For a long time I've wondered why people show pictures of targets and groups that miss the 'spot'.
Sure I get the 3 shot grouping, and the measurements between the shots - but I'd love to know why hitting the bullseye never seems to be attained.
Always been too embarrassed to ask...
@
thats the last thing i worry about when doing load development for a rifle, as poi will never be the same, once people fnd the load for there rifle im sure the latter would be obtained
Yep
Obtaining the desired POI is always the last step for me to.
I always try to have it a moa or so away from the point of aim, otherwise your point of aim gets bigger & bigger & making it harder to be as accurate as possible.
This is exagerated by using high powered scopes.
What Greg said, this is why small bore has one shot in each target as well as making easyer to measure. Also plenty of people "zero" 2'' high or what ever @ 100Quote:

P.S. The only stupid question is one that you dont ask!
Damn straight!!Quote:

I always put the bullseye on after I shoot the target:P
haha now that is an awesome idea......
Because most of the time targets are shot at 100m. Most people have some hold over dialed in at that range so that they don't have to think about hold over out to 300m. E.g. with 308 I am 2.5 inches high at 100m which sees me right out to 250m.
Hmm targets that self center after the bullets hit..... if you can make it work everytime you could make a fortune :ORLY:Quote:

Because their zero is likely to be 150+ Say the zero is 200m (Just for arguements sake) depending on the calibre and velocity (Basically) it would make their POI at 100m 1.5" high at 100m (Again for arguements sake) and they would be 1.5" low at 260m (Again for arguements sake) Now what this means that anything under 250m just point at it and shoot and you will be within a 3" circle of where you aimed. No need to dial in. So back to the 100m POI. It is confirmation by grouping at 1.5" high that
1. You are grouping well
2. The rounds/loads you are using are good/bad
3. The POI is correct for this range.
4. You need to confirm by shooting at 250m that your supposed POI is in fact 1.5" low
5. It is easier to see groupings at 100m and make adjustments that is to see groupings at 200m
6 . Any environmental effects are minimised the closer you shoot. Wind, swirlin wind, mirage etc
7. Scope parellax setting if it has one is correct
Its about getting one thing right at a time.
Good groups = good ammo and shooting technique and rifle set up (Its a stinky trying to get this bang on. SO, eliminate 2 out of three. Usually the set up and technique. Tight scope, possibly floating barrel etc. Know your own quality of shooting. If your mate can shoot 1" groups with his rifle and you hop on it and get 4" groups things are looking good. If you pull of a 1.5" groups you a re looking good.
POI vertical difference from the bull = Field knowledge of where your rounds are going at that particular distance.
I would have said if your mate shoots 1" and you use it and shoot 1/2" your looking good :D
Yeah Me too. Actually had something similar happen once, first 3 shots were friggin good so slightly threw the 4th and 5th. Now I can still use his rifle if I need to. Not to sure how it would have been otherwise :thumbsup:
I thought it was because all you cnuts were just crap shots :P
:D
