[QUOTE="rcoody, post: 1287742, member: 91090"] Well the Optimum Charge Weight system is really the.first step. What you are.looking for are 2 or 3 charge weights that shoot to the.same point of impact. You ignore the horizontal and look for.the least vertical dispersion. This will give you an accuracy node that might be 0.3 gr or more wide. At this point your charge weights can be anywhere in this range and be accurate. Here is.a pretty good explanation.
