Okay, gents, I'm ready to start some serious testing on .380 loads. I have the powders selected, the range of loads in place, and the bullet chosen. All my reading on these forums cautions to "start low, and move up slow" regarding the charges, and to watch carefully for signs of overpressure. Hence, my question:
What, EXACTLY, are we to be watching for?
One guys says to watch for flattening on the primers, another says that flattening of the primers can be caused by things other than too much powder. I'm not in a hurry, I'm going to move carefully, but I'm not sure I understand just what I'm supposed to be watching for. Is it perceived recoil as well as flattened primers? Is it black marks on the outside of necks of fired cases?
Any clarification would be much appreciated!
thanks!
