    What I was referring to is a ladder test, where you shoot one round at each charge, aiming at the same point. What happens, is more powder equals faster bullet speed equals higher up on the target, effectively climbing a ladder. If you do it correctly, you'll notice a few rounds cluster together vertically closer than the others, that is effectively a "node" and where your rifle will be most accurate, because the muzzle will be at the top (or stopped) of a node in a sine wave pattern from the harmonics of the barrel. Everything I read about this said start at 200yds and work out 100yds each iteration.

    The longer distance you shoot, the longer the ladder will be which presumably means the nodes will be easier to spot.

    That's actually a very good explanation. Thank you. Yes, I'm a noob.

    Yea, me too, at least to precision shooting/reloading. There is a lot of debate online whether Ladder test, OCW (optimal charge weight), shooting for groups, or using a chronograph to get single digit StdDev's is the most precise way of determining the best load data for a rifle. That's why I asked. I want to start testing loads for my rifle so I can start reloading at that charge to have ammo on hand, but wasn't sure which is the smarter way to go about picking that load.

    Yea, that's what I've been looking at for the correct method of the OCW test. But this link was making me question which is a better method:

    It seems to me that reducing STDEV would be "a" best approach assuming one knows the rifle's inherent accuracy. This eliminates shooter error and besides it's all up to god (physics) anyway after the bullet leaves the barrel.
