I would add that it depends on 'velocity' (time to target). I wouldn't test my slow revolver cartridges out to 300 yards....At 100 yards, the time of flight is too short for gravity to act much on the bullet

That's kinda sorta what I do, I find that adjacent charges (+/- .2 grs or so) that have very close to identical SD/ES will also be very close in velocities. Have you observed the same thing and if so do you think there is a correlation?is nobody here using the chronograph to generate velocity ladders to look for flat spots?
The OnTarget TDS is good software. The ability to virtually overlap multiple targets increases your statistical certainty without making you shoot so many rounds into each group that you can't distinguish the individual holes any longer.
That's a bummer about the Kongsberg not exporting. Doesn't it log data for the match director at least? I should think they'd want that in the off-chance of a record being set.
I almost pulled the trigger on the Shot Marker, too. Since you've already got one, I am interested to hear how it does. In particular, I am interested in its POI consistency. It says, in a typical frame, you get 2-3mm of possible error. It doesn't say if that is unilateral error or plus and minus error or if it is a fixed offset error or a varying error. If the latter, it's only good to a quarter of an inch at 100 yards, so I would consider it a 200 or 300-yard and beyond device and would still record paper at 100. If it's a fixed offset, then bullets going through the same hole at 100 will still be reported as such, even if the exact point of impact on the paper is off by an eighth of an inch (a big "so-what" situation for load development).
Anyway, I am looking forward to your evaluation and would be interested to learn how closely the tablet target image and the actual target compare
If you have remote wind speed measuring spread out over the range or else very steady wind condition
