Is there a hardened rule to when you need to start backing down powder charges as you seat bullets deeper or is it trial and error as you seat bullets deeper to look for increase in pressure. I understand that pressure does increase as bullets are seated closer to the lands but as bullets are seated deeper it doesn't raise pressures, as some tend to think, until you reach a point further from the lands that pressure starts to increase just as seating closer does. In fact you may be able to increase powder charge as you seat deeper or vise versa until you find that happy median. I understand that it's a process but was wondering if anyone has found, from experience, a rule of thumb that saves them time esp if you load a certain number of casings and find as you test deeper seatings that pressures start to increase and now you have to tear down casings and reload with lesser powder charges. I'm thinking there is no hardened rule because of the variables when it comes to bullet configuration, hardness of bullets, seating depths, throat dimensions. Thought I would ask. Thanks.
