A potential theoretical way to reuse 5.7x28mm cases...

[M5-Shogun]

So I saw this youtube video:



I did some cursory research and discovered 5.7x28mm's base is within a few tenths of a mm of .308 or just a few hundreths off .311 (nominal Russian/Japanese bullet diameter). Nothing turning on a lathe theoretically couldn't fix.

I dunno if this is smart, but I wanted to pass on the idea to someone with more time on their hands and more experience. Using the technique here, could be an option. Dunno if you could swage the resulting brass to be a spitzer or anything, but I know just enough engineering to do napkin math here.

Anyways, food for thought. I'm not a reloader anymore, can't afford the space for it.

There have been a few similar threads lately. This is absolutely feasible and would be a good use for unusable brass. Also, a fully annealled case should size down in a push through sizer somewhat easily. I don’t have many sizers to experiment with yet, but I would absolutely give it a shot if I had what it took to make what I needed.

Good way to use 5.7 after 3-4 loading. That a out the life of the brass

Anyways, food for thought

Now you tell me, after I gave mine away.
