Switched from open sight lever gun then to scope gun and didn't move aiming point and in the blink of an eye, gone
Who doesn't have a chronograph?

Long range Benchrest guys shoot some of the smallest groups in the world, we do not require chronographs to tune loads at 1000 yards.

Guilty. Actually I was lucky as I only knicked one element of my skyscreen. Oehler sent me a new one and several extras. Sad part id I shot it at close range with a CZ52 pistol.
Fortunately with the exception of the actual sensors the electronics are beside me on the bench. I also have some spare sensors, just in case. When I did shoot the slat black electrical tape held it together till I got the parts.

Sunday I was testing cast loads with a new powder. 3" 5" and 16 inch barrel. The three inch makes you really pay attentionGuilty. Actually I was lucky as I only knicked one element of my skyscreen. Oehler sent me a new one and several extras. Sad part id I shot it at close range with a CZ52 pistol.

Not a Crony, but I did learn a lesson once about Oehler 35P sky screens and exactly how far a SKII choke opens up with 7 1/2 shot at 15'.
Luckily as posted above the Oehler guys are very good with spare parts and have a sense of humor.
I have never shot a chronograph in 30 years. I go to extra pains to make sure I don't. That kind of activity is hard on the budget.
That being said, I WISH I had shot my first chrony (Shooting Chrony). Instead, it went out slowly by the dementia route. The info it was giving me wandered off and it took a while to realize what was going on. So, I was making adjustments with bad data for a period.
Some people take care of their tools and some are just plain hard on them
I've had two expire from "lead poisoning".
Both were due to rushing to complete a string like trying to beat a rain storm or needing to get on to the next event.
It is one of the reasons I bought a LabRadar.
My wife is one of the latter. Bless her heart. Unfortunately, I am an Airframe & Powerplant mechanic, so I have an innate desire to fix things. I have a full-time job keeping up with her.

Wrong question for me. Question is how many times did I shoot it? How many times can you hit the wire supports (without trying?) Have you ever hit it dead center on the control panel?
But you have one?

Yes I do have a chronograph but it’s just the pro chrono , nothing too fancy that we use to check fps in several rifles for drop charts etc. or to use for sorting cases per fps rather than weighing its performance based , culling the unexplained flyers a chrono can be just as vital to varify my scale consistency and loading routine or lot number variations of powder or primers. At a set distance like 600 or 1000 yards we tune for exit timing rather than es/sd like a tactical shooter would that engages multiple targets at different distances.
For us we don’t care how fast or what the ES is as long as it shoots small groups.
How you guys do things is really interesting to me. I think there are things to learn from every discipline. For most of my time as a hand loader, group size was all that mattered. It pretty much still is, but most everybody is about long range now, so I started looking at ES and SD just out of curiosity mainly because I actually have the tech to collect that data. I did acquire a long range rifle pretty much by accident, but my main target of interest hunting wise is the prairie dog, so small groups at reasonable ranges are still the goal.
I never did really think too much of weighing brass. Any difference in weight doesn't have to come from wall thickness variations because most of the mass of the case is down in the rim area. I have weighed bunches of brass and stand them up just for fun because it's neat to see the classic bell curve form.
I draw the line at spending hundreds of dollars trying to suck an extra 32nd of an inch off of the groups from a hunting/varmnt rifle, especially since I can't prove from day to day that they aren't a tiny bit smaller just because I am practicing more. That's why I scoff at the accuracy claims of some of the annealing machine manufacturers.

I don't have one and have never used one. Aside from sheer curiosity, I don't understand why I'd need one. If I'm within published load data spec (OAL, charge, bullet), seeing no signs of pressure concerns, rounds are grouping well, and anecdotal evidence indicates I am in the general ballpark of the kind of muzzle energy I was looking for... what's left, really?

I'd be seriously curious as to how many loads you've seen perform well at 1000 that had high ES and SD???

While an ES of thirty or forty would indicate a problem, ES in the teens is no big deal if I’m in the node my rounds are not shifting despite an increase in charge.
So to answer the question - none’ but to expand the smallest es doesn’t always mean the smallest group either.
Here’s a ladder test at a thousand yards with an unknown ED/SD yet the load doesn’t shift.

Pretty much nothing. The only real reason to tinker if you aren't in competition is because you are curious. I tinker because I like the cause and effect of it all. I have a hunting friend who maybe shoots 5 rounds a year, or less. If he has to install a scope or sight in a rife, he calls me just so he gets it right. That is fine too. Boring, but fine.

If your doing drop charts for a hunting rifle, chrono is pretty darn handy.
Do you do initial tests at a shorter range for convenience?
I agree. I like to see what my load will likely do at my altitude.

Just like why would anyone cast a bullet. Well because

Not sure if you're being sarcastic. There are lots of practical reasons to cast bullets -- many of which have to do with the pursuit of achieving an accurate load. I don't see your parallel.
