Mean point of impact

[wforider]

Yes I picked up my gun today....Really does feel good in the hand.

Cz gives you a test target from their range for quality control.

On the target has 5 computer circles for the five test shots the gun did @25 yards.

There is a cross hair in the center and a filled in dot which stands for mean point of impact and 5 circles where the computer recorded the testers shots.

What does "mean point of impact" mean...is that a computer average of the 5 shots and thats how the gun shoots?

As I understand the "mean point of impact"; with the firearm's sight picture on the intersection of the cross-hairs, the "mean POI" would be one hole, all other factors being equal (shooter's grip, trigger press, pulse, breathing, wind conditions, person in the next lane breaking wind), with the actual (or computer-generated) holes reflecting the input from the other factors.

I got one of these with my new BD. It didn't give me a "Warm Fuzzy" about my first CZ. If you read it like I did, I saw MY gun shooting high and way left of center. This is NOT what I wanted to see when I opened my new CZ!!!....All that thing shows is that YOUR gun was able to spit out 5 rounds at the hands of someone who either cannot shoot or is just proving to you that your gun did indeed shoot. I took my gun to the range....at 50ft, my gun not only shot 5 times, but in a tighter pattern than what this guy shot.(RELIEF!!!)

Well Matula was the shooter for mine, and had me a bit worried.He got 3 of 5 in a 3/5 square at 25 meters.
Just ran 50 through mine tonight First 5 in the tight ring @21 feet and 5 outside a bit.

I need reading glasses and am guess far sighted, having a hard time sighting up a bit, tried with glass no glasses....may be I need Bi focal s...sucks on the other side of the hill.

I apoligize and edit my last comment for the individual that shot my test page. I shot at 50ft (Max length of range) The individual who shot the test of my weapon shot at 25meters = 82 feet......22ft. farther than my shooting. His rounds are good. Dumb American me. I sounded like a smart ass. If I am wrong, I will admit it...so, I'm admitting my comment was out of place and I was wrong. My humble apoligee.
My CZ75BD is still a kick-ass rig though!!!!

LOL I put what word with American? It still stands. You better come prepared if your posting on in this forum...people do read them! LOL

I don't know where I heard this, but I thought the factory adjusted the sights to the mean point of impact before shipping?  I thought that was the purpose of the test...as well as a safety check.

Most factory test targets are just that, a test.

I can't speak for CZ but Sig Sauer test targets (except for their competition and custom shop pistols) are simply to prove that the gun was test fired and that it functioned. They have several people who do nothing but fire new pistols all day, every day, to make sure they function as designed. The targets are in no way intended to show how well a particular pistol will group or shoot to POA.

If they (or CZ) adjusted the sights on every pistol they made to shoot to POA after manufacture,they'd never get any guns out of the door at all.

  Have to admit also that the test targets that come with CZ's can be a bit disconcerting if you think of them as an accuracy and sight adjustment test. I have bought 3 CZ's so far and all of them require a diffrent sight picture for the ammo I normally shoot. ( Win 115gr FMC ) . My first CZ75B's sights are pretty much right on ...my SP-01 shoots about 3 inches lower and my SS75B shoots about 4 inches to the left . If I switch to Blazer brass it changes a bit. So the factory cannot possibly take into account all these factors plus all the other factors that determine where you hit (or dont hit) the target. The local range has their pistol targets set up at 75 ft...25 yards , and they use wooden target frames. 75 feet is considered by most people to be a fairly long range  and there are a lot of shot up target frames most of the times I have been there. I normally ise a 6 in or 8 in Shoot and See target  which I have to admit looks really small at 75 feet. To small unless you have shot as much as I have and welcome the challenge. Sometimes I shoot good groups, (all 10 rounds in 3 or 4 inches) sometimes I dont. The best thing you can do is to put your pistol on some kind of rest , sandbags work great , and eliminate as many shooting variables as you can. Then you will know for certain how well adjusted your sights are. Once your CZ gets broken in you will be able to really feel when the point of release is and can adjust your sighting just when you are ready to shoot.
By the way Widge..love the moving icon on the bottom of you postings...makes me laugh everytime i see it.
