Did some reloading for Rambo this morning before the boys went to the range & Jono asked if there was anything I needed sighted in while there, so I gave him my Kimber bush stumpy to check & run over the crony, we fuk me this thing normally shoots .75moa, here's the 100m target he gave me :o
Attachment 75558
Looks like he was patterning a shotgun
Rifle is obviously not as good as you thought it was.:D
Thats pretty good for a Kimber!
Hahaha
some would say exceptionally well, was that the 500m target?Quote:

That's at 500 dwarf paces or 100 normal (963 dwarf) ?
Hahahaha yeah as you probably realized, I'm taking the piss @Pop Shot he did a good job and sorted it, that was a target that the young guy in front of em was sighting in with. A 7mm rem mag with no rear bag, vap'ing & drinking red bull while his old man called corrections ( so basically chasing himself round the paper lol ) :thumbsup:
Lol. Was watching his shots in my scope like wtf is he doing. The 500ml can of redbull and vape mustve had him shaking like a mofo.
That little thing shot well. Especially with the 4x scope.

ok so where is your real target?????
Vaping and red bull? Maybe he was trying to recreate the situation of the roar when rampaging stags charges:XD::P:O_O:
If that's really the case (can Never be too sure with Phillipo-could be a double pxxxtake) Then its not too bad. Just shows the fallacy of adjusting on few Shots.Quote:

At least hes put the shots down range and onto paper. I'd rather go hunting with that gun than one that did a one inch group of 3 at the top of the circle. (or 5 hits on a 12"gong at 2oo m.
Its the first one that matters :DQuote:

that's a new one, whats mpi? The one I deal with loves auditing us :D
mean point of impact?
whatever the f that 'mean's. Is it like a gun that shoots good groups but each time somewhere else on the target?
How do you even get a random mean?
Draw a box around all the shots and the center of that box will be close enough[emoji106]Quote:

I know what mean is. Nothing random about it though.Quote:

Keep away from the mean ones Gibo. Find a nice one.Quote:

The theory is that the population of all possible shots has a mean value and each shot has a random deviation from that location.
You try to estimate the location of that mean point of impact from a sample of shots fired on paper. At the same time you are estimating the size of the typical deviation (often we talk about group diameter but its mathematically easier to handle the standard deviation which is the root mean square deviation).
Now, the more shots you fire, the closer the observed sample's mean point of impact is to the theoretical population mean point of impact. You also get more information on the group size.
Groups of 1 shot each are pretty random. Groups of 3 shots are better and usually good enough to sight in with. Sometimes you'll get 3 consecutive shots all on the same side but mostly the mpi will be inside the triangle. Groups of 5 shots will almost always contain the true population MPI within them and you are starting to get an idea how good your grouping is.
So, if someone tries to sight in with 1 or 2 shot groups, they don't know the mpi and they don't know the amount of deviation, so the underlying population mpi will have a lot of randomness compared to where they see the shot fall.
If you're like Phillipo and you already know the grouping is 0.75 MOA then you can adjust pretty quickly to get the gun sighted in within 0.75 MOA by firing one shot at a time.
