[QUOTE="MagnumManiac, post: 974721, member: 10755"] What Mike is getting at is that a ladder test is run at somewhere further than 200yrds, and the aiming point is only one, not several. What you are doing is simply shooting groups with each powder charge, not a ladder test. After finding an accuracy node with the charge weights tested, the charge that produces the smallest group, as you have done at 100yrds, you then proceed to test that charge weight, and 2 below and 2 above in .5gr increments. Aim at a single point on the target, and see which powder weights group together. This is called the 'node' for that combo. It is also referred to as the OCW (Optimum Charge Weight) method. You can refine this by repeating the node weight and adjusting seating depth in and out. What you have done so far should be ample for a hunting rifle. Cheers. gun) [/QUOTE]
