I got exbal last fall and everything was great I was breaking milk jugs to 900 yards. Im shooting a sendero 300 win sending berger 215s at 2960. So there has been a coyote in a field ive been seeing about everyday eating on a dead cow. I ranged the cow at 783. So I took my rifle out found a rock at 780 entered the new weather data in the exbal dialed and shot a 4in three shot group trouble was in was two feet low?I rechecked everything was good took the rifle to the range to see if my zero changed it hasnt i'm not sure whats going on. Im running h1000 so it shouldnt he to temp sensitive. The temp has changed a bunch though from about 60 last time i was spot on with exbal to 11 this morning pressure was diffrent to. Am i doing something wrong?
