[QUOTE="nmbarta, post: 1594146, member: 78438"] You flew right past your max load. You did right by starting low, although I would have started a little lower than you did. (I also shoot a 7x300win with a 1:9 brux, which is better suited for the 180 class bullets) Everything you said from loose primer pockets after 3 shots, to ejector smudges, to blown primers are all signs of being WAY over pressure. Reading pressure takes time and learning what to look for can be tough without someone to actually show you. I guarantee, there were pressure signs way before this happened. Cratered primers, flattened primers, and ejector marks (not smudges) all happen before blown primers. Be careful man, you're pushing things to hard. I'm running 175's at 3150. I'm about 50fps below my max load. Your running 195's inside 100 fps of me and my barrel is 2" longer. Good luck with it, I think you'll have better luck with 175-180's with that twist. [/QUOTE]
