I had access to a SAAMI pressure test barrel/ballistics lab while doing my load development and ran 3 rounds through it out of curiosity. SAAMI spec chamber, and load matched what I posed above except it was 48.0gr of powder. NOT officially published data that represents any company or organization, use at your own risk, follow proper reloading procedures, YMMV, etc...
What I found was that SD's have a tendency to grow as you start compressing the load. It was interesting to read in the other posted link that someone else also ended up around 47-47.4gr for their optimal MV/accuracy node. In my rifle there is another node around 48.5gr but it was not consistent enough for me. MV was awesome, like 2830fps, and showed now obvious pressure signs, but I decided to back it down and keep it modest.
