On the indoor range, it's clearly marked. Other ranges are guessing. I did just learn that running it to the end of the wire is 15y, though.
Dot Torture is designed for different difficultly levels. Beginner is 3y, then 5y, then 7y, then 10y.
Bill Drills are also often done at 5y, 7y, 10y. Closer in and you don't need your sights or much recoil control. Further out you need more of each.
Now, with all that said, I shoot at a variety of distances, from contact to 85y with handguns. 85y is as far as I can shoot on the police range without a spotter. 115 if you have a spotter to keep people from walking through an opening while you shoot.
Something like this, I'll shoot at 7y:
The goal is to see how much sight picture you need. You need to slow down and be more careful as the targets diminish in size. Learning that instinctively helps you know how fast you can run at a given distance for a given target without throwing shots. Hit the 1" sq, then the 2" circle, then the 3x5 card. The first shot will need more time, the last shot much less time.
This was shot at 15y, although I thought it was as 12y (remember when I said I just learned if you run the target all the way back...)
Basically simulating a head shot. 1" square and 7" circle.
And some bull's eye work (ignore 12y, again...just learned....)
(fingers are covering some earlier holes from revolver shots, not cheating on the group size.
And 15y with my new target revolver.
The first group of 5 shots was 2 and 1/16th inch, center to center. Again, 15y, not 12y as written. I started having anticipation issues and pushed the gun a bit, resulting in some low hits as I kept going. This was stemming from setting off a .357 in a small cubicle in an indoor range. Even with ear protection, it was loud, and I was starting to exhibit a startle reflex, which caused me to shove at the gun just enough to dip the point of impact 1-3". Got my flinch back under control and was good to go from then on.
