What is the maximum distance I should shoot? I have about 40 lbs of KE and can groups 2" out to 40 yards now. I have practiced my butt off and worked those 30 yard groups down to 2". I realized that 20 yards and 40 yards is the same shot but with different pins which made it easier. What distance would you recommend I shoot at? What is the maximum distance anyone should ethically shoot at a deer? Thanks
