Which is preferred for tuning/load development; 100 yards or 200 yards?
And why?

200 will show you stuff you wouldn't notice at 100. Alternatively, if you're not confident in your wind reading 100 is the better way to go. Then, there are the rifles that will shoot at one but not the other....
That written and read.....I reckon I don't know....!

OK, if you've a truly accurate rifle it's 'better' to tune at 200yds. Here's why....
"Tuning" in it's simplest sense means working up your loads in such a way that when you're "tuned" you can get bullets of different velocities to print or impact at the same point on your target. Picture this, you're an ambidextrous quarterback, you can pass with either hand, BUT, you throw harder with your left. You're equally accurate with either hand, you can hit 'em long with either hand....but you throw harder, faster with the one hand.
If you watch your video replays you can see that the slower ball arches higher to hit the same target. The fast pass and the slow pass BOTH HIT THE RUNNER but they travel different paths.
Sooo, when your rifle is tuned you've got bullets of different velocity impacting at the same point. Somehow the rifle is compensating or launching the slower bullets higher to get them to the target with the faster bullets....
Draw the lines on paper, two trajectories converging at a single point and you'll see why 200 is better than 100. And separate 100/200yd tunes is better yet. And possibly BEST is loads weighed to eliminate velocity variance... but in the real world this is wicked hard to accomplish without you know how to preload for every range and weather condition.
And barrels burn up fast.
