308 brass sources?

I got 3k Lc once fired, from Brass bombers. Cleaned, deprimed and swaged, for $90/500. They were sold out of the "better" Long range stuff. Get that, if you can. The batch I got was supposedly fired in a machine gun, and stretched a little, which would reduce case life.
 
For the lc brass I would be looking for once fired (it never come new right?)

For other brands, I would be looking for new. I was trying to stay away from lapua, considering it's for a semi and they trash the brass pretty badly.

I'll check out brass bombers and cabelas. Thank you
 
So it seems like new Winchester brass might only be 10 cents a piece more expensive or so. (so only really like 2-4 cents a shot when reloaded multiple times).

Is the lc brass worth the savings? I have a small base die, so machine gun fired isn't a problem. However, I'm guessing it will never be as accurate as new Winchester brass?

This is for a semi, so that has to be kept in mind.
