That,s amazing hiring, 2100 yards even with any type tripod or rangefinder. I'm not saying you can,t shoot that far but funny thing is I just. Watched a war show about Iraq,and Afghanistan. The longest shot ever made was 1 and a half miles on a human enemy.it was in Afghanistan, the guy was a well trained sniper with a high tech 50 caliber sniper rifle.It was set up with all the best scope ,rangefinders ,the work,s.The guy that made the shot,said he has practice shooting,the same replace as the actual shot.It took 3 shots for the kill,and that was with another sniper sporting for him.1 mile is about 1800 yards,so 2200 yards is close to what this sniper did,almost unbelievable. The second longest kill shot was a mile again by a different sniper in Iraq,again took 3 shot,go do this.They even tried going out with retired army personal to practice these 2 shots it has not been repeated as to the date of the film I watched.so it's hard to believe a deer rifle can do close to a 50 cal.
