I regularly practice at these distances in the following order, 40,35,30,25,20, the maximum I practice is 40 yards. I will probably never shoot anything out to 40 yds. because I hunt hardwoods here in Western Kentucky. I don't have any problem shooting close groups out to 35 yds. but when I go to 40 yds. it loosens up a little. I have decided that if I have a really good shot out to 35 yds. I'll let'er fly but will probably only shot from 30yds on in. Good Luck.
