[QUOTE="Plinker147, post: 2282198, member: 88320"] I had a rifle that I could only get good accuracy when it had slight pressure signs, about identical to what OP is showing. I hunted with that load for a few years without issue. A flat primer, and slight ejector marks are signs of pressure. It doesn't tell you how far from safe you are. In that same rifle I could load another full grain of powder and the pressure signs didn't change(visibly) I have middle the road load's that show ejector marks on cases all the time. It doesn't mean they are unsafe just shows signs of being fired with X amount of pressure. Reading pressure is a total of all signs, flattening primers, sticky bolt (probably best indicator) and deep ejector marks, excessive brass stretching, short brass life than you would expect. You need to pay attention to all signs. The problem with operating with the pressure signs is its always in the back of your mind wondering is it hotter today than when i normally shoot, did i make a slight mistake reloading and I'm half gr hotter? Its best not to put yourself in those situations and rework you load to find the accuracy without pressure signs. 50fps means nothing on a bigger scale. That's my 2 pennies on the subject [/QUOTE]
