The sled/moving target thing worked out very well actually!

And I did as advised by some by using a target only 2 meters up instead of 2.6 meters up for the one dragged by the car. I also added a 20 liter watercan lashed to the sled to add weight down below, and keep the contraption stable. The target did still wobble side to side as it was being dragged though, so it looked very "alive".

I then got the car to pull it at 35-40 km/h down a private gravel road (with a hill in the backround for safety), and pass by me 1 meter to my right side (no reason to get run over by the car!). The sled was fastened to the car with a 20 meter rope, as having it longer didn't work due to the terrain/road. The 20 meters of rope at that speed gave me just time to get off 2 shots within about 2 seconds, and the rifle wasn't raised, and the safety pushed off until the moment the car passed me. I ended up doing this 10 times. with all shots ending up within a 6-7 inch circle. Besides a couple of flyers that went out to about 9 inches.

I then added to the fun by putting up a second elevated target (the old 2.6 meter high one) 90 degrees, and 10 meter out to the left, so the drill then became 2 shots at
the "charging" target, and then 2 more shots at the one "sneaking in on my
left side". I then did this drill about 20 times (split up between two days), and I plan to continue with more next weekend.

The only "problem" is the logistics of dragging and positioning the sled back in it's starting place, which eats up quite a lot of time.

Even if there might be a better way to do it, it was good practice, and terrific fun no matter what! I can highly recommend setting something like this up, even if it's just for the fun of it!
