Recently had the same issue with 300 win mag loaded with some h4350 Lots of corrosion split necks and clumped up powder some of the blue green corrosion was visible around the primers company has been notified of problem awaiting word from them 0 -
Poorly annealed case necks will always crack with extreme temperature variations. It has nothing to do with powder type or boxes it is stored in. 0 -

yep, but several different calibers, several different brass lots doing the same thing.

That is what I've seen with the H4831. I do know the H4831 will attract moisture (hygroscopic) and just a guess but suspect something similar to ammonia maybe.
]Did you contact Hodgdon's by phone, email, or ???
I've got several calibers re-loaded with H4350 and some of them are 15 years old or older of several different calibers and powder lots and not any sign of corrosion and the reloads stored and treated same as the H4831 that is corroding and I just recently used H4350 as a replacement for some H4831 in 06 reloads.
PM me or let me know what you find out from who you contacted?
Here is a link to more info about such. I placed info over at the other forum so as it would not get locked.

Should have qualified my reply a bit better reloads are at a gunsmith friend of mine that reloads with me . He is in process of contacting company . Sadly the cans we used were thrown away so we don?t have lot numbers . We loaded them about 5 years ago . He recently shot a few and discovers the neck splits and a blown primer that?s when we started pulling them down and finding the corrosion . I will keep you informed of what we learn About a year ago he bought an as yet unopened 8 pound keg of H 4350 0 -

You need to warn the guy to not try and shoot ANY OF THEM that some of mine were so weak that a bullet could have stayed in the barrel when they went poof and one bullet was stuck in the riflings when unloading the gun. If another had been run in and fired it could have bursted/exploded the receiver on the gun.0 -
We have already pulled down all the loads from that batch of powder all were bad some more so than others 0
