Rifle POI varries per the shooter??

[mallardsx2]

Anyone ever sight in a rifle and someone else shoots it and consistently group differently than you?

I wear glasses and my wife does not and she consistently hits in a different spot than me with her rifles.

I'm not talking an inch or so I'm talking 8 inches....

I have never experienced this big of a difference before.

I have heard of it of course but we were just testing out her .308 yesterday and at 50 yards 8" seemed excessive.

Just my two cents... When I hand one of my rifles to someone, I always tell them to check the diopter and parallax adjustments, and adjust them for their own eyes. Sometimes they leave the diopter alone, but I expect them to adjust the parallax for their own eyes, and distance they are shooting. Makes a difference.

8 inches at 50 yards seems like way too much difference. I can't imagine what would cause that much of a difference between you and your wife. Crazy.

How a person applies stock pressure, how a person squeezes, and the scope adjustments mentioned above can change impact. I'm guessing one of you has a pull or push tendency at the squeeze but I could be wrong. My wife always hits right of impact from me with her gun. It's only a few inches at 200 yards but it is very consistent.

I experience a similar issue with my son. It is several inches at 200 yards and continue to widen as the distance increase.

Are your wife's shot in a reasonably small group and how many does she shoot in the group?

This is the question that matters. My wife and I shoot our rifles almost identically, but we have nearly identical vision which is corrected with glasses. One of you two is doing something very different from the other. 8" is a mile.

Dominant eye issue? Or maybe using the wrong eye (should be right eye for right handed shooters, left eye for left handed shooters).

 

[HogsFly]

While instructing my wife and her friend via an NRA Basic Pistol Shooting Course, we discovered that while she is right-handed, she is left-eye dominant. Yes, I told her she should be shooting with both eyes open... But when she used her left-eye only, she was right on target.

Here is a related article:

Definitely dominant eye issue

 

[Horsenhike]

How does eye dominance affect a scoped rifle shot? Handguns and wingshooting sure, but a scoped rifle is a fixed set of mechanics. My guess is flinch.

My wife is right handed but left eye dominant. Had her shoot one of my favorite rifles and couldnt hit the broad side of a barn. I watched her shoot instead of watching the target and she was trying to shoot right handed and looking through the scope with her left eye. Had her shoot left handed and that made a HUGE difference.

 

[Horsenhike]

Well obviously that would make a difference. You would ruin all the mechanics by trying to lean over the rifle, and honestly that should have been caught before she ever fired a round.

I practice shooting my rifles and handguns with both hands, and while not as comfortable, can hit reasonably well with either. On a bench with a magnified optic shooting with your strong hand it really shouldn't matter. The article posted above even refers to that fact. I have a couple friends who shoot handguns left eye-right hand. Looks a little odd but they can keep up. Rifle scope off a bench? 8" at 50 yards? Just seems like something else is going on.

Same scenario as my son. Right handed and left eye dominant. It does make a bit of a difference.

X2 seems like a lot

 

[mallardsx2]

She put 3 bullets in a 2" area 8" low at 50 yards.

Mine center-punched the bullseye.

 

[Colorado Cowboy]

I'll bet she has a much shorter neck than you and her head is a lot lower. Her sight plane can change and effect poi. Have her take the rifle, close her eyes and shoulder it as if she was going to shoot offhand. Open her eyes and ask her what she see's (don't let her move her cheek or head. I'm betting it's terrible stock fit. I know 8" @ 50 yds is a lot, but you have to start looking somewhere. By the way that is 16" @ 100...32" @200!

 

[badgerbob]

CC, Just a thought on what you have posted. If the rifle fit is that bad and she does as you suggested, shouldn't she be seeing an out of round scope image? It seems she would be looking through the scope at such an angle, the opening would appear like a football instead of round.

 

[Colorado Cowboy]

That's entirely possible. But my suggestion was to start a process of elimination. Stock fit is the place I would start.

Yep. I agree.
