[QUOTE="Buffalobob, post: 110016, member: 8"] Brown dog Correct If one assumes the gun is zeroed at the center of the coordinate system ( y is vertical and X is horizontal) and one neglects second and third order terms and the range is the range of the scope zero. At zero degrees X = 0 and Y= 0 at 90 degrees X = 300 and y = - 300 At upside down X = 0 and Y = -600 at 270 degrees X = - 300 and Y = - 300 This assume the equation of a circle with a center at X = 0 and Y = -r Equation is X^2 + (y - r)^2 = r^2 where X = rsin a and Y = r cosa I have to go run some errands while it is daylight but I might have a minor misrememberance in the y term. It should be the same as what Gustavo put up once you get terms and assumptions the same. Don't worry about Jimm, I have filled his head with dreams of a new gun that will shoot faster than light and distances that reach infinity and the brass never needs triming and the barrel never wears out. His stomach will be allright once Roy sends him some bread pudding. [/QUOTE]
