Man I'd start a bit lower. Probably 59 grs going up .3 gr each. By 61.5 grs I'd bet you find pressure signs. Am at 3178 fps with only 58.7 grs.RL-16 is what I'm planning on using to start load development. Here is the ladder I'm going to use to find signs of pressure:

By only going up .3 gr, you can try to find a speed node to start your seating depth test with while finding pressure, kill 2 birds with 1 stone.
I hate pulling bullets, so I tend to stay on the lower nodes.
