So I've been on a reloading kick the last few weeks. Getting a lot done. Well last week I reloaded 2k rounds of 40 on the hornady LNL Ammo Plant. First 1k went fine I was watching the cases and churned them out really quick. Weighed charges frequently etc. With how smooth it went I figured I'd let the LNL loose and just go. Well the case feeder started giving me a bad time and while worrying about that I caught two cases without powder. So at the end I separated all rounds by headstamp and weighed them any variation over 2grs I pulled and noticed all were short on powder by as much as 4 grains. Normally I don't weigh the loaded rounds I just watch and weigh any charge that looks off while loading I have found any the was off by more the 0.1 grains.
What do you think do I need to pull them all and start over? Recipe as follows: Zero TCFMJ 165 gr 700x 5 grns 1.125" coal I like this recipe works well for me. |

Yep, weighing cases is useless. You don't have much choice but to pull them all and start over.
this is the tool you seek.. Ask me how I know.

IMO, weighing only works with the larger charges/calibers. For 9mm... man, sorry pull.
You other option is to take the risk. I wouldn't but it is an option. If you think you can stop if something feels wrong when you shoot, then fine. However, I had a friend miss some charges in his 30-06. Only thing that saved him was the fact that the bullet didn't go very far on just the primer causing the next round not to feed. That happened 2X during our shooting session. We told him to stop shooting that ammo (especially around us). If someone can't tell the recoil is off with a 30-06, then 9mm might be a mistake waiting to happen. If you are brave, try shooting a few without powder and see how it feels and how the gun shoots. My recommendations above are only for data collection purposes. Nothing I would try in the field. Good luck and sorry to hear. It's definitely a learning opportunity. Get the powder lockout die. |

I have to agree with the others. I have tried weighing loaded pistol ammo and it simply does not work. Especially if using mixed brands of brass but even then I soon realized that I was getting differences that were more than the powder charge weighed.
It's even hard with rifle ammo. Unless you are using pre weight matched brass. Even then you better be looking for something significant. Motor |

4 gr is huge.... Do you by chance have the large drum in your powder measure? Quoted:

...I pulled and noticed all were short on powder by as much as 4 grains... 4 gr is huge.... Do you by chance have the large drum in your powder measure? Actually when sorted by headstamp and weighed there wasn't more than 50 that fell more than one grain outside of the average weight of that headstamp. I pulled, anything weighing more than two grains outside of average. Some were as much as 3-4 grains off by weight. But, I found that the charge was off by pretty close to what they weighed at. (If that makes sense) The rotor was the correct one. It was that stupid case feeder that messed up that was making me not focus on where I was at in the stroke etc.... I, actually going to do some more testing with the weights and powder charges and hopefully post up what I find. |
