[QUOTE="snox801, post: 2484829, member: 54383"] So what if I had no brass flow, primers looked good then had just very noticeable bolt drag backed off and that’s where I ended? How is that any different that what I would do with a PRC. Second I’ve been loading long enough to know just cause one rifle doesn’t get get to the FPS of another didn’t mean either is over pressure. Velocity is not the proven way to measure pressure. Lots of factors go into that. Seems to me if the vast majority of 30 Sherman owners are independently coming up With the same velocity using the known and safe ways of looking for pressure, that tells me that not everyone is way over pressure. Maybe it’s that fact that the case is just in the sweet spot of efficiency. Here is an example, you say no way 1 gr can make that big of difference. Well look at the 25-06 vs .257 Roy. One could say that every 25-06 is 100 percent over pressure because look how much less powder it uses to achieve the same speed as the Roy. I’m juts saying I use the same method for every single load I do. I go to the very first sign of pressure not matter where it comes form then back off. How is it just this one and only one that is not safe? Seems to many very experienced loads on here that I trust end up around the same speed for me to believe that it’s way over pressure. [/QUOTE]
