never considered it tfox....
but i KNOW i have experienced the same thing...ive burried my shaft into my BH target and my bag many times upto the blazers...very rarely past them...
but when i shot feathers, they zipped through...usually trashing the feather which is part of why i quit shooting them...i loved them but couldnt stand them ruffled lol...but alot got "shaved" off as they passed through and i beat them beyond belief or chance of revival in short time...not just due to pass throughs on targets either...
only deer i shot was with blazers....arrow blew threw into the glacial till type soil of the north woods...though ive seen it on shows as well where a shaft stops at the fletchings...always vanes...
hmmmm guess thats potentially one more item to add to the list of things that contribute to a pass through...
"but if you line your blazers up with your broadhead blades they will pass right through the slices of the blads..." im going to beat someone to it.......lol
