Making simulated distance targets isn't too hard when you think of it as a ratio.
If you want to shoot a 12 inch target at 400 yards, but you only have 4 yards in which to practice, you want to solve for the size of the target at 4 yards.
As a ratio, this looks like this (all measurements in yards)
Target size Simulated size --------------- = -------------- Target distance Available distance .333 X ---- = --- 400 4Which we solve by criss crossing the equation;
400 * X = .333 * 4 400X = 1.332Get the X by itself by dividing both sides by 400...
400X / 400 = 1.332 / 400 X = 0.00333So a 0.333 yard target at 400 yards would be 0.00333 yards (0.11988 inches) at 4 yards. The numbers here are round enough to check ourselves to prove the method works. A 0.333 yard target at one hundredth the distance is one hundredth the size.
Grab your calipers and see if you can achieve a clean break with good follow through to confirm hits on your simulated targets. Obviously, this training doesn't account for bullet drop or wind, but we're focusing on your fundamentals.
