Key word being "I" ... not the guns fault. That's the beauty of shooting an accurate gun... when the bullet doesn't go where it's supposed to you get instant feedback on what you're doing wrong with your own technique.
OK, thank for the info. I now understand that your guns shoot 1/2 MOA through 1000, but you don't. I've not heard of nor read in print such accuracy issues explained that way before. But I would like to find out how the rifle's been proven to shoot 1/2 MOA through 1000 yards when you don't hold and shoot it well enough to break all your shots inside 1/10th MOA.

I just don't hold 1/2 MOA at 1000 every time, 100% of the time like you asked, although I have done it quite a bit. Enough to feel confident that my rifles are capable. Is the standard definition of accuracy out to a given distance only based on 100% success? If that's the case then by all means my guns are not 1/2 MOA guns at 1000, and by definition I could then really only claim that they are maybe 2 MOA guns at 100 yards at best.

But I sure am happy with them especially my 338wsm! I thought others, especially here, would enjoy hearing about a gun that shoots really well and share some of my experience for how I was able to do it.

Changing primers always helps me.

Re: Top three things to reduce ES and SD

So just how accurate are chronographs?

Sounds like lots of people put 100% faith in the data they spit out. How accurate would they measure one kernel of Varget velocity difference?

A powder type and load that fills the case.
A target quality bullet .
Precise neck tension from case to case .

The only one I trust completely is the Oehler 35p because it's basically 2 chronographs in one. I suppose you could use 2 chronographs from another mfgr in line.

While it's adjustable, the default for the primary chrony is 4'. The proof chrony is at 2' (in the middle). When you shoot, you get a reading from both the primary and the proof. If they're within tolerance, you're good to go. If they're too far apart, an * prints to the right of both readings and that reading is not in the calculations of ES, SD, Max, Min, Mean.

Again, you could do the same with 2 chronys, but you'd have to make the comparisons manually.
