I keep reading postings where reloaders write about not seeing pressure signs like flattened primers, sticking cases, etc. All of this is when writing about loads that should be at 44,000 CUP MAX. Well, I don't see pressure signs with my rifle that fires the .338 WIN MAG at 54,000 CUP. And you won't see the pressure signs with the Weatherbys that run at 55,100 CUP. If you want to see the pressure signs, then you will have to go beyond the pressures that the magnums run at. I have had pressure signs while working up magnum loads. It usually came from making a change in components or methods, like crimping or not crimping. That is why you should start back at the low point and work up. If you want to be a load developer then get one of the pressure testers that connect to the barrel of your gun. But if you want to depend on pressure signs then you shouldn't be shooting the mid pressure range rounds.
