My arrow is the 485'ish Grain FN Cast bullet leaving the barrel 1750ish. All those "Factory" Heart shot pictures are too low in my book but your Red line, Black dot and Yellow circle match where my PCH or duplex reticle comes to rest on deer or elk. A bit low and I still get the heart. A bit high and I've got Bone flying through the lungs in front of that big Flat Nose. Took the old Girl out a couple of days ago and put 3 in one cloverleaf hole at 50 sitting over sticks, backed up to 150 and put the other 5 just below them in a 2" group over same sticks. Out to 250 or so, it's hold on the middle hair and get the knife ready. At 300 I have to think about it a bit. Wiped the bore with Marvel Mystery Oil on a two patches and hung her upside down on her favorite hook. She's ready.
