Vinegar means it has suds left.......
My nose has never failed me.
It's an odd smell but once you smell it you always remember.
The only thing I'd do is start at the low end and work up some loads with a chronograph and see what it's doing velocity wise, while keeping an eye on the cases and pockets.
I believe powder will start appearing again. Keep in mine that most powder is imported, all Hogdon is, from Australia.
I just bought 1000 308's in Federal OFMB, 500 OF and 500 primed but not loaded, in Federal Lake City. I'm finding Sierra GK'a and MK's in 308 and 338 and I just bought 500 22 cal FMJBT Hornady's from Natchezz of all places. They had a 1000 bullet limit but I only needed 500 to replensih my inventory. Last week I got 5 100 boxes of Hornady V-Max in 22 caliber from Midway and I don't see prices increasing that much.
The V-Max's were the same price I paid a year ago and the 22 caliber FMJ's climbed 2 bucks a hundred while the brass was actually a bit cheaper than last year when I bought some so I don't see the gouging that everyone is crabbing about.
Maybe some AR's and AK's, hell I made a small fortune selling 4 AK's I had (worthless guns IMO) but some folks wanted them real bad, so I obliged. I made enough outright on 4 AK's to order a full custom for myself..... That is actually accurate, unlike an AK.
