IN my experience, case life is the most reliable indicator or pressure. If you can reload a case 5 or more times without the primer pocker getting lose, or other indicators, you're not over the limit for pressure.

I typically load 5 cases, and run them over a chronograph. When I start getting close to max/factory velocity, I look closely for pressure signs, and then start loading the same cases over and over. If I get to 5 loadings with a particular load, and the primer pockets are still tight, I know that load is safe.

Often, I get pockets starting to loosen up after 2 or 3 reloadfs, long before book max. Sometimes, not often, I get well over book max and still get the 5 reloads.
