Another reason to practice at your hunting ranges is to make sure your gun is in order. This just happened this weekend. I spent Saturday initially sighting a gun known to be accurate with a used scope at 50 yards before heading to the range today. I find possibly a defective scope or a bad mount, brought upon by a POI variation between 3 and 9x while shooting at 200 yards. Now its time to address the problem. A rare occurrence that wouldn't be very noticeable at close range, enough to inhumanely injure an animal, brought to light by sighting in at longer ranges. Enough said!!!!
