Norinco 45 ACP Ammo Concerns

Ok fine, you guys should all get a mortar & pestal to grind up your varget and see if the pressure is different. I haven't done this because logic dictates it would be stupid. It may change nothing, who knows, but it's really dumb. There's nothing wrong with shooting ammo that has a little surface corrosion on the rim.

Is there proof that tumbling causes powder to break up any more than handling, transporting, etc.? I think of crates of military ammo bounced around in trucks on dirt roads - isn't that worse than tumbling for 15 minutes to clean up the corrosion?
 
It's a common practice when bulk reloading rifle ammo to tumble the assembled cartridges for a short while to get the case lube off. I have yet to hear of anyone getting killed doing this.

Note I said a short while. I don't know at what point it becomes dangerous, but a short while is not going to make your #### fall off.

Precisely! There was a thread here a while back that detailed an experiment of tumbling live rounds for days and then the powder was examined...no change. A quick google search will also reveal people who have tumbled rounds with various types (flake, ball, etc.) of powders for months! They pulled a few rounds every week or so and ran them over the chrony...again no change.

I'm not a "shiny brass is necessary" kind of guy, I shoot my Norinco 45s and 223s corrosion and all and cannot be bothered to tumble them. But it is not for any other reason than the fact that I know they shoot the same regardless of how pretty they look and they will all get shined up later when I reload them.

Exactly. Myths and old wives tales live on forever until common sense prevails.

If you think it may blow up in the tumbler: Do Not Stand There Watching It! Go To Another Room!

If this was an issue, do you not think there would be warnings all over the tumbler manual and shipping box.

I've never seen, Warning: Do Not Use This Product With Live Ammunition!

After all we live in a world of litagations and people suing at a drop of a hat.

Here is an interesting look at powders before and after tumbling with some cool pics:

I have shot 1000's or rds. of this stuff and have had only a few failures. For the price it cannot be beaten. I am about to order some more once my huge order of 223 comes in. Thanks

yeah dont worry about it fired thousands of it and its all like that... comes off when I tumble it, if you are really concerened put it through a tumber for a few hours, but wont hurt anything
 
its not corrosion, the metal is not being eaten away, its just dirt basically (dust+primersealer+mould who knows, its just random dirt)
dont worry about it, tumble it off, or shoot it as normal...

sned me the brass if you dont want it lol :)
