What do you hope to gain by going past the published max? If you’re only talking about 50 or 100 FPS then is it worth the decrease in the margin of safety?
In some lower pressure rounds (250 savage for example) I have gone past the max in a strong bolt action. In rounds such as the 308 however, I try to remember that the area between the published max and dangerous pressures is a very narrow path. Decide for yourself, but make sure you need or want to take the risk.
