I recently went to the range with my cousin, he has an old SKS, nothing fancy. He never zeroed it, so we went to the bench and started at 100 meters, I forgot how fun it was zeroing with iron sights, first time I zeroed a rifle was in the Army, an M-16 A1. With all the optics available today it has been awhile since I iron sighted a target, I was a little rusty but it is kinda like riding a bike. I'm sure people would agree that keeping your weapons especially rifles, zeroed is a good idea in case the optics get damaged and are inoperable. Anyways it was fun even though the range had a maximum of 250, after some adjustments we had nice grouping on the targets, numerous consistent head shots, now if I can control my breathing and trigger squeeze, I might get better.
