 Many thanks Chris for the link.

just my 2 cents, inputted info for my 308 quackenbush, told me at fps I was shooting and sighting in at 50 yards table told me at 70 yrds  shot would drop 2.5 inches. well folks, the shot didn't drop 2.5 but a whole six inches. just sayin......nothing works better than spending time on the range to learn how a gun shoots....

Always send a monkey into space first, test the math yes !

I used this at 500, 550 and 615 yards on my 257 Haley 12 oz soda can video’s and always put me within 20 to 30 inches at 600 yards.
