[QUOTE="CA48, post: 1511193, member: 21446"] When tuning/trueing ballistic apps with actual drops sometimes to make it all line up I will have to increase/decrease velocity's and BCs. I think a lot of this comes from the weight of a rifle, bi pod being used, and how much a shooter preloads their bi pod. I tested this once by switching bi pods then shooting for drops. Each bi pod required a different amount of elevation adjustment to hit the center line of my steel plate vertically at 750 yards but not by much. I also noticed the heavier the rifle the more drops matched with the advertised bc and velocity from my chronograph or that it took less tuning from advertised bc's and velocity's chroned. I state this because sometimes it may seem like manufactures aren't advertising an accurate bc for a given bullet but really there is more at play as to why everything might not match up as advertised.
