[QUOTE="ColoYooper, post: 1206928, member: 64765"] You clearly have a "shooter" there in your rifle, but like a lot of us you probably want to take it to the next level. The Ladder Test finds that sweet load that for a 100 reasons you have a round that is a bit hotter than the rest (due to extra powder, increased neck tension, lighter bullet, heavy primer, warm powder...) the bullet will leave the barrel on a correctly Ladder Tested rifle as the harmonic oscillation as at the bottom of its ring, but because it is hotter, it just happens to shoot high and land with the rest of the group. Conversely, a slow bullet will leave the barrel at the top of the harmonic ring and automagically self correct to land with the rest of the group. As previously mentioned, this test can be successfully performed with a 9x scope and some wind...(note my groups always show some horizontal separation due to wind, but it's easy to find the nodes.) OK...On Occasion it was "easy" to find the nodes. A majority of the time I repeated the test multiple times increasing, then decreasing the loads and it was often like reading tea leaves to finally determine conclusive nodes. I then select the middle charge for that node, and work on my form. [/QUOTE]
