[QUOTE="Oliveralan, post: 373438, member: 20245"] Roy, thanks for the help. I was getting the exact same thing from my exbal. I could not get the 200yrd drop to fit into the equation. I will do the whole thing again Saturday and measure drops in inches at all the ranges. My scope is 1/4moa and I know the 300 and 400 is rock solid because I was putting shot after shot dead centered on the steel plates. The others I was shooting 3.5" dia clay pigeons so it could be off by a slight margin. I did usual inspect the clay disks to seE where bullets hit. However I shot the 200yard drop on paper so I'm quite sure it's correct. The only explanation is a different BC, or ofcourse I did something stupid (just as likely as a different bc). Of the curve cannot be achieved with changing velocity, the BC mus be off, assuming my drops are correct. Well exbal is dead on for 300 and 400, the two I'm 100% sure are correct. The other drops aren't off by a lot so could just be error on my part. [/QUOTE]
