terrebonne, or
is it possible to over tumble your brass? the reason i ask is i started my tumbler yesterday with approx 50 rounds for my 338 in it. watching tv etc.. and fell asleep, woke up and turned it off after it had tumbled for approx 9 hours lol. they were really clean but is that harmful?

lol cool deal, they sure are shiny as hell now after 9 hours of tumbling

Re: is this possible?

same here...I know my WSSM brass is built rough and tough anyway, and I usually do at least 100 for 10-12 hours over night.
 
Re: is this possible?

Yeah, haven't used any of the nickel brass since tumbling it off. Gonna just toss out those cases. Found them at the range though. Just left them too long in the tumbler. The other brass seems just fine though.
 
Re: is this possible?

I believe the original reason for nickel-plating cartridge cases was to prevent corrosion on rounds carried in leather cartridge loops on handgu holsters, etc.

On a rifle round, "awesome" probably is the principle purpose.
 
Re: is this possible?

Dick Whiting has tested tumbling LOADED 223 ROUNDS for from 10 minutes to 7 days. By testing, I mean firing over a chrono for group and velocity.

He has seen no difference in performance of the loads across that full spectrum of time.

My guess is your brass is good.

[quote do not reload nickel. [/quote]

I have loaded lots of nickel cases with no issues at all. It takes just a split sec more heat when you anneal cases but i have not found one issue with them.
They make nice looking loads and the cases don't tarnish like brass cases do when you start handling them. IMHO nothing wrong with them at all.
 
Re: is this possible?

It is not that nickel is a continual problem, it is that it can be a huge problem.
Nickel is very hard and subject to flaking off when reloaded. I have had this happen more than once. Normally not a problem. IF it comes off and is not noticed, it can really scar a chamber or die. For me, I do not need the brass badley enough to put up with the risk. Generally, you will have no problem with it. Most nickel brass is not as high quality as the best non nickel brass so for me it is an easy decision to not run the risk on it.
 
Re: is this possible?

I inherited some factory primed nickel Win .280. Loads and reloads fine for me. It's probably good for LE carry ammo and hunting, where there's more to stand up to. I don't load so much of it, so there's probably no real issue with the dies, etc.; and I clean and oil my dies spotless after each useage anyway
