My father has very bad shoulders and can no longer pull his bow back. He's in the process of getting a disabled/crossbow permit for michigan. He recently purchased a Barnett Rhino Quad limb crossbow. I'm going to sight it in for him and he'll be practicing for this season. He's been bowhunting for 40 years but we have no idea about crossbows. Where should I place mole skin to quiet it down? Or should I put any period? I've been reading that 100 grain broadheads are the way to go so I'm going to set him up with my 100 grain Muzzy's. Also it came with a BSA red dot and arrows. The arrows look a little cheapo, they are barnett brand, should we purchase easton etc? Is this crossbow decent for hunting. He's going to continue hunting 20 yds broadside shots and he hunts mostly from box blinds, again because of his shoulder trouble he really can't climb trees.
