For service rifle dry fire practice I need to print a black dot that will approximate the aiming black at a real match.  I will be at dry fire distance of 10'.

I figured .217 inches but not sure if I'm correct..

How big is the bull at full distance, then do the distance ratio and multiply the fraction times the original diameter  Got that?

Quoted:
36"@600 yards..



600 yards is 1800 ft.

You're shooting at 10 ft., so divide 36" by 180.  0.2" is what I get.

(That's some mighty tiny!)

0.2 inches at 10 ft.


ETA:   Heck!  I'm too slow.

36" @ 600 => 6" at 100 => 0.6" at 10 yards => 0.2" at 10 feet?
