Morning Swede, what I'm saying is that rather than rely on pressure signs to know when you should stop increasing the charge weight, rely on your chronograph. So, when you hit the top end of velocities from your reloading manual, you're at the top end of safe charges for your rifle. Sometimes, with some loading manuals, you can exceed those but they're good guidelines.
Use the barrel length given with the reloading data; many loads are shot with 26" barrels and you shouldn't expect to duplicate those velocities with a 22-incher, or 24 for that matter. The general rule of thumb is 25 fps loss per inch of barrel length.
