Pardon what may well be dumb question's as im still a newbie. Firstly am i correct in understanding that a drop chart is a charted trajectory ie X drop at X distance thus allowing you to range find and then accuratley adjust your scope. Secondly would it be unique for each load or is the load just going to affect the distance travelled. (by load i mean differing loads in the same calibre, am i wrong in that) Thirdly how do you go about producing a drop chart. Thank you
