Good Accuracy. Bad Precision.

[JFrank]

Sounds like trigger control

I recall posting this during the derailing. Lol

 

[Steve S.]

On the official Kamala Harris web page, she defines “accuracy” as impacting your intended target and “precision” and being consistently accurate. How can anyone disagree with that intellect?

Spend time dining out in the South and you might be asked what kind of “coke” you want with supper, and “Pepsi” is a legitimate answer

This is true, however…

Pepsi may be an accurate answer, but precisely no one in the south drinks that yankee swill.

Do a google search [precision vs accuracy] click "images" for the images related to that search and you will see heaps and heaps of pictures using targets to illustrating a definition that matches what Varminterror said way back in post #2 of this thread. That definition of precision and accuracy is pretty common across many technical disciplines including shooting and shooting is a really common way to illustrate it.

 

[Atavar]

you need precision tools to measure accurately .

And accurate tools to measure precisely

 

[Varminterror]

This is true, however…

Pepsi may be an accurate answer, but precisely no one in the south drinks that yankee swill.

I haven’t had a soda/pop/coke since 1994, unless it had rum involved, so in NOLA this week, I drank Sweet Tea - and appreciated that when I asked for “tea,” the “sweet” part was implied.

Folks are often happy to be wrong. But such doesn’t make them right.

Even when dead wrong I am still Wright and I have documentation to prove it.

LOL !! Thanks guys, I think this thread has sufficiently been derailed!! I do appreciate the participation, though. Glad I could serve as a springboard! In doing some dry fire practice today ( no worries, used expended brass from my previous range trip ) I noted a lighter trigger pull by altering slightly my finger position on the trigger. Seemed to hold on target better with no gun movement. Also, I found that I could turn one of the action screws WITH MY FINGERS it was so loose! Snugged it down. Hopefully my zero isn`t too far off but this needed to be found!

If it is any consolation my Savage Model 10 223 is more Accurate and precise than I am. If I could ever put the two together I would be truly scary.

Good to hear you found a couple things this last session!

I have seen the two qualitative words describe lots of different things. Why they are pretty much useless as a description of just how accurate or precise something is.

A football coach would think 10 out of 10 foot balls going through a 15” hole of an old tire at 50 ft to be amazing accuracy and precision. A machinist is going to be thinking thousands or “tenths” (of thousandths) of an inch. So unless you add in quantitative values, you are making the reader guess what you mean.

The text book definitions lay it out pretty well.

pre·ci·sion
/prəˈsiZHən/
noun

1. the quality, condition, or fact of being exact and accurate.

ac·cu·ra·cy
/ˈakyərəsē/
noun

1. the quality or state of being correct or precise.

So we should revamp the old saying to be, only precision rifles, with accurate sighting systems are interesting.

or would that be

only precise and accurate rifles are interesting.

Darn, I give up

 

[jmorris]

^You could say it either way and no one but yourself would know what you really mean without quantification of the two words.

Ironically with quantification neither word is needed, let’s take the OP,

Accuracy at 100 yards has been acceptable to me, averaging sub-MOA, but precision, well, not good. A general pattern seems to be low and left.

And quantify it.

My firearm averages .750” for 5 shot groups but the centers of the groups are 1” below and 1.5” left of my point of aim. My optic is graduated .25” per click at the same 100 yards my groups were shot. How many clicks over and down do I need to match POA with POI?

If the thread was started with detailed information like that, it couldn’t get to 3 pages, might not have been started at all with the information at hand (as it’s obvious that case would need 4 clicks of elevation and 6 clicks of windage) but we would also have less to do on a cold day…

may i add follow-through to your list of things to try. a lot of shooters move more than just the trigger finger when shooting. pretend being a statue when pulling the trigger.

luck,

I will say at the range one day a lady asked to shoot my BA stealth. Now, I had just put 3 sub MOA groups out at 100 that were also accurate - on the bull.

she shot 3 rounds jerked all three and only hit paper with 1.

the shooter can make a significant difference.
