I agree.

But, sometimes the best load, especially with light weight bullets, isn't with the slowest powder and a full case. RL-15 is a good 6.5x55 powder and I was using JB's load of 42 gr. with the 100 NPT, just to see what it would do. So, even with a 10 gr. over charge (52 gr.) the case wasn't full.

BTW, this gun favors 139 Scenars above all and Norma MRP seems to be one of the top performing powders. I just happen to have a big jug of MRP, so that's the current hunting load. MRP fills to case enough that a 10 gr. overcharge won't happen.
