Note: this post is not directed to anyone in particular but to everyone in this thread. Please don't take any offense as none is intended. My only concern is to help us use the proper terms so that we can talk to each other and understand what everyone is trying to say. I'm only talking in here about the difference between accuracy and precision. There is a difference in these two words that many either don't understand or get confused and use the terms interchangeable which confuses people.
Precision is not the same as accurate. You can be precise and not accurate. If you hit the same spot over and over again then you are precise. But that spot may not be where you are aiming at. Then you are precise but inaccurate. Say you aim at the bulls eye of the target and keep hitting about 6" high with every shot. Each shot is touching the others but still 6" higher than what you aimed at. You are then Precise but Inaccurate
Now if you shoot at the bulls eye and miss with every shot and all the shots are all over the paper in different places then it's said that you are both inaccurate and imprecise.
If you hit the bulls eye with every shot you are then accurate and if all the bullet holes are close together inside the bulls eye you are accurate and precise.
Precision is not the same thing as accurate.
If you are accurate then you are hitting where you are aiming.
If you are not hitting the point where you are aiming then you are not accurate.
It does not matter if you are shooting at a target 10 yards away or 1 mile away. The definition of precision and accuracy does not change.
Too many people use the word Precision inaccurately.
If you are shooting with precision that means that your groups or tight. But that does not mean that they are accurate. You can have all your shots miss the bulls eye or the target and all land in the same spot where you were not aiming at.
Now if you are shooting at a target and have to adjust the dials on the scope or use the mil dots on a scope reticle to get hits on a target that's far away that's a different topic all together. How you get the rifle to shoot accurately and hit the target is a different discussion. But you are not trying to be precise. You are trying to be Accurate and Precise.
Precision = repeatability. Accuracy =hitting what you are aiming at.
I think a lot of people use the term precision in different ways. I like to add one more term. Resolution. The ability to resolve an image depends on the magnification and the quality of the glass among other things.
I think when people talk about precision shooting they are trying to say that they want both precision and accuracy.
Sorry that I added those to Old Turtle's post as I was actually trying to post this in response to another poster. I guess I didn't do a good job of explaining that at the front of this post.
I come from a QA back ground which is why I wanted to add this about the terms precision and accuracy. I guess I should have made this post a new thread.
