Just a heads up based on my experience. I bought two 150rd boxes of WINCHESTER Forged 9mm ammo, 115gr, STEEL case. I've been buying Winchester products for about 60 years. This ammo and some .22 I recently bought must be some of the most worthless junk I've ever seen. The steel cases look like they were retrieved from a land fill. They are chalky and look almost corroded. Had one stick in my barrel and had to tear down the gun and use a dowel to remove. I suspect if you wipe down each round with some lube right before you shoot it will function, but I would never leave it in my 43x for any self defense purpose. Sorry Winchester, you lost a 60 yr customer.
