[QUOTE="cajun, post: 2000760, member: 9772"] Recently on another forum a guy was reloading following book data and broke a bolt in an AR and had a case seperation. The guy had a chrono but no alarm bells were going off in his head when he was getting 150 fps over max load with a 4” shorter barrel. I know we, myself included, loaded for years without one but I consider it a safety issue. With a tight chamber you can be below max loads in a manual and be over pressure. It’s also common to find different load data using the same components from different sources. The first step for me in new load development is running a 1 shot ladder over the chrono to find max velocity and pressure in my rifle. [/QUOTE]
