[QUOTE="goodgrouper, post: 185874, member: 2852"] Wind will be a factor at any range but it is easier to distinguish it's effects at 100 yards than at 400. And it doesn't matter if your shooting 300 grain smk's or a 120mm cannon, wind affects everything. When I speak of internal ballistics, I am speaking of each individual component's role and the rifle's role in getting the bullet out of the muzzle. Primers, powder, charge, brass, bullet, barrel, receiver, lock time, etc. all have influence on how the bullet is launched. Using a chronograph and knowing how to "read" what it is telling you can tell you more about the load by a factor of 10 than any ladder test can ever show you. You will see nodes and peaks of accuracy, effeciency, and combustion. Team this information with grouping at short range and you can quickly find something to try at long range. Chronos are the most valuable tool to load development to come along since the introduction of the components themselves. [/QUOTE]
