A lot farther than I am willing to try, the wind, distance judgement if you dont have time to use the laser range finder,make it more difficult than is practical. I like to do some target shooting out to 240 but I limit myself to 175 area. One of the reasons for that is the trajectory; I sight in 2 inches high at one hundred yd which puts me dead on at 125 2 inches low at 150 and about 6 low at 175. I can hit the 18 inch gong real regular at 240 my longest range but by shooting it I have found that the wind judgement with any breeze at all is real tricky.
If you sight in right and shoot it till you can keep a two inch group at 150 then in a lot of the country you won't need to shoot any farther than that anyway. Lee
