This is my target set up. It is an 07 Bowtech Tribute at 55#, 28" DL, DS target sight, 24" stabilizer, V-bars and Carbon Express NANO 630 arrows. ($300.00 dozen) Also was using a 4X lense and peep clarifier.
I actually was on track to shoot a better group the other day and after I saw how tight the first 5 had been I choked on the sixth. The first 5 were in a sub 2" group. The 6th arrow I choked on so bad I missed the group by 8".
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
