[QUOTE="MagnumManiac, post: 904270, member: 10755"] I'm sorry, but those pics and the accompanying text mean absolutely nothing, no mention is made of the actual pressure that made those primers look like that, what brand they were, all that is obvious is that a general assumption has been made. I have the Pressure TraceII system and I have seen primers such as the one on the end in that pic appear well below max pressure, as I stated, primer appearance means nothing unless you can compare it to a known standard, the same reason we now know that CUP testing was hit and miss and not accurate at all. First time loaders SHOULD take primer appearance as a guide to stop increasing the load when flat primers appear within the listed book loads, but it is NOT in any way telling you what pressures your loads are running at. They could be at max pressure, but they could also be well below max pressure. [/QUOTE]
