Hello MDS Brain Trust,
I have a curiosity about the .277 Sig Fury round. I am not a re-loader or a bullet expert. According to some articles I've read, the Fury's casing is composed of a stainless steel base, an aluminum locking washer, and a brass case. The supposedly unique casing enables it to achieve extremely high pressures, and that is supposed to give the round a lot of energy.
My question is about a risk of galvonic corrosion from having different metals in contact during storage. I think in some conditions when aluminum is paired with brass it can result in galvonic corrosion. It's also possible with stainless steel and aluminum. Anyone have any thoughts about whether or not there might be a risk of this kind of corrosion in this particular casing?
This is just a curiosity about a new product that is going to in the field next year and possibly for decades after. I'm thinking about scenarios like storage conditions near marine or humid environments, especially for long periods. Or if a bunch of it is distributed and used by US military units in wet or humid conditions. I am wondering if the DOD buys a billion rounds of this stuff and stores a bunch of it for whatever use, will some of it be ineffective or dangerous if it's stored improperly?
Also, this round has a lot of energy, and would having a weakness at the aluminum washer & brass, or steel base & aluminum washer junction create safety issues? I'm wondering if improperly stored ammunition would result in some guns blowing up and personnel getting hurt. Is this ammunition going to require some white glove, no humidity storage for it to be reliably used in the field?
Any ideas on this one? Has anyone read anything about the .277 Fury testing or long term reliability testing data?
Maybe it would require specialized storage that would add to the cost of the program?
