I am new at reloading ( 40 being the only caliber so far) I've processed maybe 750 rounds and shot them. At the onset (first 50 rounds) at the range i encountered a squib load, and being the newbie I am at reloading and the first time I had encountered a squib I was blind to the fact of what had happened. A round didn't fire and when I ejected it only the brass popped out.... it went over my head what happened. When I stupidly tried to load a live round behind it, it would not load (lucky for me) I then realized what had happened and said a few "thank you's" and rammed the bullet back out of the barrel. I was very attentive from that point on at the range that day. So "back at the ranch" I was thinking what can I do to help prevent that from happening again. I will be getting a powder cop soon for my press, and even a very small led light to allow me to see better what I am doing. But what I came up with for now is I weigh each loaded round.... I know brass, bullets, and primers don't all weigh the same as I found out before I loaded my first round, out of curiosity by weighing the bullets and brass separately. So what I have done now is I took randomly 10 bullets, 10 empty shells, and 10 primers to make up 10 samples of hardware ( no powder). I took my average weight as a median point and then used my highest and lowest weights as "no go" points. Having a digital scale i zeroed it out at the median weight unloaded round. So the end result is after loading a box of rounds I weigh each one and if the weight falls outside of my no-go values (too high or low powder weight)it gets set aside. For example after the the scale is zeroed to my median hardware weight, when I put a loaded round on it, it might read 3.4 or maybe 7.5 but they both are within my no-go values above or below my desired 5.4 powder charge weight. Of course some are probably still good, but the obvious ones that read 0.0, are obvious squibs. Anyone have any thoughts about this process?
