Checking already loaded rounds, looking for empties or double charges

First topic message reminder :

A relative asked me if he could weigh his boxes of loaded 38 Special cartridges to confirm that they have powder in them.  My first thought was no way, but the more I thought about it, I'm not so sure that was the right answer.

He reloaded his used 38 Special cases, after tumbling them.  He used the same bulletin all of them - he was making wadcutter rounds for his Model 52.  He doesn't remember his powder load, but I'm 99% sure it was 2.7 or 2.8 grains of Bullseye.  Reloading was done on a Dillon 550B.

I suggested he take one box of questionable 50 rounds, weigh each one, and record the weight.  His bullet weight ought to be consistent, and while I don't know how much variation there might be in the case weight, I doubt it would be as much as 2.8 grains.

I suspect that after doing this, he could discard any rounds that seemed overly heavy or light, and shoot the ones that were close to the expected weight.  


He is 99.9% sure he never made any mistakes, but the idea of blowing up his gun if there was a mistake got to him.  
Your thoughts?

While a lot of good common sense suggestions were made above, I too strongly suggest not firing any suspect reloads.  Even a "barrel-less" revolver still has a chamber, and an overload could generate excessive pressures.  Be safe.

Not trusting someone else's reloads, I just finished hammering the bullets out of a free bag of 100 .41 magnum ammo I had from an unknown reloader.    Note said the primers are Fed MLP, with 10gr Unique.  I weighed 9 dumped charges to be 89.2gr out of the expected 90gr.  Pretty close.  But they were still unknown redoads.  I'll give the lead to Roddy and reload the new Winchester brass later, maybe.  My S&W 57 and 58 are near new condition.  I really have no need to shoot them.

Sorry to bring up my .41 unloading again.  But this might apply to any hammer bullet pulling....
I detected a fair amount of green powder mixed in with the Unique powder as I dumped it out.  upon looking at the primers still in the empty cases, it appears the primers did not survive the hammering.  So I deprimed the cases in a universal decapper.  Lots of green powder came out.  At least now I can clean the cases in soap and water.

Maybe the powder wasn't all the same? Ive never had a primer disintegrate on disassembley.
