If you want to measure pressure, the only system currently in production for handloaders that I am aware of is the RSI Pressure Trace. You can use it in conjunction with QuickLOAD and a chronograph to tweak the QL powder model to match your particular lot of powder better. I use one for three things. One is duplicating load performance. Another is to alert me to the echo of muzzle pressure spikes from using too slow a powder for the bullet weight (see a couple of examples lower down on that page I linked to). A third is that I generally try to stay under 58,000 psi unless I absolutely have to go higher, based on Geoffry Kolbe's observation that barrel erosion tends to grow exponentially with pressure above around that number.
