[QUOTE="Alex Wheeler, post: 1356343, member: 101859"] So theres a couple things that can happen. For our purposes we are looking for a barrel node and a velocity node that happen at the same time. A harmonic node in the barrel is when your bullets are exiting at a time when normal variables in the load do not effect the groups as bad. There are multiple nodes but where you load in relation to them will make or break them at long range, so we test a little farther out. A velocity node is when you increase the powder charge and the velocity stays basically the same for a "window" [/QUOTE]
