[QUOTE="J E Custom, post: 1904136, member: 2736"] Sorry It is not clear, but I was simply trying to say reading pressure signs accurately takes experience and no one should depend on it to judge pressure. also when you begin to see signs, you are there or over the SAMMI recommended pressures. Reading pressure signs only tells you that you have excessive pressure, it only tells you that you have grossly exceeded the pressure when something fails. The loading manuals are only a guide and are rarely accurate so most will tell you start low and work up because they can't predict what your firearm will do with the load. What I was trying to say was, if you see some of the signs mentioned, don't try to guess what the pressure is, just back off until the signs disappear. As far as I know, No one can look at a case with these pressure signs and tell you how much pressure you have. even with experience all they can really tell you is it is to much. So my recommendation is to use the signs as a means of telling you that you are over max and need to back off. Just like a stop sign doesn't tell you to slow down. It tells you to STOP. Just because you get away with the rifle not blowing up for years with slight signs of pressure doesn't mean you are not over the design pressure, only that you have gotten away with it and shortened the life of all of your components and the firearm. Be happy with what you have and don't expect more than it can produce by exceeding the design pressure. (Even if you are not getting pressure signs, some brass will hide the the "Signs"by having a quality alloy or a better case design. Pressure is like thin ice, Travel at your own risk. Just my opinion having been there and done that. J E CUSTOM [/QUOTE]
