Does shooting with a partial scope field of view affect accuracy?

Are you talking about not getting your eye centered behind the glass?

If so, and there is any parallax in your scope (not dialed in properly or a fixed objective at the wrong range) you could definitely see some error. This is why a consistent cheek weld is so important...as is adjusting for no parallax if possible.

The situation is that my scope's eye relief will not allow me to see the full FOV with my back pack on (shoulder strap increases the length of pull). So my eye is too far away (scope is all the way back) and there is a black shadow surrounding my view through the scope.

Not sure about parallax except that my scope is for center fire guns and it should be made for shooting at 100 yards parallax free.

So the shooting situation would be for off-hand shots of less than 100 yards. Beyond that, I would be forced to take off the back pack and get into a supported position.

As long as you're looking straight down the middle of the scope, so the reticle is centered, you're good.

Thanks Haxby and Outlaw Man.

Haxby's right. You should be fine if you can get/keep your eye directly behind. Basically, keep the black the same thickness all around.

My question was more in regards to not being able to do that. For instance, if your scope was mounted so high you could only look through the bottom 3/4 of it, or if you had a really short neck and a huge cheekpiece.

I will need to practice my cheek weld with the back pack on to make sure my view is centered. Thanks.

That's a good idea.

Happy shooting.
