A permission of mine is being plagued by pigeons consuming and pooping in his feed. If you can get within 50 yds one shot and they scatter. They go to tall trees and wait until you leave. Instead of at 50, I zeroed the Profit for !00. With standard JSB Hades and my laser range finder I went back out and at 100 yds got lots of feathers and after I figured the wind out dropped 3 to the ground. With the RTI and the large carbon fiber bottle I get lots of shots. Silly birds don't spook as much when I am hiding in the milk parlor 100 yds away.
