11% foc.They weigh in at 360gr.
I am very competant with arrow selections,more so than most.That is why about every night I have people coming by to get their hunting setup ready.
It sure looked to me as if you were saying that I was lying and I sure don't appreciate it.If not then I am sorry.If you go back and look you will see that I wasn't sure about the arrow but I know it was either a 2413 or 2314.You can see why I may not remeber for sure but I know what I am doing and have done enough to no what the right spine is or isn't.
