My browning LR has a much longer magazine length than yours (3.616) and I still have to jump a long way. I loaded up some 212 ELDX at magazine length and found a speed node with 8133 at 2960fps with a ES of 4fps. Then loaded 10-sets of 3 cartridges each 3-thousandths shorter. I found the sweet spot 20-thou under mag length.
