Ballistics Ladder Test - Partially successful

Using a Labradar and a Shotmarker system, we did a ladder test for a Remington 700 with two different bullets, two different powders and five variations of each combination in 0.5 gr increments. 168 gr ELD-M, 168gr Amax, BLC2 and RL-15. We got a couple good groups, but also a lot of spread on most of the recipes.
