I read on the orion with the dyna cam that they don't have timing marks because their window of rotation is so wide. My question is, does the came produce the same effectiveness throughout this rotation? Also is there a way to tell if the cam is off or is it even possable to get this cam out of time? Lastly I'm shooting a roughly 350grn arrow, with a draw length of 26.5" and pulling 60#. This orion is rated at 300fps IBO and I'm getting 226, does this seem right? Thanks in advance for any help.
