I'm wanting to learn a little more about working up to max loads. Lets say you make a bunch of loads with charge increasing in .2 increments and take them to the range to test for signs of over pressure. You of course realize that not all rounds need to be fired and signs of excess pressure might mean that any remaining rounds with a larger charge get pulled instead of fired.
All that said, are there any signs of pressure that are considered safe or do you back off immediately upon seeing the smallest indicator? I'm not a user of +P+ rounds but to use those for an example they would be over pressure but considered safe. Would they actually show signs of being over pressure? Is a round that shows pressure say on the brass far above the pressure a +P+ factory round produces?
