Don't get discouraged. There's more to it than shooting a 650 grain arrow, especially for whitetails. THP (The Hunting Public) has several videos where they discuss the success of heavy arrows, but most of them are shooting what the Ashby Foundation chart shows to be a "B" class arrow weight. Which is considered "acceptable" for whitetails, mulies, black bear and antelope.
Personally, I'm shooting 57# @ 29" DL with a 520 TAW. My arrows are tipped with Grizzly left single bevel broadheads and I feel very confident of getting a pass-thru on a whitetail, this fall.
The 650 Total Arrow Weight arrow gets mentioned for 100% pass-thru on hitting bones in African large game animals. African large game animals have hide thicknesses that we don't have to contend with here in North America. Then there's the heavier bone structure of African large game. Let's face it, they're dealing with an entirely different type of large game animals. I wouldn't let this "spook" you off...rather, take in what will work for you and let the rest go.
Well.....the Ashby Report lead me to this lunatic "The Ranch Fairy" and I watched 3 hours worth of tuning videos on YT yesterday by him and THP!! I have no desire to shoot a 650gr + arrow, but I did order the "Ranch Fairy Test Kit" from Sirius, because I would like to shoot a 500gr + arrow. I'm currently shooting a 385gr arrow with a 100gr G5 Montec broadhead. I have had issues with passthrough, so I'm going to shoot some heavier arrows with different spines and see what I can improve. Thanks for the feedback, appreciate it!!
