This is a perfect example of why reloading needs the persons full attention. Got a call from a shooting buddy that I introduced to reloading a few months back during the summer. He was target shooting his reloads out in his back yard and went thru 54 rounds out of 200 that he reloaded the night before.
The 55th round was a squib, thank goodness he remembered the stuff I told him and he stopped firing and gave me a call and told me what happened. I told him I would be out in an hour, after I got there I dropped the mag, racked the slide back and using a brass rod I was able to tap the bullet back towards the chamber and then take it out. I looked at the spent brass that he fired and all had carbon traces in them except the squib case which had very little.
I told him you forgot to load the case and the primer alone pushed the bullet half way down the barrel. I also told him Kudos for stopping and calling me immediately. So we grabbed the other 145 loaded cases and headed to his man cave where he started to prepare the kinetic hammer to pull the bullets. I said first thing were going to do is take an empty primed case and shove a bullet into it and weigh it, note the weight of the dummy cartridge and subtract that figure from the weight of the loaded cases.
We hit jackpot on the 8th to last loaded shells that were left, I gave him a nice load of 4grs Bullseye with a 124gr speer jsp bullet that was a accurate load. Anyway that 8th to last cartridge weighed 8.9grs more than the dummy case which was more than a double charge. I told him to say a few prayers tonight before going to bed cuz if you would have fired that shell in your G17 Glock it would have probably been a KB and would have ruined his Tupperware.
He made no apologies for his mistake and admitted he wasn't paying full attention by not writing down where he left off before hopping in his car to go grocery shopping. Upon returning home he missed one case and double charged another. I told him I was going to post this on the nut as this is a good example of what happens when not paying attention.
