If you see some significant/huge increase in velocity, in a cartridge not known for being deliberatly loaded to lower pressures, real good chance you are operating above recommended pressures.
Starting to feel paranoid now!!

I've lloked back over the velocities I've posted in this thread and I don't see anything that looks like a significant velocity increase...

In fact, as I've worked up in 0.5 gr increments from 19gr up to 21gr the velocities shown on the chrono have also been incremental. Even the borderline compressed charge of 21.5gr, which gave me a split case, was not a big leap ahead from my existing choice of 21gr.

I don't see anything alarming, but then I don't know what a significant increase in velocity should look like!!

Are the velocity figures I've quoted in my posts on this thread a reason for concern?
