Default Re: So I Wuz Thinkin' About Bore Sighting...

So... I was trying to figure out ways to make it even simpler. I can. How about just ONE arithmetic operation - multiplication.

Looking at the constant - 0.33 - and the fact that I was using FEET instead of yards, (because I wanted precision), but then going back to yards, I realized that one can eliminate the constant completely. In other words, you can drop the 0.33 constant, and just multiply the bore diameter by the range IN YARDS. For example:

.308 Caliber bore (.300), times the range IN YARDS (33) = bullseye diameter in inches

.300 x 33 = 9.9

Which is identical to the number we got in the original post. I don't think I can make it simpler than that.


PS - This of course also simplifies the equation for determining the range at which to set a target with a fixed bullseye size. Divide the bullseye size (in inches) by the bore diameter. The result is the range at which that bullseye will "fill" the bore. For example:

5.5" / 0.168" = 32.7

5.5 equals the bullseye diameter of the target in post #2,
0.168 is the bore diameter of the .17 caliber, and
33 (rounded) is the range in yards to set the target to 'fill' the bore.

Be nicer than necessary.
