Thanks Mr. Whiz. I forgot to mention that detail in my original post. When I shined a light down the case I noticed 2 dimples and wondered if they were berdan primed. Seems a shame. I picked up about 60 cases. Normally, other than rimfire, the brass at the range is dominated by .223 and 7.62 X 39 (and much of it is cheap, steel cases) Don't usually find much I can use, and then it's generally not more than 4-10 cases. Curse that cheap, Soviet ammo!
