I don't use a peep or a release, still use aluminum arrows and shoot 125 Thunderheads...Using a release takes away from bow hunting in my experience, just isn't natural...Sure, you can get plenty accurate with finger shooting to kill deer...

I'd get a broadhead target and tune your bow for broadheads now...I don't shoot but one arrow at a time as I cut feathers and split nocks when shooting multiple arrows to the same spot...
