Deal is, I shoot a Hoyt Maxxis with a 30" draw on 82 lbs. of draw weight. Obviously, it's freakin throwing them out there. I've been using the Easton FMJ's for hunting and targets. When placed on the chrono I shot 305 fps. I was also a little under spined. Now I've taken on the role of shooting the heavier 300 spine FMJ(extremely heavy). I know that should penetrate an armored truck BUT do you think I should go with a smaller weight same spined shaft for more speed? Any input welcomed! Also I'm hunting whitetail, hog, and smaller game only.
