    Groupie or Ho' Chaser? Zeroing the Rifle

    Folks,
    I learned back the ancient days when the M-16A1 was new and wheel guns still rode the hips of most police, to zero a rifle using 3 shot groups, adjusting the sights or scope and shooting another group until it hit the proper spot on the 25 yard zero target, then firing a fresh target for conformation. This was followed by firing on the Known Distance range at 200 yards or whatever was available for verification.

    Now I see, even on the TV, people using a machine rest, firing a single shot (after bore scope alignment) adjusting the sights to the point of impact and then verifying the zero with a single shot.

    So, how do you zero your rifle.

    I use 5 shot groups. It's called triangulation for a reason. Fire 5 shot group, adjust from center of group. Fire another 5 shot group to confirm. Never ever adjust sights based on a single shot. Although only carbines are zeroed at 25 yards or 200 yards. Rifles should be zeroed at 100 yrds to make the math simple shooting at longer ranges.

    I use a bench rest and fire three shot groups. I've tried all of the gadgets and have returned to my original method. Bench rest and three shot groups.

    There are only 3 colors, 10 digits, and 7 notes; it's how we arrange them that is important.

    This is what I do as well. Mainly because you're the one who taught me how to properly zero a rifle.

    I fire one round, without moving the rifle, move the reticle to the bullet hole. Fire another round and make the final minute adjustment. One can zero a rifle in 3 rounds with this methodology taught to me through counter sniper training at HK in 94.

    I've also been instructed in zeroing like Bob explains. If I'm zeroing over 100 yrds, I use Bob's suggestion. At 100, what I described works quite well and takes a lot less time if you can zero from a bench and not field positions.

    Used groups for my carbine as Bob describes. Brownie told me of his method learned at HK sniper school but haven't tried that method yet. Put a new sight on my .22 rifle and might give it a try. Will use what works when I pick up a .308 rifle bolt gun or M1A, hopefully one day soon.

    I was trained the same way back in the day. But with modern firearms, ammo and scopes I find I can dial-in pretty quickly with 1 shot per adjustment. Once I get closer to center, I get back to the 3 shot groupings. On a fresh firearm, I get it "on paper" first and go from there. This is actually one of the funner aspects of shooting for me.

    I like shooting so I don't mind firing the extra shots. And when I make my adjustments it normally only takes once.

    How do you do that? Is the rifle in some sort of vise?

    from the previous post, takes a lot less time if you can zero from a bench

    Here's how it works if you haven't vised it and just sand bagged it. Shoot the round, put the crosshairs back on the X you tried to hit, hold it steady in the shoulder and move the turret knobs to till they are on the bullet hole. Now reacquire the X, make the shot. Minute adjustments of a click or two are all that will be necessary. 3 shots and done is normal at 100 yrds from the bench.
