Takes a few minuets at the range. I used to use big cardboard boxes (fridge and washing machine boxes) with water ballons tacked to them at 50, 75, and 100 yards.
We kids did it for the sake of competitive bragging rights, but I bet it'd work here too.
I had to raise my Marlin Model 25 up about 3 or 4 inches ( maybe more?) with the standard velocity"milk carton Wally-World .22's".
