1/2 scale target

[ohsevenflhx]

1/2 scale targets are 1/4 size. As silly as this might sound, when setting up a classifier for dry fire, do I use 1/4 the distance from targets?

No, you scale linear distances, so you do it at 1/2 the distance.

 

The area of the scaled target is indeed 1/4 area of the actual target, but that's how the actual target would scale too - dropping with the square of the distance. So, a full target at 5 yards would be 1/4 area size of the same target at 10 yards, but the linear dimensions of the target would still be just 1/2 of it. The same goes when using 1/2 size targets - you place them at 1/2 distance and you are getting correct size and correct area, the former being 1/2 and the later 1/4.

I found PDFs of USPSA and IDPA targets for letter size, which comes out 1/3 scale.  Good for dryfire and I shoot them with a .22 conversion at 5-7 yards.
