[QUOTE="Trickymissfit, post: 658779, member: 25383"] My first thout was the the data inputed into the equation was in error. But also you have to remember that the B/C often is close but never perfect from the manufacturer. Also I'd be running the rounds thru a couple chronographs to compair readings (really need three). Plus the equation used to figure the trajectory is not perfect. It has only been worked very recently by a kid in Germany, and you only came out .67 MOA off. So if you velocity was off 50fps and the manufacturer was off .05 on the B/C you have bad data going in. Also were you shooting on level ground? Even shooting slightly uphill at 800 yards will cause the point of impact to come in low. If it were me I'd add another three clicks in elevation and start over. gary [/QUOTE]
