Typical pressure sign in a bolt rifle is heavy bolt lift so you obviously won't have that. Some of the old magazine articles occasionally suggested that you were OK as long as you had easy extraction. As Graybeard hints, when you have straight-side revolver cartridges sticking on extraction you are already way over the safe limit. As for primer reading, it's of limited usefulness and then only when you have a lot of experience with ONE particular primer in one particular gun, having read a lot of them starting with loads known to be light and working up. That is, a flattened primer may be a safe load and a normal looking primer may be a dangerous load. So, to answer your question, you don't get the same pressure signs in rifles and revolvers. Use the slower powders when you go for max published loads.
