Stopped by Gander to browse their current liquidation in preparation to reopen in November. Not much caught my eye. I did however walk out with a bag of once fired cleaned and prepped NATO brass... out of 250 pcs, 200+ are Lake City. I took pictures of the rest, in hopes someone recognizes them... If I remember correctly from browsing posts in the past, when reloading LC brass the case wall is thicker with less volume for powder. With powder charges about 1grn less than "factory" cases. Is this true, and if so I'm guessing I'll either want to run LC brass or "factory" brass and not mix the two for the particular rifle & load workup?
