Just got my first chronograph, graduating into a little more in depth reloading I guess, or a least gradually able to afford a few more tools! My question is, while working up loads, are there indicators in velocity progression that indicate dangerous pressures? I mean if your working up say .5 gr increments in your charges, what do you watch in your velocities and extreme spread to dictate what the pressure is doing? I know a few of the simple indicators, primers flowing around the firing pin, split necks, difficult bolt opening, ejector pin marks on the case head, (are their any others?). But from what I read on here it sounds loike ya'll can observe pressure with what the velocity does on your load work ups?? Just curious!
