As I am driven to do, I picked up a piece of Winchester .308 a couple weeks ago at the range, it went into the found brass case bag for cleaning and processing with all the others I had collected. As is my custom; I deprimed all the rifle cases with a lee depriming die and then cleaned it in the Ultra Sonic cleaner. As I started sorting out brass by caliber; one seemed odd, so I inspected it closer.
It has a Small Primer Pocket! See the case on the right and compare to the normal case on the left. Sure enough it's a Small Rifle primer pocket.

Head Stamp is Lapua Palma. I guess that some may have run across this; but for me it is absolutely UNIQUE. I am used to MilSurp US and NATO 7.62/.308 cases and the traditional Win/Rem/PMC/Nosler/etc.. cases. In almost 50 years of reloading first small primer .308W I have seen. Guess it's another outlier along with the Berdan Primed .308W cases that I'll have to be watching for.
(By the way, been saving those .308W Berdan Primed cases for Swaging 50BMG bullets some day when my supply of pulled 50BMG has been exhausted).
