I don't have any of my load manuals right at hand but that load seems on the light side to me. A lot light really. Unique is a dirty burning powder to begin wiht and a light load is even worse due to the incomplete combustion of the powder. I have always found that Unique is best on the warm side of all loads. My advice would be a tight crimp and start working up on the load staying within safe limits. If the 500 to 600 FPS velocity range is what you are looking for then a powder switch would be wise. A 125 grain bullet at 500 to 600 FPS range could be acheived nicely with Bullseye. That powder is not perfectly clean but is lots better than Unique.
